The plan uses a small set of recurring legal concepts which determine rights, administrative discretion and compliance requirements.

• Plan area and map: The plan applies only to the geographic area shown on the schedule 1 map and whose boundary is held digitally by the department (s 4, s 5). The schedule and the department’s digital representation are thus the determinative spatial sources of applicability; the plan does not define boundaries in the operative text.

• Water to which plan applies: The plan expressly covers water in watercourses, lakes or springs, and overland flow water (s 6). Groundwater and subterranean water are not referenced as water to which the plan applies; however, later sections (pt 6, s 27) require reconsideration of the plan if taking or interfering with underground water might affect outcomes.

• Outcomes and balancing: The plan establishes outcome objectives comprising “general outcomes” (continued use of water entitlements, economic activity, efficient use) and “ecological outcomes” (minimising changes to natural flow regimes, maintaining riparian health and freshwater outflows to The Narrows) (ss 7-9). The statutory language requires seeking a balance between those general and ecological outcomes (s 7).

• Chief executive decision-making and constraints: The plan constrains the chief executive’s ability to make decisions that would increase the total volume that may be taken in the plan area (s 11). The constraint is subject to enumerated exceptions that preserve certain existing or statutorily required decisions (s 11(3)).

• Overland flow regulation: Overland flow water is regulated tightly. Taking overland flow water is generally prohibited except where specifically authorised: stock or domestic use; taking via low-capacity works of up to 5 ML; authorisations under the resource operations plan; contaminated agricultural runoff; diversion around mine sites; planning and environmental approvals; or an authority under s 15 for existing works (s 13). The definition of permissible “works” includes the 5 ML capacity ceiling and excludes works physically connected to other storage works (s 13).

• Existing works regime: Owners of land with existing works (other than those allowed by s 13(a)-(g)) may continue to take overland flow water for one year after commencement and longer if they notify the chief executive in the approved form and supply further required information (s 15). The chief executive may translate such authority into a water licence under the Act s 212 and impose conditions to ensure the average annual volume does not exceed pre-commencement levels (s 16).

• Unallocated water cap and allocation process: The plan caps allocation of unallocated water at 5,500 ML annually across all purposes, and at 500 ML annually for town supply unless the chief executive allows more where no viable alternative exists (s 19). Dealing with unallocated water must be through the process set out in the resource operations plan (s 20), and the chief executive must consider specified matters including demand, alternative sources, ecological impacts, and cultural values when dealing with unallocated water (s 21).

• Measurement and monitoring: The resource operations plan must state monitoring requirements that assist the Minister to assess strategy effectiveness, and the chief executive may impose monitoring/reporting requirements under the plan (s 23). Water licences under the resource operations plan may include measurement conditions (s 17(4)(d)) and the chief executive may require engineer certificates about works (s 17(3)).

• Implementation and amendment mechanics: The instrument contemplates an implementation schedule requiring a resource operations plan to be prepared within three years (s 25). Minor amendments are specified and may be made under the Act (s 26), while the Minister must consider replacing or amending the plan where authorisations are insufficient or underground water risk threatens outcomes (s 27).

The plan therefore blends outcome-setting, hard ceilings (volume caps, overland flow prohibitions), transitional grandfathering (s 15), administrative discretion with constraints (s 11, s 17), and delegated operational detail to the resource operations plan and departmental processes (s 16, s 20, s 23). Each of these concepts informs who can take water, how much can be taken, what evidence the chief executive may require, and how changes will be implemented.

Several categories of actors are affected directly and indirectly by the plan. Identify who pays, who decides, and who must change behaviour.

• Private landowners with existing works: Owners of land who already have works that take overland flow water are directly affected. Section 15 allows such owners to continue taking for one year after commencement, and beyond that provided they give notice in the approved form and any further information reasonably required by the chief executive (s 15). Those owners may face obligations to provide information and may be subject to replacement licences under ss 16-17 if the chief executive is satisfied there has been an increase in average annual take.

• Prospective licence applicants and existing licence holders: Anyone seeking a new water licence, or holding an existing licence, is affected by the plan’s annual volumetric limit rules (s 12), and by the ceiling on increasing total take in the plan area (s 11). For licences that state irrigated area rather than volume, the chief executive converts to a volume up to an area times 7 ML per hectare ceiling (s 12(1)(b)).

• Users of overland flow water and downstream users: Section 14 requires the chief executive, when deciding overland flow applications, to consider likely adverse effects on natural aquatic ecosystems and downstream users (s 14). Thus downstream irrigators, wetland-dependent stakeholders and community values are implicated in application decisions.

• Municipalities and town water suppliers: The plan limits allocations for town water supply to 500 ML annually, unless the chief executive otherwise allows more where no viable supply exists (s 19(2)-(3)). Local government water planners and supply authorities therefore face a statutory cap and a requirement to demonstrate insufficiency and lack of alternatives to exceed it.

• Agricultural and grazing operations: Farm operators who rely on ponded pasture, water spreading and other overland flow uses find particular restrictions. Ponded pasture and water spreading are explicitly excluded from permitted overland flow taking under s 13(b) and defined in s 13,those activities are not authorised under the general exception for works. Agricultural users that might rely on overland flow for fodder production will therefore need to rely on other statutory exceptions or obtain a licence under the resource operations plan process.

• Mining and petroleum operators: The plan provides targeted exceptions that recognise mining needs. Overland flow water may be diverted around a mine site up to the amount necessary to satisfy that requirement (s 13(1)(f)). However, other taking related to mining or petroleum activities is excluded from some environmental approval exceptions, for example s 13(1)(e) refers to development permits for environmentally relevant activities other than mining or petroleum activities.

• Environmental authorities and developers: Environmental authorities issued under the Environmental Protection Act 1994 and development permits for certain ecologically relevant activities are explicit exceptions allowing taking of overland flow water to the amount necessary to satisfy those authorities (s 13(1)(e)). Project proponents with such approvals must ensure their water use remains within the necessary amount and may still be subject to the chief executive’s consideration under s 14.

• Indigenous and cultural stakeholders: The plan requires the chief executive to consider cultural values, including local Aboriginal cultural values, when dealing with unallocated water (s 21). This embeds consideration of cultural interests into allocation decisions, although the plan does not prescribe a particular decision outcome.

• The chief executive and the department: The chief executive is the principal decision-maker under the instrument, subject to the plan’s constraints and the Act. Responsibilities include refusing decisions that increase total take (subject to exceptions), assessing and granting licences under ss 16-17, preparing and implementing the resource operations plan within the implementation schedule (s 25), specifying monitoring requirements (s 23), and considering specified matters in unallocated water dealings (s 21).

• The Minister: The Minister receives monitoring information to assess strategy effectiveness (s 23) and must consider amending or replacing the plan when specific triggers relating to insufficiency of authorisations or underground water risks arise (s 27).

Who pays and bears compliance costs? The plan shifts administrative compliance costs to licence holders and prospective applicants through information and certification requirements (s 17(3)), notification obligations to continue existing works (s 15(3)), monitoring and measurement obligations as provided in the resource operations plan (s 17(4)(d), s 23), and the need to apply for allocation of unallocated water under the resource operations plan (s 20). Developers with environmental authorities may retain limited rights to take small amounts of overland flow water but must still show that the amount is “necessary” for their authority (s 13(1)(e)). The chief executive and department bear administrative costs of implementing the resource operations plan, monitoring, and making allocation decisions under constrained caps.

In sum, the plan directly affects landowners with existing works, licence applicants and holders, agricultural and town water users, extractive industries, cultural stakeholders and the administering department, by setting ceilings, authorising limited exceptions, and creating administrative evidence and monitoring requirements.

The plan creates specific duties, rights, and discretionary powers. Below are the main obligations for private actors and the decision-making powers and duties of the administration, with section references.

Duties and rights of private actors

• Notification to preserve existing use: Owners of land with existing works must give notice in the approved form and any further information reasonably required if they wish to continue using those works beyond one year after commencement (s 15(2)-(3)). Absent notice, the entitlement to continue is time-limited to one year.

• Compliance with overland flow prohibition: Persons may not take overland flow water other than in the circumstances listed in s 13(1). Those circumstances limit rights to stock or domestic use, specified low-capacity works, authorisations under the resource operations plan, environmental and development permits to the necessary amount, diversion around mine sites to the necessary amount, contaminated agricultural runoff, or under a s 15 authority (s 13(1)(a)-(h)). The plan therefore creates a default prohibition and a set of enumerated statutory exceptions.

• Measurement and monitoring compliance: Where a water licence under the resource operations plan contains a condition that water be measured as stated in the resource operations plan, licence holders must comply with that measurement method (s 17(4)(d)). The resource operations plan must state monitoring requirements for water and natural ecosystems to assist Ministerial assessment (s 23). Private actors who hold licences may be required to meet those monitoring and reporting duties, although the precise methods are left to the resource operations plan.

• Limits on irrigation-area-based licences: If a licence states irrigated area rather than volume, the chief executive determines the volume needed to irrigate efficiently but not more than the area times 7 ML per hectare ceiling (s 12(1)(b)). Licence holders with area-based licences therefore have a conversion right but bounded by the statutory ceiling.

• Use-based limitations: Licences that state volume get that stated volume as the annual volumetric limit; other licences are limited by volumes decided by the chief executive having regard to conditions, works capacity, historical take in the previous 10 years, and use efficiency (s 12(1)(a), (c)).

Duties and powers of the chief executive and Minister

• Prohibition on decisions increasing total take: The chief executive must not make a decision about allocation or management of water that would increase the total volume that may be taken in the plan area, with explicit exceptions (s 11(1)-(3)). This is a duty that constrains future allocations.

• Decision-making criteria for overland flow applications: In deciding applications under the Act about taking overland flow water, the chief executive must consider whether granting the application will likely adversely affect natural aquatic ecosystems and downstream users (s 14(1)). That requirement introduces specific environmental and downstream-user considerations into the merits assessment.

• Licence replacement and conditioning: Where the chief executive is satisfied that average annual overland flow take has increased from pre-plan operating arrangements, the chief executive may grant a water licence under s 212 of the Act to replace a s 15 authority and may impose conditions to ensure average annual volumes do not exceed pre-commencement levels (s 16). The chief executive may also require an engineer’s certificate from the authority or licence holder regarding works capacity and take rates when granting or amending such licences under the resource operations plan (s 17(3)).

• Considerations for dealing with unallocated water: When allocating unallocated water, the chief executive must consider specified matters including need, efficiency of existing uses, alternative water sources, alternative supplies, impacts on water quality, habitat connectivity, seasonality, estuarine ecosystems, sediment movement, inundation of habitats, species movement, recreation, cultural values, imposing flow conditions to protect low flows, and impacts on water users (s 21(1)(a)-(e)). The list is non-exhaustive for the chief executive.

• Monitoring and reporting obligations for the department: The resource operations plan must state monitoring requirements to help the Minister assess strategy effectiveness for the outcomes in pt 3 (s 23). The plan also contemplates that the Minister report on the plan under the Act (s 24 references Act s 53).

Rights created or protected

• Continuing use of existing works: There is an express right to continue to use existing works for a specified transitional period and beyond if the owner complies with notice and information requirements (s 15).

• Right to a licence conversion with constraints: Owners of existing works whose continued use is authorised under s 15 may obtain a water licence under s 212 of the Act replacing that authority, subject to chief executive satisfaction and possible conditions to limit average annual take (s 16).

• Access to unallocated water under process: Unallocated water may be made available for allocation under the resource operations plan process (s 20), but subject to the statutory annual caps (s 19) and the chief executive’s mandatory considerations (s 21).

Key administrative limitations and safeguards

• Exceptions to the no-increase rule: Section 11(3) lists exceptions to the chief executive’s duty not to increase total volume. These include decisions required under the resource operations plan and certain reinstatements or permits, meaning the plan’s no-increase rule is not absolute.

• Minister-level plan review triggers: The Minister must consider amending or replacing the plan if authorisations are not sufficient or if underground water risks affect outcomes (s 27). This creates a statutory trigger for plan review where specified risks materialise.

In summary, the instrument creates specific duties on private actors to notify, measure and restrict overland flow taking, and places mandatory considerations and limits on the chief executive’s discretion, while delegating operational detail and monitoring to the resource operations plan and departmental practices (ss 11, 13-17, 19-21, 23).

The plan text itself does not specify criminal penalties or enumerated enforcement sanctions for breaches. Instead, enforcement and sanctioning mechanisms are implicit through references to processes and instruments under the principal Act and the resource operations plan. The plan therefore relies upon the Act and subordinate instruments for enforcement detail.

What the plan provides directly about enforcement

• Administrative control via licences and authorisations: The plan converts existing authorisations into water licences under the Act (s 16) and contemplates that licences may include conditions such as maximum volumes, average annual volumes, maximum take rates and measurement requirements (s 17(4)). Compliance failures with licence conditions, measurement obligations or monitoring requirements will therefore be addressed through the regulatory and enforcement apparatus provided by the Act and by the terms of individual licences, not through express penal clauses in the plan.

• Monitoring and Ministerial oversight: The resource operations plan must state monitoring requirements to help the Minister assess the effectiveness of the strategies (s 23). Monitoring requirements are a compliance mechanism because they provide the factual basis for detecting non-compliance and for the chief executive or Minister to act. The plan also contemplates reporting to the Minister under the Act (s 24 reference), which is an administrative oversight route.

• Conditions on licence replacement: Where existing works continue by notice under s 15 but the chief executive finds that average annual take has increased, the chief executive may grant a licence under s 212 of the Act and impose conditions ensuring average annual take does not exceed pre-commencement levels (s 16). Those conditions create enforceable regulatory obligations once on the licence.

What the plan leaves to the Act and resource operations plan

• The instrument repeatedly refers to the Act, resource operations plan, and the chief executive’s powers under the Act (see s 16 which specifically references s 212 of the Act). The plan does not attempt to duplicate the Act’s enforcement mechanisms, for example powers to issue infringement notices, prosecute offences, or issue remedial directions. Those functions and associated penalties are governed by the Act and the resource operations plan, which is the operational instrument the plan requires to be made (see s 25).

• Measurement and monitoring enforcement: The plan permits licences to require measurement methods as set out in the resource operations plan (s 17(4)(d)). The resource operations plan will likely specify measurement standards, reporting intervals, and non-compliance consequences, but those details are not provided in this plan.

Practical enforcement pathways implied by the plan

• Licence condition enforcement: Once the chief executive places volume or rate limits, or measurement obligations, on a licence granted under the resource operations plan, the central enforcement pathway will be by administrative action under the Act and potential civil or criminal sanctions for breach of licence conditions contained in the principal Act.

• Revocation, amendment or replacement: The plan gives the administrative authority scope to replace s 15 authorities with licences (s 16) and to amend licences having regard to works capacity and historical take (s 17). That administrative flexibility can be used to tighten entitlements in response to increased take or non-compliance.

• Monitoring-triggered review: The monitoring requirements (s 23) create a feedback loop: monitoring data may prompt Ministerial or chief executive review and subsequent enforcement action, and s 27 sets triggers for amendment or replacement of the plan where outcomes are not being achieved.

Limitations and gaps in the plan text

• Absence of specific penalty schedules: The plan does not include specific infringement fines, criminal offences or explicit enforcement procedures; those instruments sit outside the plan text. For a full compliance risk analysis, practitioners must refer to the principal Act and the relevant resource operations plan for specifics on offences, penalty amounts, revocation powers, and administrative remedies.

• Discretion and evidentiary requirements: The plan allows the chief executive to require engineer certification about works capacity (s 17(3)). The exercise of such discretion introduces evidentiary burdens and potential enforcement outcomes if certification reveals non-compliant capacity or actual take rates. The plan therefore creates indirect enforcement leverage through information and certification requirements.

Conclusion on enforcement: The plan establishes the substantive allocation and prohibition rules, and creates monitoring and administrative pathways to detect and respond to breaches, but it does not itself set out penalty provisions. Enforcement of the plan’s requirements is intended to be exercised through licences, conditions and the enforcement provisions of the underlying Act and the resource operations plan, augmented by monitoring and certification powers provided to the chief executive (ss 16-17, 23).

The plan is expressly designed to operate in tandem with the principal Act, the resource operations plan, the Environmental Protection Act 1994 and planning instruments, reflecting multiple points of statutory interaction.

Interaction with the principal Act and resource operations plan

• Delegation of implementation and licensing functions to the resource operations plan: The plan prescribes that operational matters such as making unallocated water available, measurement standards, monitoring requirements, and licence conversions are to be handled under the resource operations plan and the Act (see ss 16-17, 20, 23, 25). Section 16 explicitly invokes s 212 of the Act as the mechanism to grant water licences to replace s 15 authorities. Section 11(3)(f) exempts from the no-increase rule decisions required by the resource operations plan. Therefore, the resource operations plan is the primary instrument for implementation detail and must be read with the Act to understand the full legal effect.

Interaction with Environmental Protection Act 1994 and planning law

• Environmental approvals as exceptions to overland flow prohibition: Section 13(1)(e) permits taking overland flow water of not more than the amount necessary to satisfy an environmental authority issued under the Environmental Protection Act 1994 or a development permit for carrying out an environmentally relevant activity (other than mining or petroleum) under the Environmental Protection Act 1994. Those approvals therefore interact with the plan by creating narrow statutory exceptions for authorised environmental or development activities.

• Reference to the Planning Regulation 2017: Section 14 directs decision-makers to the Planning Regulation 2017, schedule 7, section 5 and schedule 10, section 29 for how the Planning Act regulates operational work involving taking overland flow water. This cross-reference ensures that planning regulation dealing with operational work sits alongside the plan and that applicants must satisfy both planning and water allocation regimes.

Interaction with mining and petroleum regulation

• Specific exceptions and exclusions: Section 13 contains carve-outs that disallow certain environmental approvals for mining and petroleum activities from the particular development-permit exception in s 13(1)(e). Conversely, s 13(1)(f) allows diversion of overland flow water necessary to divert the water around a mine site. The plan therefore treats mining and petroleum activities as special cases that interact with both planning and environmental approvals in limited ways.

Interaction with cultural and Aboriginal interests

• Consideration duties: The chief executive, when dealing with unallocated water, must consider cultural values including local Aboriginal cultural values (s 21(1)(c)(ix)). This does not create a standalone veto right for cultural stakeholders, but it embeds statutorily required consideration which must be evidenced in decision-making records.

Interaction with measurement and engineering certification regimes

• Professional certification: The chief executive may require an authority or licence holder to give a certificate from a registered professional engineer stating information about the works, including capacity and the rate at which the works may take water (s 17(3)). That requirement links the plan to professional regulation and technical standards for engineers and creates compliance-driven information flows between private holders and administrative regulators.

Interaction with the Sustainable Planning Act 2009 and its successor instruments

• Section 18 signals a relationship with the Sustainable Planning Act 2009 and contains amendment notes indicating subsequent legislative change, with omissive notation for later amendments. Section 14 also cross-references the Planning Regulation 2017. Practitioners must therefore read the plan alongside contemporary planning laws and regulations to ensure compliant operational works approvals.

What the plan does not do in terms of other laws

• The plan does not amend the Environmental Protection Act or the Planning Act. It instead sets allocation and procedural rules that apply in addition to (and in some places conditioned by) environmental and planning approvals. It reserves detailed enforcement and penalty regimes to the principal Act and to the resource operations plan.

Practical implication

• To understand the full regulatory effect on a project or operation, lawyers and compliance officers will need to map the plan’s allocation and overland flow rules against the Act’s enforcement powers, the resource operations plan’s procedural rules and monitoring standards, the Environmental Protection Act’s environmental authorities, and the Planning Act and its regulations governing operational work (ss 13, 14, 16-17, 20, 23).

In short, the plan operates as an allocation-layer that must be read in combination with the principal Act, the resource operations plan, planning and environmental law, professional certification obligations for engineers, and monitoring/reporting regimes.

The text includes internal amendment notes that reflect subsequent statutory editing and reform. The plan itself contains explicit amendment annotations which identify legislative updates and consequential changes in cross-references. The following records and implications appear directly from the instrument.

• 2009 amendments: Sections 14 and 18 include amendment notes showing that s 14 was amended by 2009 subordinate legislation (SL No. 280 s 162) and that s 18 was amended (s 163). The amendment to s 14 references both the Planning Regulation 2017 and earlier amendments, indicating the plan’s cross-references to planning regulation have been updated. The amendment notes in the text evidence that s 14(1) was clarified to include a reference to the Planning Regulation 2017, schedule 7, s 5 and schedule 10, s 29; the note appears adjacent to the operative text in the plan.

• 2011 and later amendments: Section 18 carries a later note (2011 Act No. 40 s 107 sch). The plan also contains a note that section 22 was omitted in 2014 (s 22 om 2014 SL No. 142 s 56) and cross-references multiple amendment instruments. Section 11 records an amendment note to s 1 sub 2014 Act No. 64 s 255 sch 2 in the short title area earlier in the plan. The plan carries an omissive note for s 24 that it was substituted in 2014 subordinate legislation (s 24 sub 2014 SL No. 142 s 57) and another omissive note indicating omission in 2016 (om 2016 SL No. 216 s 146 sch 20).

• 2013 amendment to s 13: A note in s 13 indicates amendment in 2013 (2013 Act No. 23 s 352 sch 1 pt 2), and the operative text shows the current form of s 13 including the 5 ML works capacity rule and the exclusions for connected works, as well as updated definitions for ponded pasture and water spreading. The presence of that amendment note shows that the treatment of overland flow and works capacity was reworked in 2013.

• 2014 and 2016 amendments: Several sections carry annotations stating they were substituted or omitted by 2014 and 2016 subordinate legislation, including ss 22 and 24, and s 18 indicates amendment. Section 26 was amended in 2014 (s 26 amd 2014 SL No. 142 s 58), updating the list of types of minor amendments permitted. Section 27 was amended in 2016 (s 27 amd 2016 SL No. 216 s 146 sch 20), altering the triggers for the Minister to consider amending or replacing the plan.

• Consequential and technical changes: Multiple subsections display repeated text blocks with amendment notes and slightly different formatting. These duplication blocks likely reflect statutory drafting systems that include substituted text and annotations. For practical application, one must consult the consolidated and current version as maintained by the department or official legislative database to ensure operative wording.

Implications for practitioners

• The plan has been subject to iterative amendment, especially regarding overland flow rules, measurement and monitoring provisions, and the relationship with planning and environmental instruments. The amendment notes indicate the plan is an actively maintained instrument where cross-references to planning laws and subordinate instruments have been updated.

• Because the plan relies heavily on the resource operations plan and the principal Act, amendments to those instruments or to planning and environmental regulation have consequences for how the plan operates. The 2013 amendment to s 13 modifying the definition of permissible works and imposing a 5 ML capacity limit is a clear example of a substantive policy modification effected by amendment.

• Practitioners should not rely solely on this printed text for current operative detail. They should consult the official consolidated version and the resource operations plan that implements the instrument to ascertain current obligations, permitted works, monitoring requirements and any new or superseding amendment history.

The plan’s amendment notes are the only amendment history contained in the text provided. They point to a pattern of targeted updates over time, particularly in relation to overland flow regulation, measurement/monitoring provisions, and cross-references to planning and environmental law.

The plan text itself does not contain or cite litigation or judicial decisions. There are no cases named or reported within the instrument provided. Consequently, there is no in-text litigation history from which to derive precedent or judicial interpretation. That absence has specific practical implications which follow directly from the instrument’s design.

Direct textual facts

• No cases, tribunals or judicial reviews are mentioned in the plan text. The instrument relies on administrative decision-making by the chief executive, licensing under the Act, and the resource operations plan for implementation (see ss 11, 16-17, 20, 23).

Potential sources of disputes implied by the plan

• Administrative decisions under ss 11, 16-17: Decisions constrained by the plan’s no-increase rule (s 11) and the licence replacement and conditioning powers (ss 16-17) are natural loci for dispute. Applicants and licence holders may challenge the chief executive’s factual assessment of historical take, determinations about works capacity, the imposition of average annual volume conditions, or the refusal or deferment of applications because of the aggregate cap. The plan’s requirement that the chief executive may require engineer certification regarding works capacity (s 17(3)) builds an evidentiary record that will likely be central to any administrative or judicial review.

• Overland flow prohibitions and interpretation of exceptions: Section 13 articulates multiple exceptions for taking overland flow water, including stock and domestic use, works of capacity not more than 5 ML (with exclusions where works are connected to storage), contaminated agricultural runoff, and authorized diversions for mining. Disputes could arise over whether particular works fall within the “works” definition, whether a use qualifies as "contaminated agricultural runoff" as defined by the Code referenced, and whether a proposed take is “necessary” to satisfy an environmental authority or development permit. The plan points to an external Code for the meaning of contaminated agricultural runoff water, and that Code will likely be a focal point for interpretive disputes.

• Unallocated water allocation and caps: The statutory caps on unallocated water,5,500 ML total and 500 ML for town supply absent exceptional circumstances (s 19),create potential for contestation over prioritisation, the chief executive’s assessment of "no other viable water supply," and the evaluation of alternative sources and impacts under s 21. Allocation decisions that deny or cap town supply requests may provoke administrative review or legal challenge if affected parties allege procedural unfairness or misapplication of the required considerations.

• Monitoring and measurement disputes: Licence conditions imposing measurement methods set in the resource operations plan (s 17(4)(d)) and monitoring requirements under s 23 create potential technical disputes where measurement methodology, calibration of devices, or data quality may be contested.

What cannot be said from the text

• The plan does not supply any judicial interpretations or a body of litigation. Therefore it provides no precedent on how courts will construe terms like “necessary” in s 13, “average annual volume” in ss 15-17, or the precise scope of the chief executive’s discretion in s 21. For litigation history, practitioners must search external databases, tribunal records, and judicial decisions arising from decisions under the principal Act and resource operations plans.

Practical approach for risk assessment

• Treat the plan’s decision points as potential litigation hotspots: licence replacements and conditions under ss 16-17, overland flow determinations under ss 13-14, and allocation of unallocated water under ss 19-21.

• Build evidentiary files around historical take and works capacity: the plan explicitly anchors chief executive decisions to estimates of historical take over a period of up to 10 years prior to commencement and allows the chief executive to demand engineer’s certificates (s 12(1)(c), s 17(1)-(3)). Those records will be critical both in administrative decision-making and in any subsequent review.

• Monitor resource operations plan outputs: the resource operations plan will specify operational detail that could be the subject of legal challenge if it materially affects entitlements or imposes measurement and monitoring obligations.

In summary, the plan contains no litigation history in its text. Practitioners should anticipate administrative and possibly judicial disputes centered on historical take assessments, the interpretation of overland flow exceptions, allocation priorities under the unallocated water caps, and technical measurement issues, and should prepare records and technical evidence accordingly.

This instrument contains several technical traps and non-obvious consequences that can affect rights and obligations. Below are concrete “gotchas” grounded in the plan text, with section citations and practical consequences.

1. No-increase rule with many exceptions (s 11)

• The chief executive must not make decisions that increase the total volume that may be taken in the plan area (s 11(1)), but subsection (3) lists multiple exceptions including water permits, reinstatement or replacement of expired licences, certain overland flow taking, grants for pre-2004 stock and domestic works on non-adjoining land, allocations of unallocated water under s 19, and decisions required to be made under the resource operations plan (s 11(3)(a)-(f)). Practitioners should not assume the no-increase rule is absolute. Before relying on the prohibition as a shield, check whether the proposed change fits one of the exceptions.

2. Existing works permitted only with notice and limited to pre-commencement average take (ss 15-16)

• Owners can continue to use existing works for one year after commencement and thereafter only if notice in the approved form and any further information reasonably required are given (s 15(2)-(3)). Failure to file the approved form and supplementary information in time can extinguish the right to continue. Further, the chief executive may grant a water licence replacing that authority and impose conditions to ensure average annual take is not more than that under the pre-commencement operating arrangements (s 16). Parties should preserve historical records of volumes taken, and be prepared to substantiate that continued use will not increase average annual take.

3. Definitions and external instruments control meaning (s 13)

• The plan imports the meaning of “contaminated agricultural runoff water” from a Code for Assessable Development for Operational Works for Taking Overland Flow Water and indicates that a copy of the code is on the department’s website (s 13(2)). This means substantive legal meaning lies in an external document; not consulting that Code may lead to misapplication of the overland flow exceptions.

4. “Works” capacity cap, and connected works exclusion (s 13)

• “Works” are permissible only if having capacity of not more than 5 ML, and explicitly exclude works that are connected physically or by a device to other works used for storing water (s 13(2)). That means a small-capacity storagelike structure that is connected to a larger storage can be treated as part of the larger system and fall outside the s 13 exception. Operators with small works should audit physical connections to avoid falling foul of the exclusion.

5. Irrigation-area licence conversion ceiling (s 12(1)(b))

• For licences expressed in irrigated area rather than volume, the chief executive may convert to volume but not more than 7 ML per hectare. Licence holders should not assume unlimited conversion based on technical irrigation requirements; there is a statutory numerical cap.

6. Unallocated water caps and the town-supply carve-out (s 19)

• The plan caps total unallocated water at 5,500 ML per annum and town supply at 500 ML, but allows the chief executive to authorise more for town supply only where the 500 ML is insufficient and there is no other viable water supply (s 19(1)-(3)). Applicants should prepare to demonstrate insufficiency and lack of alternatives. The chief executive has discretion to allow more, but the threshold is a high administrative hurdle.

7. Monitoring requirements and measurement conditions left to the resource operations plan (ss 17(4)(d), 23)

• While licences may require measurement in the way stated in the resource operations plan (s 17(4)(d)), the plan itself does not state technical measurement standards; those will be in the resource operations plan. Stakeholders should not rely on the absence of technical detail in the plan to contest measurement obligations; the resource operations plan is expected to provide the binding methods.

8. Broad list of matters for unallocated water decisions (s 21)

• The chief executive must consider a long and non-exhaustive list of ecological, social and technical factors when allocating unallocated water (s 21). Applicants should anticipate evidence requests on water quality, habitat connectivity, seasonality, estuarine ecosystem effects, sediment movement, species movement, recreation, cultural values and potential flow conditions to protect low flows. Neglecting to provide such evidence can undermine an application.

9. Possible re-interpretation through resource operations plan and Act procedures (ss 16-20, 25)

• The plan repeatedly ties major implementation points to the resource operations plan and to powers under the Act (e.g., s 16 referencing s 212 of the Act). This means substantive rights and obligations can change in practice when the resource operations plan is drafted or amended. Stakeholders should monitor and engage in the development of the resource operations plan.

10. Ministerial triggers for plan amendment include underground water risks (s 27)

• The Minister must consider amendment where there is a risk that taking or interfering with underground water may significantly impact the plan’s outcomes, including availability for existing entitlements, ecosystem requirements, or water quality, or where the plan’s ecological outcomes are not being achieved (s 27). Parties involved in groundwater or connected surface water projects should note that underground water impacts may prompt plan review, altering the regulatory environment.

These are not abstract risks; they are specific statutory features that can change entitlements, administrative duties, and compliance exposure. Address each of these “gotchas” when assessing projects, licence applications, or compliance strategies.

Compliance under this plan requires aligning operations, documentation and applications with the plan’s substantive limits on take, the overland flow exceptions, the unallocated water caps and the delegated measurement and monitoring rules in the resource operations plan. The following steps are concrete actions grounded in the plan text.

1. Map applicability and verify whether your land or works are inside the plan area

• Confirm whether the land, watercourse, lake or spring concerned is within the plan area as shown in schedule 1. The department holds the exact boundary in digital form and can reduce or enlarge it to show details (s 4, s 5). Use the department’s digital boundary to determine applicability rather than relying on general descriptions.

2. Determine whether the water taken is “water in a watercourse, lake or spring” or “overland flow water”

• The plan applies to both categories (s 6) but treats them differently; overland flow is generally prohibited except for specified exceptions (s 13). Classify the water source early in project scoping.

3. If you have existing works taking overland flow water, comply with s 15 notification requirements promptly

• Owners of land with existing works, other than those allowed under s 13(a)-(g), may continue taking for one year after commencement and thereafter only if they give notice in the approved form and any further information reasonably required by the chief executive (s 15(2)-(3)). Locate the approved form, provide the required information, and retain records of submission. Failure to do so in the one-year window may result in loss of the transitional entitlement.

4. Prepare historical take records and technical evidence

• The chief executive will assess average annual volumes estimated over up to 10 years prior to the plan’s commencement when deciding licence volumes and when replacing s 15 authorities (ss 12(1)(c), 17(1)). Assemble verifiable records of historical take, calibration logs for measurement devices, and any meter data.

5. Anticipate engineer certification if seeking licence replacement or amendment

• The chief executive may require a certificate from a registered professional engineer stating information about the works, including capacity and rate at which works may take water (s 17(3)). Engage an appropriately qualified engineer early to inspect works, quantify capacity, and prepare the certificate if requested.

6. Check whether your proposed works fall within the 5 ML “works” exception or are excluded as connected to other storage

• For overland flow works to be permitted under s 13(1)(b), the works must have a capacity of not more than 5 ML and must not be connected to other storage works or devices that can transfer water (s 13(2)). Physically isolate small works from larger storage systems where appropriate, or be prepared to apply under the resource operations plan process.

7. For licences expressed as irrigated area, use the 7 ML/ha conversion ceiling

• If a licence states the area that may be irrigated, the chief executive will decide the volume required to irrigate efficiently but not more than converting at 7 ML per hectare (s 12(1)(b)). Plan irrigation designs and cropping strategies within that statutory conversion cap.

8. If you require unallocated water, engage with the resource operations plan process and be prepared to supply evidence required by s 21

• Unallocated water allocations are limited to 5,500 ML annually across all purposes, with a 500 ML annual cap for town supply unless greater volume is needed and no viable alternative exists (s 19(1)-(3)). The resource operations plan governs the allocation process (s 20). Prepare evidence on need, existing use efficiency, alternative sources (recycled water, water savings), potential impact on water quality and ecosystems, cultural values, and how proposed flow conditions would protect low flows (s 21). Address these items in applications.

9. Ensure measurement and monitoring systems comply with the resource operations plan

• Licences under the resource operations plan may require measurement methods stated in that plan (s 17(4)(d)). The resource operations plan must also set monitoring requirements to help the Minister assess outcomes (s 23). Establish metering, recordkeeping, calibration regimes, and reporting lines consistent with expected resource operations plan standards.

10. For development or environmental approvals, confirm consistency with s 13 environmental and planning exceptions

• If relying on an environmental authority or development permit to take overland flow water, ensure the amount taken is no more than the amount necessary to satisfy the authority, and be aware that mining and petroleum activities may be excluded from certain exceptions (s 13(1)(e) and (f)). Coordinate with environmental and planning approvals, and cross-reference the Code for contaminated agricultural runoff water if applicable.

11. Plan for possible licence conditions limiting average annual volumes and maximum take rates

• Licences replacing s 15 authorities or granted under the resource operations plan may include maximum volumes, average annual volumes, maximum take rates and measurement conditions (s 17(4)(a)-(d)). Build operational flexibility to adjust extraction rates and install measurement devices to meet potential licence limits.

12. Engage early with the department on the resource operations plan and monitoring regime

• The plan requires preparation of a resource operations plan within three years to make unallocated water available (s 25) and mandates monitoring requirements under s 23. Participate in consultations and supply technical input to influence practical measurement standards and allocation methods.

13. Keep documentation of cultural, environmental and downstream impacts

• The chief executive must consider cultural values and impacts on ecological connectivity, estuarine ecosystems, sediment movement, species movement, recreation and aesthetic values when dealing with unallocated water (s 21). Document assessments, cultural engagement outcomes, and mitigation measures to support applications.

14. Review amendment triggers and be prepared for plan review

• The Minister must consider amending or replacing the plan where authorisations are insufficient for emerging requirements or where underground water risks may significantly affect outcomes (s 27). If your project involves groundwater or could influence underground water, anticipate possible policy or entitlement changes.

15. Maintain regulatory intelligence and legal review

• Because the plan’s operational detail sits largely in the resource operations plan and under the Act, maintain active monitoring of those instruments for changes to measurement methods, penalties, and allocation processes that will affect compliance obligations.

Taken together, complying with the plan requires administrative discipline (timely notices and engineer certificates), technical preparedness (metering and historical usage records), planning alignment with resource operations and environmental approvals, and active participation in the creation and updating of the resource operations plan that operationalises the instrument.
