Creates a legal form called an "irrigation trust" that can be established by two or more primary producers to provide, manage and operate shared irrigation and/or drainage infrastructure (application, incorporation by Gazette and vesting of nominated property) (ss 4–5).
Gives an irrigation trust corporate status with powers to build, maintain and operate channels, pipes, pumps and other infrastructure, to acquire or lease land, to inspect and enter land for planning and maintenance, and to borrow and secure money on trust property and revenue (ss 24, 25, 54).
Sets out member governance: who is a member, how the presiding member is appointed and removed, meeting procedures, voting (votes normally valued by water allocations or licences) and rule‑making powers (ss 6, 8–12).
Allows trusts to fix "irrigation rights" for members when the trust holds water licences, and to permit surrender, transfer or permanent transformation of those irrigation rights into individual water licences subject to external water law (ss 29–34).
Authorises trusts to set water supply and drainage charges, declare minimums and interest on late payment, and recover unpaid charges as a charge on land or as a debt (ss 41–52). A trust may sell land where charges remain unpaid for one year (s 52).
Enables trusts to limit, suspend or reduce water supply in specified circumstances (shortage, poor quality, reduced allocation under other water laws, non‑payment or breach of conditions) and exempts trusts from civil liability for actions under that power in some circumstances (s 35; see s 59 for liability protections).
The Irrigation Act 2009 establishes a statutory framework for creation, governance, operation, financing and enforcement of irrigation trusts in South Australia. Mechanically, it:
Provides the route to create a trust by application to the Minister by at least two persons engaged in primary production (s 4(1)-(3)), and requires establishment by Gazette notice (s 5(1)-(2)). A trust established under the Act is a body corporate with perpetual succession and a common seal (s 5(3)).
Sets out internal governance: membership rules, meeting procedure, voting values tied to water allocations or other criteria (ss 6, 8-12), boards of management and the ability to delegate functions (ss 17-18).
Confers functions and operational powers to provide, maintain and operate irrigation and drainage systems (ss 23, 24), including inspection and entry powers (s 24(k), (l)) and appointment of authorised officers (ss 37-38).
Creates a regime for fixing irrigation rights and for transforming those rights into individual water licences, subject to the Landscape South Australia Act 2019 and Commonwealth water rules (ss 29-34).
Authorises trusts to raise revenue by declaring water supply and drainage charges (ss 41-44), fixes procedural safeguards for declaring charges (publication in a local newspaper, 21 days' notice for resolutions: ss 42(1), 47), and provides enforcement mechanisms for non‑payment including creating a charge on land and sale of land after one year of arrears (ss 50-53).
Provides audit and financial reporting obligations (ss 19-21), borrowing powers and security over revenue (s 54), and limits member liability (s 9).
Establishes appeal routes to the Environment, Resources and Development Court against specified trust decisions (s 55) and prescribes offences, penalties and evidentiary presumptions for enforcement (ss 39, 61-63, 67).

Sourced from South Australian Legislation (legislation.sa.gov.au), CC BY 4.0.
Provides enforcement and compliance tools: appointment of authorised officers with inspection powers, offences for unauthorised use or interference with trust systems and penalties, and procedures for notices and requiring specified works by landowners connected to a system (ss 37–40, 62–63, 40(4)–(7)).
Requires financial reporting and audit of trusts, and makes audited statements and reports available to members and the Minister (ss 19–21).
Permits Ministerial involvement at key points: approval to establish/amalgamate/dissolve trusts, specifying vesting or disposition of property and water licences on dissolution, and the power to regulate (ss 4–5, 13, 14–15, 70).
Provides for appeals to the Environment, Resources and Development Court on a defined range of decisions (membership discontinuance, fixing irrigation rights, directions to do work, dissolutions and other prescribed matters) and for suspension of trust decisions pending appeal (ss 55–57).
Who it affects
Primary producers who form or join an irrigation trust, and landowners/occupiers on land connected to a trust's irrigation or drainage system (ss 3, 8, 41–52).
Members and boards of management of trusts (ss 17–18).
Non‑member persons who may be supplied or drained by a trust under agreement (ss 26–27).
Ministers and officials who approve establishments, amalgamations or dissolutions and who interact under related water statutes (ss 4–5, 13, 14–15).
Creditors, auditors, and buyers of land subject to charges (ss 20, 52, 54).
Why it matters (official claim and practical tests)
The long title and text present the Act as a framework to manage shared irrigation/drainage infrastructure and associated water entitlements. That claimed purpose is implemented by: creating a trust vehicle (ss 4–5), setting governance rules (ss 6, 8–12), enabling rights and charges (ss 29–52), and providing enforcement (ss 37–40, 62–63).
Testing that claimed purpose against costs, incentives and trade‑offs (concrete mechanisms cited):
Who pays: Members, owners and occupiers pay charges and interest fixed by the trust (ss 41–48, 50). If unpaid for a year, the trust may sell land to recover sums (s 52). Owners may also bear costs directed by the trust to build, modify or maintain on their land if the trust serves notice (s 40(4)–(7)).
Who decides: Trust members and their boards set most operational rules, irrigation rights and charges by resolution (ss 6, 11, 29, 41–47). The Minister decides on establishment, amalgamation and, subject to consultation and statutory process, may dissolve a trust and determine vesting of water licences and property on winding up (ss 4–5, 13, 14–15).
Compliance burden and reporting: Trusts must keep proper accounts, prepare audited financial statements and lay them before annual general meetings; auditors have statutory access to records (ss 19–21). Trusts and members must follow rule‑making, notice and voting procedures (ss 6, 11, 47).
Bureaucratic discretion and legal constraints: The Minister has statutory discretions (approval of establishment/amalgamation, dissolution vesting decisions) and regulations can confer further discretionary determinations (s 70; ss 4–5, 13, 14–15). Several trust powers and outcomes are made subject to other water laws (explicit cross‑references to the Landscape South Australia Act 2019, the River Murray Act 2003 and Commonwealth water rules in ss 23(6), 32–33 and elsewhere), which constrains some trust actions and transformation processes (ss 23(6), 32(4)–(5), 33(3)).
Effects on private choice and markets: Trusts can supply non‑members under agreement, and irrigation rights may be transferred, surrendered or transformed to individual water licences (ss 26–27, 30–33). Trusts set charges and rules for connection and use (ss 6, 40, 41–44), which affects the price and availability of delivered water and the ability of independent providers or users to connect or trade. The Act requires trusts not to unreasonably restrict activities that support water trades (s 34).
Concentrated benefits and diffuse costs: Members who govern a trust control rule‑making and charge settings (ss 6, 11–12, 41–47), which concentrates decision rights. Costs (charges, compliance, possible works ordered by the trust) are borne by owners and occupiers across the serviced area (ss 40, 41–52).
Implementation risk and interaction with other laws: Key trust actions (holdings of licences, transformation of rights, reductions in supply tied to other Acts) are expressly subject to other water laws and Commonwealth rules, creating legal and operational dependencies that a trust must manage (ss 23(6), 32(4–5), 33(3), 34).
Practical points for participants
If you are a landowner or occupier connected to a trust system, you may be liable for charges and directed works, and failure to pay can lead to sale of the land after statutory steps (ss 40, 50–52).
If you are a member, voting weight is normally tied to water allocations or licences but can be changed by a qualified resolution, which affects governance outcomes (s 12).
Trusts must operate financial controls (audits), and may borrow against revenue — creditors can apply to the Supreme Court for revenue appropriation directions if debenture obligations are not met (ss 19–21, 54).
Source of purpose claims and limits
The Act itself describes its purpose (long title and ss 23–24). Those purpose claims are implemented through the specific powers, duties, financial rules and Ministerial roles described above. The Act also repeatedly makes trust actions subject to other statutes and Commonwealth rules (notably the Landscape South Australia Act 2019 and the Water Act 2007), which legally limits or conditions several trust powers (see ss 23(6), 32(4–5), 33(3), 34).
The Act explicitly cross‑references and constrains trust behaviour by other water laws. It requires trusts, when setting terms for supply, to comply with the Landscape South Australia Act 2019 and not to impose requirements that would make a person act in breach of the River Murray Act 2003 or Commonwealth water rules (s 23(6)(d)-(f)). Transformation of irrigation rights and trades are expressly made subject to those Acts and rules (ss 32(4)-(5), 33(3)-(4)). The Act therefore sets a self‑contained corporate and charging framework for local shared irrigation/drainage infrastructure, while anchoring water‑entitlement outcomes to state and Commonwealth water law.
The Minister retains significant decision rights throughout establishment, amalgamation and dissolution (ss 4-5, 13, 14-15), including the power to determine vesting of property or water licences on dissolution (s 14(7); s 15(6)). The Act also contains transitional provisions preserving trusts and allocations under the repealed Irrigation Act 1994 (Sch 1 Part 4).
This section states what the Act does mechanically. The Act’s stated policy rationale is not repeated here as a justification; instead subsequent sections analyse the operational concepts, who pays, who decides, incentives created by the charging and entitlements rules, compliance burdens, and the channels through which costs and benefits flow, with citations to the relevant provisions.
Main concepts
The Act revolves around a small set of interlocking legal concepts that determine operational control, entitlement, revenue raising and enforcement.
Irrigation trust as a corporate vehicle. A trust established by the Minister under ss 4-5 is a body corporate (s 5(3)). It can hold property, sue and be sued, acquire land (s 24(e)), borrow (s 54), and grant licences or leases over land it owns (s 24(5)). Trust rules may regulate membership, operations and fees (s 6(1)-(2)), and bind members and the trust (s 6(5)). The Act excludes trusts from certain Corporations Act s 5F matters (s 69).
Membership and governance. Membership is initially those who authorised the establishment application (s 8(1)); others can be admitted by resolution or according to rules (s 8(2)). Governance is by members, a presiding member and optional deputy (s 8(4)-(7)). A trust may appoint a board of management drawn from members for day‑to‑day operations (s 17). Voting values are generally proportional to water allocations or licences (s 12(6)) but may be altered by a high‑threshold resolution (s 12(7)-(10)).
Irrigation rights and water licences. Where a trust holds water licences for supply to members, it must fix irrigation rights for each participating member (s 29). Irrigation rights can be expressed as volume or units (s 29(5)). Members may surrender or transfer water available under irrigation rights and irrigation rights themselves may be surrendered or transferred among members, subject to trust processes (ss 30-31). The Act allows permanent transformation of irrigation rights into individual water licences, but only where the transformation can take effect under the Landscape South Australia Act 2019 and in compliance with Commonwealth water rules (s 32).
Charges, recovery and security. Trusts may declare water supply and drainage charges to recover costs and provide for maintenance and capital (s 41). Charges must be declared by notice in a local newspaper for the relevant year (s 42(1)) and the trust must resolve charges with 21 days' notice (s 47). Charges and associated interest can be secured as a charge on the land under a scheme to be provided by regulation (s 51(1)) and unpaid charges may be recovered as debts or by sale of land after one year of arrears (s 51(3), s 52(1)-(4)).
Delegation, inspection and enforcement powers. Boards and trusts may delegate powers in writing (ss 18, 36). Trusts may enter and inspect land in planning and operations (s 24(j)-(k)), appoint authorised officers with powers of entry, inspection and sample taking (ss 37-38), and direct landowners to carry out works to protect or facilitate systems (s 40(4)-(7)). The Act creates offences for obstruction, false information and unauthorised interference or use (ss 39, 61, 62-63) with quantified maximum penalties and expiation fees.
Interaction with other water law. The Act repeatedly makes its operation subject to the Landscape South Australia Act 2019 and Commonwealth water rules, and prohibits trusts from imposing requirements that would cause breaches under the River Murray Act 2003 (s 23(6)). Transformations and trading are expressly conditioned on the operation of those instruments (ss 32-34).
These concepts determine who decides (members, boards, the Minister), how rights are specified and moved (irrigation rights, conversion to licences), how revenue is raised and enforced (charges, security on land, sale), and the interface with higher‑order water legislation that limits the trusts’ practical autonomy (s 23(6); ss 32-33).
Who it affects
The Act creates legal duties and rights that directly and indirectly affect a defined set of actors:
Members of irrigation trusts. Persons who carry on primary production and who either authorised the original application or are admitted under rules are members (s 4(1), s 8(1)-(2)). Members vote at meetings (s 12(1)), may hold irrigation rights (s 29), and can be liable for charges and interest in relation to serviced property (s 50(1)). Membership itself does not confer title to trust property (s 9(1)) and, except for pre‑incorporation debts, members are not personally liable for trust debts (s 9(2)-(3)).
Landowners and occupiers of serviced property. The definition of serviced property (s 3) captures land used for primary production that is connected to a trust’s irrigation or drainage system. Owners and occupiers of serviced land are both the primary payers of water supply and drainage charges (ss 41-44; s 50(1)) and jointly and severally liable for unpaid amounts (s 50(1)). They are also subject to notices to construct or maintain infrastructure, to erect fences, and to other directives from the trust for efficient supply or drainage (s 40(4)-(6)). Landowners who divide land are affected by section 60, which preserves existing rights but allows the trust to refuse new connections and not to extend systems.
Non‑members who contract with trusts. The Act expressly allows trusts to supply water or drainage services to persons who are not members under contract (ss 26-27, s 49(1)-(2)). Those contracts can fix payment terms outside the charges regime; amounts under agreements are not subject to the Division’s charging provisions (s 49(2)).
Creditors and financiers. Trusts may borrow and secure revenue streams and property (s 54). Creditors can apply to the Supreme Court for directions to appropriate revenue or require the trust to raise charges to satisfy debenture obligations upon default (s 54(3)). The trust’s ability to charge land for unpaid bills (s 51) creates an asset for creditors.
The Minister and other public agencies. The Minister has establishment, amalgamation and dissolution powers (ss 4-5, 13, 14-15), may impose terms on dissolution notices (s 14(9)), and must be consulted before vesting water licences on dissolution where the Landscape South Australia Act responsibilities apply (s 14(8), s 15(7)). The Minister must approve charges or interest rates if the trust is indebted to the Crown above a specified threshold (s 48(1)).
Courts and auditors. The Act creates appeal rights to the Environment, Resources and Development Court for specified decisions (s 55) and prescribes constitution and composition requirements when that Court exercises jurisdiction under the Act (s 58). Trusts must prepare audited financial statements annually and may not appoint a member as auditor; auditors have statutory access to records and persons (s 20).
Authorised officers and trust personnel. Trusts may appoint authorised officers and issue identity cards; authorised officers have entry and inspection powers (ss 37-38). Persons acting on behalf of trusts (including board members) are afforded protection from civil liability for honest acts or omissions in performing statutory functions (s 59(1)-(2)).
The economic incidence of costs and benefits is concentrated. Immediate payers are owners and occupiers of serviced properties who must pay declared charges and may be subject to required works (ss 41-44, 40(4)). The trust (and therefore its members collectively) receives the benefits of maintained infrastructure and any surplus revenue for capital works (s 41). The Minister exercises decision rights that can change the identity of the entity holding water licences or property on dissolution (s 14(7); s 15(6)), transferring both control and associated liabilities.
Key duties and rights
The Act imposes a set of specific duties on trusts, members, landowners and authorised officers, and creates corresponding rights.
Duties of trusts:
Establishment and rule obligations. The trust must maintain rules that comply with any prescribed requirements and not be inconsistent with the Act; rules can set fees, use times and other operational matters (s 6(1)-(2), (5)). The trust must furnish its up‑to‑date rules to the Minister on request (s 6(7), penalty $500).
Operational functions. Trusts must provide, maintain, operate and manage irrigation and drainage systems (s 23(1)), and must operate in a financially responsible manner, including raising adequate capital for maintenance and improvements (s 23(7)-(8)).
Compliance with other water law. When determining terms for supply or holding water licences, trusts must ensure compliance with this Act, the Landscape South Australia Act 2019 and any requirements under the River Murray Act 2003, and the Water Act 2007 (Cth) (s 23(6)(c)-(f)).
Financial reporting, audit and accountability. Trusts must keep proper accounts (s 19), prepare financial statements according to recognised accounting standards and have them audited by an eligible auditor (s 20(1)-(4)), and lay audited statements and operational reports before the annual general meeting (s 21(1)).
Charging and notice obligations. Trusts must set charges by resolution with 21 days' notice (s 47) and publish declarations of water supply or drainage charges in a local newspaper (s 42(1)).
Rights of trusts:
Powers to construct, acquire land, enter and inspect, fix irrigation rights, supply water under agreement to non‑members, and to impose charges (ss 24, 26-27, 29-31, 41-44).
Delegations to boards, officers or other bodies, subject to non‑delegable powers (ss 18, 36). A trust may not delegate powers under s 12 (voting rules) or s 33 (devolution of water licences) (s 36(2)).
Enforcement and recovery: power to restrict supply or reduce irrigation right allocation in specified circumstances (s 35), power to treat unpaid charges as a charge on land under regulations and to sell land after one year of arrears (ss 51-52).
Duties and rights of members and landowners:
Members must participate in governance, pay charges where applicable, and comply with rules and conditions of supply (ss 6, 8, 40(3)). Members may transfer or surrender irrigation rights and water available under rights subject to trust procedures (ss 30-31).
Owners and occupiers are jointly and severally liable for charges and interest for serviced land and must be served notice of amounts payable (s 50(1)-(2)). They must comply with notices under s 40, failing which the trust can take action and recover costs (s 40(7)).
Powers and duties of authorised officers and auditors:
Authorised officers may enter land at reasonable times, inspect material, take samples and photos, and ask questions related to operations (s 38). They must produce evidence of appointment before exercising powers (s 37(4)).
Auditors have access rights to records and may require information from officers and employees; refusal to assist an auditor is an offence (s 20(4)-(5), penalty $5 000).
Ministerial powers and duties:
Decision on applications to establish trusts and to approve amalgamations (ss 4(3), 13(4)), establishment and dissolution by Gazette notice (ss 5(1), 14(5)-(6), 15(4)-(6)).
On dissolution, the Minister determines the vesting of water licences and property and may specify terms and conditions on members and owners (s 14(7)-(9)). The Minister must consult the Minister responsible for the Landscape South Australia Act 2019 before dealing with water licences (s 14(8), s 15(7)).
Appeal rights and judicial review:
A person may appeal to the Environment, Resources and Development Court against particular trust decisions, including membership discontinuation, fixing of irrigation rights and directions under Part 5 (s 55). Time limits and relief powers of the Court are specified (s 55(2)-(3), s 56).
These duties and rights create a closed system where operational control resides primarily with the trust and its members, revenue‑raising is via statutory charges or negotiated contracts, and the Minister retains supervisory and exit powers. Compliance obligations are concentrated around financial reporting, meeting procedures and adherence to broader water law constraints. Enforcement powers are administrative (restriction of supply) and coercive (charge on land, sale), with statutory protection for trust actors performing duties in good faith (s 59).
Penalties and enforcement
The Act combines civil enforcement mechanisms, criminal offences, administrative remedies and statutory presumptions to secure compliance. The enforcement architecture and penalties are as follows.
Criminal/penal offences and penalties:
Hindering authorised persons and abusive conduct: s 39 makes it an offence to hinder or use abusive language against persons acting on behalf of a trust or authorised officers, or to refuse to answer questions, or to falsely represent oneself as an authorised officer. Maximum penalty $5 000 (s 39).
False or misleading information: s 61 penalises furnishing information to a trust that is false or misleading in a material particular, maximum penalty $5 000.
Interference with infrastructure: s 62 criminalises unauthorised interference with any part of an irrigation or drainage system or trust property used in irrigation/drainage. Maximum penalties differ by offender type: $100 000 for a body corporate, $20 000 for a natural person; expiation fee $750.
Unauthorised use of water: s 63 penalises taking water or using water from a trust’s system without authorisation or for unauthorised purposes, same penalty band and expiation fee as s 62.
Auditor obstruction and similar hindrances: s 20(5) penalises refusal to allow auditors access or giving required information, maximum penalty $5 000.
Expiation regime: for certain offences (s 40, s 62, s 63) an expiation fee is prescribed,e.g. $750,per the relevant provision.
Administrative enforcement powers:
Restriction, suspension or reduction of supply: s 35 permits trusts to restrict or suspend water supply or reduce irrigation right allocations where supply cannot meet demand, water quality is unsuitable, conveyance water shortfall, non‑payment of charges or other specified breaches. Importantly, a trust incurs no civil liability for action taken under s 35 (s 35(4)).
Directed works on land: s 40(4) allows a trust, by served notice, to direct a landowner to construct or modify works, install equipment, erect fences, or otherwise remedy issues for efficient supply/drainage. If the owner fails to comply, the trust may enter the land, do the works and recover costs as a debt (s 40(7)). Failure to comply with the notice itself is a criminal offence with the penalties noted under s 40(8).
Recovery of charges and security: unpaid charges and accrued interest can be made a charge on land under a scheme established by regulation (s 51(1)). Charges not paid can also be recovered as a debt (s 51(3)). Where charges secured on land are unpaid for one year, the trust may sell the land (s 52(1)), subject to statutory notice requirements to owner, occupier and mortgagee and advertising rules (s 52(2)-(6)). The statute prescribes the order of application of sale proceeds (s 52(9)).
Civil liability protections and presumptions:
Protection from civil liability: s 59(1) protects a person from civil liability for an honest act or omission in exercising powers or duties under the Act; s 59(2) shifts such liability to the relevant irrigation trust. Subsections (3)-(4) specify contexts where trusts are not liable for certain losses, e.g. rises/falls in water levels, escape of water except where the trust knew or should have known and failed to act, and actions taken to comply with Landscape South Australia Act or River Murray Act duties (s 59(3)-(4)).
Evidentiary presumptions: s 67 establishes statutory presumptions in prosecutions and recovery proceedings, e.g. that an allegation about ownership, authorisation to take water, or authorised officer status is taken as proved in the absence of contrary proof. Trust allegations as to amounts payable or ownership/occupation of land are similarly presumed proved absent contrary evidence (s 67(1)-(2)). Production of a purported newspaper is prima facie proof of publication (s 67(3)).
Procedural protections:
Appeals: affected persons have appeal rights to the Environment, Resources and Development Court in relation to specific trust decisions (s 55), decisions can be stayed pending appeal by the trust or the Court (s 56), and trusts or members can appeal a Minister’s dissolution proposal (s 57). The Court has powers to affirm, vary or substitute a decision, remit for reconsideration or make ancillary orders (s 55(3)); powers on dissolution appeals are similarly broad (s 57(3)).
Operational features relevant to enforcement:
Notice and record keeping obligations. Many enforcement mechanisms trigger only after specified notice periods or processes: e.g. notice requirements to propose resolutions (21 days for a resolution, s 3(4); s 47), notice of charges in a local newspaper (s 42(1)), and pre‑sale notice requirements (s 52(2)-(3)).
Regulated details. The scheme for charges as a charge on land, the rate cap for interest on late payments and the minimum period before interest is payable are all to be prescribed or controlled by regulation (s 46(2)-(3); s 51(1) cross‑references to regulations).
The enforcement package mixes administrative tools (restrict supply, direct works), property security (charge on land, sale), and criminal or civil penalties for obstruction, false information and unauthorised interference. The Act also provides protections to trust actors for honest performance of duties and provides evidentiary presumptions in favour of trusts and the prosecution. Those presumptions and protections affect litigation posture and evidentiary burdens in enforcement actions.
How it interacts with other laws
The Act is explicitly drafted to operate alongside, and subordinate in certain respects to, higher‑order water and land laws. The statutory text identifies several specific interfaces and constraints:
Landscape South Australia Act 2019. The Act makes multiple provisions contingent on compliance with, and subject to, the Landscape Act. Trusts must ensure that terms and conditions for supply, holding or dealing with any water licence comply with the Landscape South Australia Act 2019 (s 23(6)(d)). Transformations of irrigation rights into individual water licences are effective only if they can take effect under the Landscape Act and members seeking licences comply with its requirements (s 32(1)(c), s 32(4)). The Minister must consult the Minister responsible for the Landscape Act before vesting or dealing with water licences on dissolution of a trust (s 14(8), s 15(7)). The Act’s 2019 amendments (Legislative history: 2019 Sch 5, cll 33-44; commencement 1.7.2020) updated several provisions to align with the Landscape Act as noted in the legislative history.
Water Act 2007 (Commonwealth). The Act repeatedly requires trusts to act consistently with 'Commonwealth water rules' and the Water Act 2007 where relevant. For example, any security required in transformation of irrigation rights must be consistent with Commonwealth water rules (s 32(2)), and trusts must ensure compliance with requirements imposed by or under the Commonwealth Water Act in holding or dealing with any water licence (s 23(6)(f)). The Act also forbids trusts from unreasonably restricting activities that support water trades under Commonwealth and other laws (s 34).
River Murray Act 2003. Trusts must not impose requirements that would result in a person breaching duties under the River Murray Act 2003 (s 23(6)(e)). Subsection 59(4) excludes trust liability for actions taken to meet duties or requirements under the Landscape Act or the River Murray Act, or to further their objects or the Objectives for a Healthy River Murray.
Land Acquisition Act 1969. Trusts may acquire land pursuant to contract with the owner or through the Land Acquisition Act, but acquisition by means of the Land Acquisition Act requires the written approval of the Minister (s 24(3)-(4)). This creates an interlock with state compulsory acquisition procedures.
Property law and conveyancing. The vesting of land in trusts on incorporation or amalgamation and the registration of interests require action by the Registrar‑General, and in various cases instruments evidencing vesting are exempt from stamp duty (s 5(4)-(5), s 13(8)-(9)). The trust’s ability to create charges on land for unpaid charges (s 51) and to sell land for non‑payment (s 52) operates within the registration and conveyancing system, including special provisions where land is held from the Crown.
Corporations Act 2001 (Cth). The Act declares certain matters to be excluded matters for the purposes of s 5F of the Corporations Act in relation to Corporations legislation to which Part 1.1A applies (s 69), placing trusts outside particular Corporations Act constructs addressed by that section.
Unclaimed Money Act 2021. The Act’s Schedule references and legislative history note that sums payable to owners after sale where the owner cannot be found are to be handled under the Unclaimed Money Act 2021 (s 52(10) as amended; legislative history entries).
Operational implications of these interfaces:
Limit on autonomy: trusts’ power to allocate, transform and trade water entitlements is explicitly limited by the Landscape Act and Commonwealth water rules (ss 32-34). This reduces unilateral authority to create individual licences or effect transfers without satisfying external statutory requirements.
Administrative coordination: Ministerial consultation obligations and the need for trust compliance with upstream licensing regimes (s 14(8), s 15(7), s 23(6)(d)-(f)) create a requirement for administrative coordination between trusts and state and Commonwealth water agencies.
Regulatory detail deferred: key operational mechanisms,how charges become a charge on land, prescribed interest caps and minimum interest periods, and certain fines,are to be settled by regulation (ss 46(2)-(3), 51(1), 70(2)(d)). That means practitioner advice must consider subsidiary regulations for the full rule set.
In short, the Act creates a layer of local corporate and charging law for irrigation/drainage systems but keeps substantive water rights and transformations tethered to state and Commonwealth water law. Practitioners must therefore read the Act in tandem with the Landscape South Australia Act 2019 and applicable Commonwealth rules for transactions involving water licences or transformation of irrigation rights.

2019 (No 25) Statutes Amendment and Repeal (Simplify) Act 2019: Assent 3.10.2019. Part 25 (ss 51-53) commenced 3.10.2019 (s 2(1)). The history shows amendments to s 14(7) and s 15(6) by s 51 and s 52 of that Act respectively.
2019 (No 33) Landscape South Australia Act 2019: Assent 21.11.2019; Schedule 5 (clauses 33 to 44) commenced 1.7.2020 (Gazette 25.6.2020 p3502). The legislative history notes multiple consequential amendments: e.g. s 3(1) (definition amendments), s 23(6) amended by Sch 5 cl 36, s 29(5) amended by Sch 5 cl 37, s 32 and s 33 amendments at Sch 5 cll 39-40, s 35 amendments by Sch 5 cl 41, s 40(4) amended by Sch 5 cl 42, and s 59(4) and s 14(8)-(15) impacted.
2021 (No 45) Unclaimed Money Act 2021: Assent 25.11.2021; Schedule 1 (clause 7) commenced 25.11.2023 as noted. This affected s 52(10).
The legislative history also lists specific provisions varied, where entries show which sections were amended or deleted and by which instrument,for example deletions under the Legislation Revision and Publication Act 2002 are recorded (s 2 omitted; Pt 1-3 of Schedule 1 omitted), and other amendments such as deletion of s 16 by the 2019 Act. The history identifies the commencement dates for each change.
For practitioners advising on present‑day operation, the key amendments to note from the history are the 2019 Landscape South Australia Act changes (which explicitly tether irrigation right transformations and trust obligations to the Landscape Act) and the more technical changes affecting vesting, registration and electronic conveyancing (2016 amendments) and handling of unclaimed sale proceeds (Unclaimed Money Act 2021). The legislative history in the source is the authoritative record of these amendments and their commencement dates; any advice must cross‑check the operative text and schedules for current versions of each section.
Litigation history
The Act itself contains procedural and remedial provisions that create litigation pathways, but the statutory text appended here does not record any judicial decisions or reported litigation. The only litigation‑related content in the Act is the statutory appellate framework and court constitution provisions:
Appeals to Environment, Resources and Development Court. A person may appeal against specified trust decisions (membership discontinuance, fixing of irrigation rights, directions under Part 5, and other classes prescribed by regulation) to the Environment, Resources and Development Court (s 55). Appeals must be instituted within one month of written notice of the decision or within further time the Court considers reasonable (s 55(2)). The Court may affirm, vary, substitute a decision, or remit the matter for reconsideration (s 55(3)).
Stay of decision pending appeal. The trust or the Court may suspend the operation of the decision pending determination of the appeal (s 56).
Appeal against proposal to dissolve trust. An irrigation trust or a member may appeal a Minister’s proposal to dissolve the trust under s 15 (s 57). Time limits and relief powers are set out in s 57.
Constitution of the Court. The Act specifies how the Environment, Resources and Development Court is to be constituted for these matters; in particular commissioners with expertise in irrigated farming or management of water resources may be designated to sit (s 58).
Because the statutory text as provided does not include any reported cases or litigation summaries, there is no litigation history arising from the Act contained in the source. Practitioners seeking precedent must therefore consult court databases and reports for decisions under the Act. The statutory presumptions in s 67, the evidentiary rules and the protections in s 59 may be significant in litigation, and the Act’s appeal provisions prescribe time bars and relief that shape procedural strategy (ss 55-57). Any recorded litigation outcomes will necessarily be found in external case law repositories rather than in the Act text supplied.
Gotchas
The Act contains several provisions that can produce unintended outcomes or operational risks unless identified and managed. These are practical "watch points" for advisers and administrators, anchored to the statute.
Ministerial discretion on establishment, vesting and dissolution. The Minister decides whether to establish or amalgamate trusts (s 4(3); s 13(4)) and may determine vesting of property and water licences on dissolution (s 14(7); s 15(6)). A trust’s members do not have unilateral control over post‑dissolution outcomes where the Minister chooses alternative vesting or to attach terms and conditions to dissolution notices (s 14(9)). The Minister must consult the responsible Minister under the Landscape Act before vesting water licences (s 14(8), s 15(7)), but the statutory discretion is broad.
Trust charges remain valid even if Ministerial approval omitted. If a trust is indebted to the Crown above $50 000 it must obtain the Minister’s approval before declaring charges or fixing an interest rate (s 48(1)). However, subsection (2) states that non‑compliance does not affect the validity of a declared charge or interest. Practically, this means a trust’s failure to secure required Ministerial approval does not void the charge; it creates political and administrative risk but limited legal invalidity for the charge itself.
Charges may be declared retrospectively. Section 42(4) allows trusts to declare a water supply charge after the period to which it relates has commenced. That can create disputes about billing, expectations and cashflow for irrigators if declarations are made late in a financial year.
Voting values and high‑threshold changes. Default voting values are proportional to water allocations or licences (s 12(6)). A trust can alter the basis of values under s 12(7), but such a resolution requires 80% of votes cast and 21 days’ notice (s 12(9)‑(10)). The high threshold makes substantial governance changes difficult and may entrench vote distributions tied to historical allocations.
Transformations of irrigation rights are tightly constrained. Transformations require compliance with the Landscape South Australia Act and Commonwealth water rules (s 32(1)(c), s 32(2), s 32(5)). If a water licence held by the trust is subject to a recorded interest, member consent may be required before devolution (s 33(2)). Section 33(5) also preserves the Minister’s discretion to refuse the grant of a licence on specified grounds in the Landscape Act. Practically, a member’s expectation that an irrigation right can be converted into a licence may be frustrated by external licensing rules or registered interests.
Trusts can restrict supply for non‑payment without civil liability. Section 35(1)(g)(i) permits restriction or suspension of supply where the owner/occupier has failed to pay charges; s 35(4) states a trust incurs no civil liability for action taken under the section. This creates strong administrative enforcement leverage and limited redress for affected irrigators except via appeal mechanisms or possibly damages where the trust acted in bad faith (subject to s 59 protections).
Sale of land process and priority of proceeds. The trust’s power to sell land for unpaid charges after one year (s 52(1)) carries procedural steps (service of notice, service on mortgagees, public auction requirements, advertising in state‑wide newspapers) and prescribes the order in which sale proceeds are applied (s 52(2)-(9)). A purchaser takes title free of mortgages and charges except in some Crown tenure cases (s 52(12)). That outcome can extinguish encumbrances and should be watched by mortgagees and purchasers.
Evidentiary presumptions favour trusts. Section 67 creates statutory presumptions (e.g. ownership, amounts owing, publication of notices) are proved in the absence of contrary proof. Practically, this shifts certain evidentiary burdens onto defendants and debtors, making challenge more demanding.
Delegation limits. Trusts cannot delegate powers under s 12 (voting rules) or s 33 (devolution of licences) (s 36(2)). That means member votes and decisions regarding the policy course to devolve water licences must be exercised by the trust itself, not outsourced, which matters for governance where management is otherwise delegated.
Regulatory detail deferred. The Act delegates critical technical matters to regulations: the scheme to charge land (s 51(1)), caps on interest (s 46(2)) and fines under regulations (s 70(2)(d)). Until those regulations are consulted, important operational details remain uncertain.
Liability shift and limited trust liability. Section 59 protects persons acting honestly, and shifts liability to the trust for honest acts; s 59(3)-(4) enumerate situations where the trust is not liable. While this shields individuals, it also concentrates legal exposure on the trust entity and, ultimately, its members’ collective interests.
Transition complexity. Pre‑existing trusts continued under Schedule 1 Part 4 (s 5) retain prior allocations and rules until varied; transitional provisions (Sch 1) may create legacy governance or allocation states that differ from newly created trusts.
These items are concrete statutory features that often cause friction in practice. Operational planning and legal advice should explicitly address each point, confirm subsidiary regulations, and map licence transformation pathways through the Landscape South Australia Act and Commonwealth rules.
How to comply
Compliance with the Act requires attention by trusts, boards, members, landowners and advisers to statutory procedures, reporting, notice and substantive constraints created by other water laws. Below is a practical compliance checklist anchored to statutory provisions, suitable for trust administrators and advisers.
Formation and registration:
Application to Minister: ensure an application to establish a trust is made in the prescribed form by a person authorised by at least two primary producers (s 4(1)-(2)), accompanied by the prescribed fee and any regulatory information requirements (s 4(2)).
Distinctive name and Gazette notice: receive Ministerial approval and ensure the trust is established by Gazette notice specifying commencement date and name, and secure corporate attributes (s 5(1)-(3)).
Property vesting and registration: if the application identifies property to vest in the trust, verify prescribed consents and ensure the Minister’s notice specifies the property so vesting occurs on incorporation; apply to the Registrar‑General to register land vesting (s 5(4)-(5)).
Governance and procedural compliance:
Adopt and maintain rules that comply with prescribed requirements and do not conflict with the Act (s 6(1)-(2)). Keep rules accessible but understand that third parties are not presumed to have notice (s 6(6)). Produce rules to the Minister on request within the specified period (s 6(7)).
Convene annual general meetings and other meetings in accordance with notice requirements: at least once a year (s 10(2)), with at least 7 days written notice for meetings generally (s 11(3)), and 21 days’ notice where the Act specifies a 21‑day rule (s 3(4), s 11(5), s 47).
Keep minutes of proceedings (s 11(7)). Ensure quorum rules are followed (s 11(2)-(3)) and voting procedures reflect the statutory or trust‑determined values (s 12).
Financial and audit obligations:
Maintain proper accounts in accordance with recognised accounting standards (s 19, s 20(1)). Prepare audited financial statements as soon as practicable after each financial year and have statements audited by an eligible auditor who is not a member (s 20(1)-(3)).
Ensure auditors are afforded full access to records and employees, and do not obstruct auditors; obstruction is an offence with a penalty (s 20(4)-(5)).
Lay audited financial statements, auditors’ reports and operational report before the AGM (s 21(1)), and provide copies to the Minister or any member upon request (s 21(2)).
Charging, billing and recovery:
Fix the factors for water supply and drainage charges and the amounts by resolution with 21 days’ notice (s 47). Publish charge declarations in a local newspaper (s 42(1)). If imposing a minimum amount credit it appropriately (s 43).
Ensure interest rates on late payments do not exceed regulatory caps and that minimum periods before interest are applied match regulations (s 46(2)-(3)). Specify whether interest is simple or compound (s 46(4)).
Where the trust is indebted to the Crown above $50 000, seek Ministerial approval before declaring charges or fixing interest rates (s 48(1)). Note non‑compliance does not invalidate charges but creates a breach of the Act (s 48(2)).
Use the regulatory scheme for creating charges on land (s 51(1)). Serve notices specifying amounts payable to owners/occupiers as required (s 50(2)), and follow the statutorily required steps and timeframes before selling land for non‑payment (s 52(2)-(6)). Comply with advertising and notice requirements to avoid procedural challenges.
Operations and system protection:
Appoint authorised officers in writing and issue identity cards, and ensure authorised officers produce evidence of appointment before exercising powers (ss 37(1)-(5), 38). Train authorised officers in the limits of their powers and in evidence collection (s 38(b)-(d)).
Issue and serve notices under s 40 when directing landowners to undertake works; set clear dimensions and specifications as required by s 40(6), allow compliance time, and if entering land to carry out works recover costs as a debt (s 40(7)).
If restricting or reducing water supply under s 35, ensure the trust documents the factual basis (e.g. water supply shortfall, quality issues, reduced allocations under the Landscape Act) and that proportional reductions comply with the requirement to mirror reductions under the Landscape Act where applicable (s 35(3)).
Irrigation rights, transformations and trading:
When a trust holds water licences for member supply, it must fix irrigation rights by resolution on a fair and equitable basis having regard to crop types and other relevant matters (s 29(2)-(4)). Record these resolutions and the basis used for fairness and potential appeal scrutiny.
For surrender, transfer or transformation of irrigation rights, follow the trust’s specified procedures for notices, application fees, security and timeframes (ss 30-32). Ensure any security required is consistent with Commonwealth water rules (s 32(2)) and reasonable so as not to unreasonably restrict trading (s 32(3)).
For complete devolution to member water licences, follow s 33’s procedural and consent requirements, especially where licences are subject to recorded interests (s 33(2)-(4)). Coordinate with the agency administering the Landscape Act for licence issuance and variation (s 33(3)).
Recordkeeping and evidentiary readiness:
Keep accurate records of ownership, occupation, readings and meter data. The Act permits meter‑reading assumptions where readings occur within 14 days of charging period changes (s 3(3)). Maintain clear audit trails to rebut statutory presumptions under s 67 when necessary.
Ensure publication evidence for local newspaper notices is retained to meet evidentiary standards for declarations and notices (s 67(3)).
Legal and regulatory coordination:
Coordinate closely with the state agency administering the Landscape South Australia Act and with Commonwealth agencies as required for compliance with Commonwealth water rules (s 23(6)(d)-(f); s 32(2), s 32(5)).
Before acquiring land by compulsory means refer to the Minister and follow Land Acquisition Act requirements (s 24(3)-(4)).
Dispute management and appeals:
Preserve appeal rights information in notices (s 55(2)). Consider suspension of decisions pending appeal where appropriate (s 56).
Use the Environment, Resources and Development Court’s constitution rules when selecting evidence and experts; note the requirement that commissioners with expertise in irrigated farming or water management may be designated (s 58).
Practical checklist items:
Maintain up‑to‑date rules and make them available to members.
Adhere strictly to notice and quorum rules for resolutions, especially where 21 days’ notice or 80% thresholds apply (s 3(4); s 11(2); s 12(10)).
Keep robust financial systems to meet audit timelines and to document charges and billing histories for recovery and sale proceedings.
Document all interactions with Ministers or other agencies when approvals or consultations are statutorily required (s 48, s 14(8), s 15(7)).
Following these steps will address the principal statutory obligations in the Act. Practitioners must supplement this statutory checklist with subsidiary regulations and with procedures mandated by the Landscape South Australia Act and applicable Commonwealth water rules for actions affecting water licences and allocations.
