Agriculture and Related Resources Protection Act 1976

The Act is driven by a small number of statutory concepts and a structured taxonomy that allocates powers and duties according to category and declaration.

• Declared plants and declared animals: The Minister may declare "plants of a class" or "animals of a class" to be declared plants or declared animals (s 35(1)). A declaration must specify geographic extent (whole State or part), whether the declaration is general or in particular circumstances, and the category or categories to which the class is assigned (s 35(2)).

• Categories and statutory meaning of control: Categories determine legal obligations and the scope of control. For plants, P1-P5 have different meanings (s 36(3)); examples include prohibition of introduction/movement (P1), eradication (P2), reduction of numbers or distribution (P3), prevention of spread (P4), and specified actions on public or local government land (P5). For animals, A1-A7 set out prohibitions on introduction (A1), eradication for non‑native vertebrates (A2), prohibition of keeping (A3), regulated introduction (A4), reduction and restriction of numbers (A5), regulated keeping (A6), and management programmes for native animals (A7) (s 36(4)). The definition of control in s 7(1) links each category to duties (e.g. control = destroy, prevent and eradicate for P2/A2; control may include measures approved by an inspector for P3/P4/A5 etc).

• Operational work: Defined in s 57 as acts necessary or conducive to the control of declared plants and animals. Section 58 authorises inspectors and authorised persons to carry out operational work on any place other than a dwelling, and to do so without cost to the owner/occupier (s 58(2A)); funding sources are specified (s 58(2B)).

• Authorised persons and inspectors: The Director General may authorise in writing persons to take measures necessary for control and prevention (s 11(1)); inspectors are appointments under another Act (definition in s 7). Authorised persons must produce written authority if required (s 11(2)).

• Entry and search powers: Inspectors/authorised persons may enter non‑dwellings without warrant to search for declared plants/animals, prohibited material or chemicals (s 84(1)(a), (v)). A justice may grant a warrant for entry into premises excepted from warrantless entry where reasonable grounds exist (s 84(2)). Search and seizure powers extend to vehicles, vessels, aircraft and trains (s 85(1)-(3)), including taking possession of declared plants/animals/prohibited material (s 85(2)).

• Prohibited material: Broad definition in s 7(1) includes declared plants in specified parts of the State and "any packet, parcel, packing material, seeds, soil, vegetable matter or other substance in or with which that plant is packed or associated." That links movement and packaging with enforcement.

• Chemicals: Part VIA s 83A makes it an offence to store, use or transport a "prescribed agricultural chemical" in a prescribed part of the State in a manner not conforming to regulations. Regulations under ss 103-107 and 106A can prohibit or regulate the use of particular chemicals, authorise sampling and seizure, give directions for removal, and provide penalties.

• Regulation‑driven detail: The Act provides high‑level delegations to regulations. Section 105 sets out a range of matters that regulations may cover for declared plants and animals, from control measures to fees, conditions on introductions, regulation of sprays (including by aircraft), recovery of inspection costs, and conditions on permits. Section 107 permits regulations to delegate discretionary authority, create exemptions, apply regionally or sectorally, and prescribe standards or approvals. Section 108 allows penalties under regulations up to $20,000.

• Evidentiary and procedural mechanisms: The Act makes provision for service of notices (s 92), proof of documents (s 93), proof of ownership or occupancy by certificates from registrars or chief executive officers (s 94), proof of plant or animal by Director General certificate (s 94A), and that prosecutions require approval of the Director General (s 98).

• Transitional machinery: Part XI (ss 120-129) preserves approvals, authorisations, declarations and other instruments made before the 2010 amendments, treats them as if given by the contemporary officeholder (Director General or Minister) and provides for transitional regulations where necessary (ss 121-129).

These main concepts interact: declarations determine category; category defines lawful control measures; authorised persons and inspectors execute operational work and exercise entry/search powers; regulations provide the detailed standards, procedures and penalties for chemicals and for many other matters.

The Act affects a range of parties in differing ways. Who pays, who acts, and who decides are central.

• Owners and occupiers of land: The statutory definitions of owner and occupier in s 7(1) are wide, covering freehold estates, Crown lessees, mortgagees, trustees and persons in unauthorised occupation (s 7(1), owner/occupier definitions). Owners and occupiers may be required to control declared plants or animals on their land according to category‑specific obligations (definition of control in s 7(1) and categories in s 36). Notices and orders may be served on owners or occupiers; service rules are in s 92. Where operational work is carried out on private land other than dwellings, s 58(2A) says it may be carried out without cost to owner/occupier, while s 58(2B) identifies funding sources for that operational work.

• Land users with dwellings: Dwellings are treated as a special class for entry‑search powers. Inspectors/authorised persons may not enter a dwelling or dwelling curtilage without a warrant under s 84(2), and a person may apply to the Magistrates Court for review where an enclosed garden or curtilage of a dwelling has been entered and searched (s 84(3)). Operational work is expressly excluded from dwellings in s 58(2A) by the phrase "on and in relation to any place other than a dwelling."

• Persons transporting goods and carriers: Section 85 gives inspectors power to stop and search vehicles, vessels, aircraft and trains to ascertain whether declared plants, animals, prohibited material or chemicals are present. Failure to stop on request is an offence with a $20,000 penalty (s 85(4)). "Prohibited material" includes packaging and seeds and therefore affects shippers, freight handlers and carriers (s 7(1)).

• Owners or keepers of animals: Declared animals may include eggs, semen and immature stages (s 7(1) declared animal definition). Categories A3, A4, A5, A6 and A7 impose potential prohibitions on keeping, conditions on introduction, duties to reduce numbers, and management programmes. Regulations may impose conditions on keeping, sale or disposal and provide for permits, fees and inspections (s 105(t)).

• Businesses that store or handle agricultural chemicals: Part VIA s 83A creates a high fine ($50,000) for storing, using, or transporting prescribed agricultural chemicals in prescribed parts of the State in a manner not conforming to regulations. Regulations (s 106A) may authorise sampling, seizure and directions for removal of chemicals. The definition of "prescribed agricultural chemical" is not in the Act text provided; the Act leaves that for the regulations.

• Contractors, assistants and third parties engaged by authorised persons: Section 84(6) expressly permits authorised persons to employ assistants or contractors, and they have indemnity protection under s 100 unless damage is caused other than in the reasonable exercise of powers.

• The Minister and Director General: The Minister decides declarations (s 35) and assignments of categories (s 36); the Minister may delegate to the Director General (s 10). The Director General makes delegations to officers (s 11A), authorises persons (s 11) and must maintain the public list of declarations (s 37). Prosecutions for offences under the Act require approval of the Director General (s 98).

• Local governments and public authorities: The Act contemplates action on public land and land under local government control (see s 58(2B)(d); s 36(3)(e) for P5 which applies to public land or land under local government control). Regulations may prescribe specific obligations relating to public land and local government administration.

• Persons affected by management programmes: Category A7 for animals contemplates management programmes that the Minister may approve, publish and implement in specified areas (s 36(4)(g)). Those programmes affect owners, occupiers and local stakeholders in the specified area.

• Users of administrative and judicial processes: The Act creates procedural pathways for service, proof and warrants. For example, service by advertisement is permissible where address cannot be found (s 92(1)(d)); a justice may issue a search warrant on sworn evidence by an inspector or authorised person (s 84(2)). Prosecutions must be brought with the Director General's approval (s 98).

Incentives and who bears costs

• Owners/occupiers are exposed to control obligations tied to categories; they may be required to undertake eradication, suppression or other measures (s 7(1) definition of control; s 36). For non‑dwellings, operational work may be carried out at government expense (s 58(2A)-(2B)), shifting direct financial cost to public funds in some circumstances while leaving owners at risk of regulatory action. Regulations may allow recovery of inspection or control expenses from owners/consignors if provided for in regulations (s 105(s)(iii)), so cost exposure can also be shifted to private parties where regulations provide.

• Persons storing, using or transporting prescribed agricultural chemicals in a way contrary to regulations face a substantial fine (s 83A). The Act places regulatory compliance costs on chemical users by forbidding non‑conforming conduct and empowering seizure and directions under regulations (s 106A).

Decision‑makers and discretion

• The Minister holds primary declaratory power (s 35); the Act expressly contemplates the Minister's opinion in assigning categories (s 36(1), (3)-(4)). The Minister may delegate to the Director General; the Director General may further delegate (ss 10, 11A). Regulations may confer discretionary authority on specified persons or bodies (s 107(1)(d)). That structure concentrates critical discretionary decision‑making in the Minister/Director General and their delegates.

This section lists the Act's operational duties on individuals and the rights and protections it creates for subjects of enforcement. Citations identify where duties and rights are created.

Duties imposed on owners, occupiers and handlers

• Duty to control declared plants and animals according to category: The statutory meaning of "control" depends on the category assigned by declaration and creates positive obligations such as destruction, eradication, prevention of spread, or taking prescribed action (s 7(1) definition of control read with s 36(3)-(4)). Where a class is assigned to P2 or A2, control means to destroy, prevent and eradicate those plants or animals (s 7(1)(a)). For other categories, control may include measures approved by an inspector or authorised person (s 7(1)(b)-(f)).

• Duty to comply with regulations regarding prescribed agricultural chemicals: In any prescribed part of the State, a person must not store, use or transport a prescribed agricultural chemical in a manner that does not conform to regulations (s 83A(2)). The offence carries a maximum fine of $50,000 (s 83A(2)).

• Duty to comply with lawful requirements of inspectors and authorised persons: Section 87 makes refusal to comply with any lawful requirement of an inspector or authorised person an offence (s 87(b)), and imposes a maximum fine of $20,000.

• Duty to provide name and address when required: Inspectors or authorised persons may require any person to state their name and address (s 86(a)), and may require an occupier to state the owner's name and address to the best of their knowledge (s 86(b)).

• Duty to stop a vehicle or vessel when required: A person in charge of a vehicle or vessel who fails to stop when required by an inspector or authorised person commits an offence (s 85(4)), with a penalty of $20,000.

• Duty on agents and attorneys to represent absent principals: An attorney or agent who is authorised to manage land represents the principal for purposes of the Act and service on that agent is service on the owner (s 89).

Rights, procedural protections and administrative mechanisms

• Right to require production of written authority: Authorised persons must produce their written authority to the owner or occupier, if required (s 11(2)). That is an express right to verify the authority of the person exercising powers.

• Limit on warrantless entry to dwellings: Inspectors and authorised persons may enter land and premises without a warrant only where those premises are not a dwelling house or a hut, tent, caravan or other erection used as a permanent residence (s 84(1)). For premises excepted from warrantless entry, a justice may grant a warrant on sworn evidence (s 84(2)). Where enclosed garden or curtilage of a dwelling is entered and searched, the owner or occupier may apply to the Magistrates Court for review (s 84(3)). These are statutory checks on warrantless intrusion.

• Indemnity for persons acting under the Act: A person acting in execution of powers under the Act is not to be regarded as a trespasser for so acting and is not liable for damage occasioned by them unless the damage is occasioned otherwise than in the reasonable exercise of those powers (s 100). That is a protection for authorised persons, contractors and assistants.

• Procedural routes for service and proof: The Act prescribes methods by which notices may be served (s 92) including by personal delivery, leaving at last known place, posting, telegram or advertisement where address cannot be discovered (s 92(1)(d)). Certificates from registrars and chief executive officers provide prima facie evidence of ownership or occupancy (s 94(1)(b)); a certificate by or on behalf of the Director General stating a plant or animal is of the kind specified is, until contrary proved, sufficient evidence (s 94A). These provisions structure how affected parties will be notified and how evidence will be established.

• Public information duty: The Director General must maintain and publish a list of declarations and the matters specified in each declaration on the department's website and make copies available at head and regional offices during business hours (s 37). That creates a public right to know which classes are declared and what categories and geographic extents apply.

Administrative controls on enforcement

• Prosecutions require the Director General's approval before commencement (s 98). That centralises decision on committal of prosecutions for offences under the Act.

• Regulations may provide for fees, permits, conditions, exemptions, delegated discretion and penalties up to $20,000 (ss 105, 107, 108). The Act leaves much of the operational detail to the regulations and thereby places a compliance duty on regulated parties to monitor subordinate legislation.

Other duties in delegated instruments

• The Act expressly contemplates that regulations may require actions such as shearing or clipping of animals to remove seed (s 105(s)(i)), inspection, cleansing and disposal of animals or things found to carry prohibited material (s 105(s)(ii)), and recovery of expenses incurred by officers (s 105(s)(iii)). Those are examples of duties that can be imposed by regulation under the Act.

The Act establishes criminal penalties, administrative remedies and procedural controls for enforcement. The statutory enforcement architecture has several key elements.

Penalties defined in the Act

• Chemical misuse in prescribed areas: Section 83A(2) creates an offence for storing, using or transporting a prescribed agricultural chemical in a prescribed part of the State contrary to regulations. The penalty is a fine of $50,000.

• Failure to stop a vehicle or vessel when required: Section 85(4) imposes a maximum penalty of $20,000 on a person in charge of a vehicle or vessel who fails to stop when required by a person who identifies as an inspector or authorised person.

• Obstruction and false statements: Section 87 prescribes a suite of offences , wilfully obstructing, hindering or resisting an inspector or authorised person; refusing or failing to comply with lawful requirements; making false statements or misleading an inspector; assaulting or using abusive language towards an inspector , each attracting a maximum fine of $20,000.

• Personating an officer: Section 88 makes it an offence to falsely represent oneself as, or personate, an inspector or authorised person, with a maximum fine of $20,000.

• Regulatory penalties: Regulations made under the Act may impose penalties of up to $20,000 for breaches (s 108). Regulations may also impose continuing penalties (fine for each separate or further offence under Interpretation Act provisions) up to $500 per additional offence.

Enforcement powers and procedures

• Entry and search: Inspectors or authorised persons may enter non‑dwelling land and premises without warrant for specified purposes including searching for declared plants/animals, prohibited material or chemicals, and for inspection of fences (s 84(1)(a), (b)). For premises that are dwellings or otherwise excepted, a justice may issue a warrant upon sworn evidence of reasonable grounds (s 84(2)). Persons who are entered for such purposes must receive a report of the entry and search signed by the inspector or authorised person (s 84(4)).

• Search of conveyances and seizure: Inspectors and authorised persons may search vehicles, vessels, aircraft and trains to determine presence of declared plants, animals, prohibited material or chemicals contrary to s 83A, and may take possession of any declared plant, declared animal or prohibited material found (s 85(1)-(3)).

• Recovery of expenses and fees via regulations: Section 105(s)(iii) authorises regulations to provide for recovery of expenses incurred by officers in connection with animals, things or prohibited material from owners, consignors, consignees or persons in control. Regulations may also prescribe fees for permits and inspections (s 105(s)(iv)). Those are mechanisms for the State or delegated authority to recoup enforcement costs where regulations so provide.

• Indemnity and civil exposure: Persons acting under the Act are indemnified against trespass claims and civil liability for damage unless the damage was not occasioned in the reasonable exercise of powers (s 100). That reduces risk of civil suits for authorised activity performed reasonably.

Controls on prosecutorial action

• The Director General must approve the commencement of prosecutions for offences under the Act (s 98). That creates an internal administrative control over the institution of criminal proceedings.

Evidentiary aids

• Reports of entry and search by inspectors are prima facie evidence of the matters stated (s 97(2)). Certificates of the Director General identifying a plant or animal are prima facie evidence in proceedings (s 94A). Certificates of registrars provide prima facie proof of ownership/occupancy (s 94(1)(b)). These statutory evidentiary devices streamline proof for enforcement actions and prosecutions.

Delegation of enforcement discretion

• The Minister may delegate his powers or duties to the Director General in writing and may authorise further delegation (s 10). The Director General may delegate to officers (s 11A). Regulations can confer or delegate discretionary authority to specified persons or bodies (s 107(1)(d)). Enforcement discretion is therefore concentrated in executive offices and their delegates.

The Act interfaces with other statutory instruments and administrative frameworks through cross‑references and transitional provisions. The source text provides explicit linkages.

Cross‑references and statutory substitutes

• Biosecurity and Agriculture Management Act 2007: The Act references the Biosecurity and Agriculture Management Act 2007 for the definitions and appointment of inspectors (definition of inspector in s 7(1) and other amendments noted). The compilation notes and amendments indicate consequential changes resulting from the Biosecurity and Agriculture Management (Repeal and Consequential Provisions) Act 2007 (compilation table and notes 1). The Declared Pest Account is defined by reference to that Act (s 7(1) declared pest account).

• Road Traffic (Administration) Act 2008: The definition of "vehicle" is given by reference to the Road Traffic (Administration) Act 2008 s 4 (s 7(1) definition of vehicle).

• Transfer of Land Act and Registration of Deeds Act: Section 92(4) uses registers or records referred to in s 94(1)(b) and contemplates registered powers of attorney under the Transfer of Land Act 1893 or Registration of Deeds Act 1856 for the purpose of service on absent owners.

• Local Government Act 1995: Section 92(1)(c) permits service to an address shown in the rate record kept by a local government under the Local Government Act 1995 as the address for service of rate notices.

Transitional and savings interactions

• Agriculture and Related Resources Protection Amendment Act 2010: Part XI (ss 120-129) contains savings and transitional provisions dealing with approvals, certificates, authorisations, declarations, rates, accounts and management programmes as they were immediately before the 2010 amendments, carrying them forward as if made by the contemporary officeholder (ss 121-126). Section 129 empowers transitional regulations where the Part does not provide sufficient provision.

• Repeal and consequential provisions: The compilation notes show the Act was subject to staged repeal by the Biosecurity and Agriculture Management (Repeal and Consequential Provisions) Act 2007 (note 1) with proclamations fixing different days for different provisions (compilation table and notes). The schedule of amendments and deletions in the text shows significant sections and parts were deleted by later Acts (for example, various deletions noted for Part III, Divisions of Part V, Part VI etc). The Act as compiled must therefore be read alongside the compilation table and Gazette proclamations to identify which provisions are in force at any given time.

Delegation and overlap with administration

• Executive delegation: The Minister may delegate powers to the Director General (s 10). The Director General may delegate to officers (s 11A). That formal delegation structure means functions may be exercised under the Act by departmental officers rather than the Minister personally. Those delegations interact with administrative law principles and with the powers and responsibilities of the department in administering other statutes.

Regulatory interplay

• Regulations under this Act (ss 103-107) may set fees, conditions, standards and prohibitions that interact with licences, permits or conditions imposed under other Acts; for example, regulation of animal introductions and keeping (s 105(t)) may need to be coordinated with wildlife, land use and local government regimes. The Act also expressly contemplates the Director General making use of other administrative processes (s 58(2B)(d) provides for operational work pursuant to an agreement under sections that are indicated to have been deleted; the compilation shows a history of such interactions).

Evidence and procedure across statutes

• Certificates from registrars and chief executive officers of other departments are admissible evidence (s 94(1)(b)(i)-(iv)), thereby incorporating documentary and registration systems from the land and mining statutes, and conservation permit records. That interaction simplifies proof of ownership or occupancy across statutes.

Where the Act leaves detail to subordinate instruments, operators must check the regulations and any relevant instruments made under other Acts to understand the full compliance picture. The Act creates hooks to other instruments rather than fully specifying every regulatory detail in the principal Act.

The compilation table and marginal notes supplied in the text record the Act's amendment and reprint history from 1976 to at least 2015. Key chronological points and consequential mechanical effects in the source text are:

• Original enactment: Agriculture and Related Resources Protection Act 1976 (No. 42 of 1976), assented 9 June 1976, with staged commencement specified in s 2 (compilation table).

• Series of amendment Acts through the 1970s and 1980s: Amendment Acts in 1978, 1979, 1980, 1981 and 1983 altered content; the compilation includes reprints incorporating those amendments (e.g. reprint approved 10 Feb 1981, reprint as at 15 Oct 1999).

• 1984-2006 amendments and machinery of government changes: Amendments and consequential changes from statutes such as the Acts Amendment (Conservation and Land Management) Act 1984; Taxation Administration (Consequential Provisions) Act 2002; Statutes (Repeals and Minor Amendments) Act 2003; Courts Legislation Amendment and Repeal Act 2004; and Machinery of Government (Miscellaneous Amendments) Act 2006 are recorded in the compilation table and marginal notes. These changes included deletions and insertions to various provisions and procedural updates.

• Biosecurity and Agriculture Management (Repeal and Consequential Provisions) Act 2007: The compilation notes that s 27 of that Act provided for repeal of the Agriculture and Related Resources Protection Act 1976 on a day fixed by proclamation (note 1). The compilation table records proclamations repealing provisions on various dates (Gazette entries 5 Feb 2013 p. 824 and 4 Jul 2014 p. 2359). The main text also identifies many deletions made by No. 24 of 2007 in marginal notes (for example, Parts and sections deleted by No. 24 of 2007 s 27). Those repeals and consequential amendments materially changed the Act's footprint.

• Agriculture and Related Resources Protection Amendment Act 2010 (No. 46 of 2010): Inserted key delegation provisions (s 10 and s 11A), introduced Part XI (s 120 onwards) containing savings and transitional provisions, and effected other amendments (noted in the Act text as insertions and amendments). The commencement date for this Act's relevant parts is listed as 18 December 2010 (compilation table).

• Later amendments and reprints: Other items such as the Road Traffic Legislation Amendment Act 2012 (Pt 4 Div 1) have amendments listed, with dates of commencement for those amendments recorded in the compilation table (e.g. 27 Apr 2015). Reprints as at 16 June 2006 and 17 Oct 2014 are noted.

• Deletions and restructuring: The text shows several substantial deletions over time. For example, Part III (ss 13-16) and several divisions of Part V and Part VI were deleted by No. 46 of 2010 and No. 24 of 2007, as indicated in the Act text margins. Those deletions removed earlier procedural or substantive material, leaving the current Act concentrated on the declaration regime, entry/search powers, operational work and chemical regulation.

Transitional provisions

• Part XI (ss 120-129) implements transitional mechanics for the 2010 Amendment Act: it preserves existing approvals, certificates, authorisations and declarations by treating them as if given by the Director General or Minister after commencement (ss 121-123); it addresses rates, funds and the Declared Pest Account (ss 124-125); preserves management programmes (s 126); carries forward notices, permissions and authorities (ss 127-128); and authorises transitional regulations (s 129). Those provisions indicate how instruments in force immediately before changes continue to operate.

Practical consequence for users: because the Act has been amended and partially repealed across multiple statutes and proclamations, the operative content must be read against the compilation table and Gazette proclamations to determine which provisions remain in force at any date. The Act itself incorporates many marginal notes recording deletions and amendments; the Part XI transitional machinery preserves instruments made before the 2010 amendments.

The source text contains no reported case law or judicial decisions. It does, however, include procedural and evidentiary measures that structure litigation and administrative review:

• Judicial warrants and review: A justice may grant a warrant authorising entry and search of premises otherwise excepted from warrantless entry where reasonable grounds are made out on oath or affirmation by an inspector or authorised person (s 84(2)). Where the enclosed garden or curtilage of a dwelling house is entered and searched under this section, the owner or occupier may apply to the Magistrates Court for a review of the exercise of that power on the grounds that there were no reasonable grounds (s 84(3)). Those provisions create a judicial oversight pathway for certain intrusions.

• Evidentiary devices likely to be relied upon in prosecutions: Reports drawn up and signed by inspectors after entry and search are prima facie evidence of the matters stated (s 97(2)); certificates by the Director General stating that a plant or animal is of a specified kind are sufficient evidence until contrary is proved (s 94A); certificates by registrars provide prima facie proof of ownership or occupancy (s 94(1)(b)). Those devices will shape the evidentiary posture of prosecutions.

• Prosecution initiation control: Section 98 requires that a prosecution for an offence under the Act cannot be commenced except by or with the approval of the Director General. That procedural rule affects the pattern of litigation by controlling which matters proceed to court.

Because the source text contains no case citations or a schedule of judicial decisions, the compilation provides no examples of judicial interpretation of the Act's key phrases, such as the scope of "control" for different categories, reasonable exercise of powers for indemnity purposes, or the limits of warrantless entry. Practitioners will therefore need to check contemporary case law and administrative decisions outside this source to assess judicial views on contested points. The Act's own procedural provisions, however, anticipate judicial involvement in warrant issuance and limited review by the Magistrates Court in the dwelling curtilage context.

The Act contains several features that practitioners, owners and businesses should note because they create points of friction, potential exposure or compliance traps.

1. Wide discretion in declarations and category assignment: The Minister decides which classes are declared and assigns categories based on the Minister's opinion of what measures are necessary to achieve the Act's object (s 35(1)-(2); s 36(1)-(2)). That concentrates decision‑making in a political and administrative office; legal consequences flow from category assignment because the statutory meaning of "control" is category‑dependent (s 7(1), s 36). The choice of category transforms legal duties , for example, P2/A2 require eradication (s 7(1)(a)).

2. Broad warrantless entry to non‑dwellings: Inspectors and authorised persons may enter land and premises which are not dwellings without a warrant "at any time" for specified purposes including to ascertain presence of declared plants/animals and chemicals (s 84(1)). That creates a low threshold for intrusion into commercial or agricultural premises that are not dwellings. Dwellings and curtilage are protected from warrantless entry but can be entered with a justice's warrant on sworn evidence of reasonable grounds (s 84(2)); the owner or occupier may seek review (s 84(3)).

3. Operational work may be carried out without cost to owner or occupier for non‑dwellings: Section 58(2A) authorises operational work on any place other than a dwelling without cost to owners/occupiers. Funding is provided by parliamentary appropriation or the Declared Pest Account, or by arrangements for pastoral lease land (s 58(2B)). That removes a private cost barrier but may also mean state action on private land without owner consent (subject to entry/search powers); owners should be aware of potential operational work and associated interventions.

4. Prohibited material is defined to include packaging and seeds: The definition of "prohibited material" (s 7(1)) extends to packets, packing material, seeds, soil, vegetable matter or other substances in or with which a declared plant is packed or associated. Transporters, exporters and importers may inadvertently carry prohibited material and be subject to inspection, seizure and disposal powers (s 85(1)-(3); s 105(s)(ii)).

5. Director General's certificate as prima facie evidence: In prosecutions, a certificate signed by or on behalf of the Director General that a plant or animal is of a specified kind is sufficient evidence until contrary proved (s 94A). That evidentiary device shifts the evidentiary burden to defendants to rebut identification claims.

6. Prosecutions require Director General approval: Section 98 mandates that prosecutions cannot be commenced except by or with the approval of the Director General. That can concentrate discretion to prosecute in one official and may affect the patterns and timeliness of enforcement.

7. Large statutory penalties and regulation‑driven additional penalties: Section 83A prescribes a maximum fine of $50,000 for non‑conforming chemical storage/use/transport in prescribed parts of the State. Other statutory offences carry $20,000 maximum fines (ss 85(4), 87, 88), and regulations may impose penalties up to $20,000 (s 108). Entities in the supply chain for chemicals and declared plants/animals face significant monetary exposure.

8. Regulations may confer discretionary authority and create new obligations: Section 107(1)(d) permits regulations to confer or delegate discretionary authority to specified persons or bodies. Section 105 enumerates many matters regulations may cover including permits, fees, conditions on introductions, and recovery of enforcement expenses (s 105(s)). Practitioners must monitor subordinate instruments closely because much operational detail and liability is regulated.

9. Deletions and transitional complexity: The Act has undergone multiple deletions and amendments; parts of the original Act were repealed and replaced by the Biosecurity and Agriculture Management Act 2007 and later instruments (compilation notes and table). Transitional provisions in Part XI preserve some instruments, but the precise operative text depends on which provisions have been commenced or repealed by later proclamations. Users must check the compilation table and Gazette proclamations to determine current law for particular sections.

10. Indemnity for authorised persons may limit civil remedies but not bad‑faith liability: Section 100 protects persons acting under the Act from being regarded as trespassers and from liability unless damage is caused otherwise than in the reasonable exercise of powers. That reduces civil exposure for good‑faith authorised actions but does not absolve wrongful, unreasonable or malicious conduct.

11. Public list obligation: The Director General must maintain a list of declarations on the department website and make copies available at head and regional offices (s 37). However, the Act does not shift onus from regulated parties to the department; parties cannot assume ignorance of declarations will be accepted as a defence because the list is publicly accessible.

12. Broad scope of "declared animal" and "declared plant": Declared animal includes egg or semen and immature stages and, unless otherwise specified, hybrids and crosses (s 7(1)). Declared plant includes parts and products (s 7(1)). That broad scope can capture biological materials not commonly thought of as the animal or plant, for instance semen or seed products.

These points are not legal conclusions but are mechanical and operational features of the Act that affect compliance strategies and enforcement risk.

This section sets out concrete steps and organisational practices that owners, occupiers, transporters, chemical handlers and advisers should adopt to align with the Act's statutory duties and to manage exposure under the Act as it reads.

1. Maintain awareness of declarations and categories

• Check the Director General's publicly accessible list of declarations on the department website and obtain copies at head/regional offices where needed (s 37). The list must set out every class of plants or animals that is currently declared and the matters specified in s 35(2). Because category assignment determines control obligations (s 36; s 7(1) control definition), ensure you know whether a species is declared and which category applies in your area.

2. Map obligations to category definitions

• For each declared class present on or near your land or business, read the statutory meaning of control applicable to that category (s 7(1) and s 36). For example, P2 and A2 require destruction, prevention and eradication (s 7(1)(a)). P3/P4/A5 permit measures as approved by an inspector or authorised person (s 7(1)(b), (c), (e)). For A7, check whether a management programme applies in your area and the management programme's published requirements (s 36(4)(g); s 126 as to preserved management programmes).

3. Comply with regulations on chemicals and seek clarity on "prescribed" definitions

• Section 83A makes it an offence to store, use or transport a prescribed agricultural chemical in a way that does not conform to regulations in prescribed parts of the State, with a fine of $50,000 (s 83A(2)). Identify the applicable regulations and any prescribed parts of the State. Ensure storage, transport and use procedures, staff training and record keeping conform to those regulations. The Act gives regulators authority to sample, seize and direct removal of chemicals (s 106A).

4. Permit and record management

• If you keep or intend to introduce animals that might be in categories A4 or A6, familiarise yourself with permit regimes that regulations may create (s 105(t)). Keep records of permits, inspections and any conditions attached by the Director General or authorised officers.

5. Respond to inspectors and authorised persons promptly and lawfully

• Ensure staff know to stop vehicles or vessels when required by an inspector and to produce driver details or other required information (s 85(4), s 86). Do not obstruct or mislead inspectors; s 87 creates a criminal offence for obstruction or false statements with a $20,000 penalty.

• If approached by an authorised person, request production of written authority where appropriate (s 11(2)) and document interactions. Retain copies of any orders, notices or directions given. Signed reports of entry/search by inspectors are prima facie evidence in proceedings (s 97(2)).

6. Prepare for potential operational work on non‑dwellings

• Because operational work may be carried out on places other than dwellings without cost to the owner/occupier (s 58(2A)) and may be funded from public moneys or the Declared Pest Account (s 58(2B)), owners of non‑dwelling agricultural land should anticipate the possibility of state‑initiated control measures. Keep inventories of sensitive areas, biosecurity measures and contact points to coordinate with inspectors and mitigate disruption.

7. Protect dwellings and curtilage rights

• Know that dwellings and their enclosed gardens have special protection: warrantless entry is not permitted (s 84(1)), and entry to dwellings requires a warrant granted by a justice on sworn evidence of reasonable grounds (s 84(2)). Owners/occupiers whose dwelling curtilage has been entered and searched may apply for Magistrates Court review on the ground there were no reasonable grounds (s 84(3)). Keep records and photographs of any entry to support any review.

8. Ensure transporters and packers manage prohibited material

• As "prohibited material" includes seeds, soil, packing material and other associated substances (s 7(1)), carriers and packers should implement cleaning, inspection and segregation protocols to avoid carrying declared plants or prohibited material. Inspections and seizure powers extend to vehicles and rail (s 85).

9. Document property rights, trust and agency arrangements

• Ensure powers of attorney and agency arrangements that authorise management are properly documented and, if applicable, filed or enrolled under the Transfer of Land Act or Registration of Deeds Act as required for service rules (s 92(4)). Agents authorised to act for absent owners are deemed to represent their principals for service and notice purposes (s 89).

10. Manage legal risk and evidence

• Obtain independent technical identification of plants and animals where there is any dispute but note a Director General's certificate is prima facie evidence in prosecutions (s 94A). Retain copies of any certificates, permits, notices and correspondence. Where a prosecution is contemplated, expect that the Director General's approval is required before a prosecution is commenced (s 98).

11. Monitor subordinate instruments and local regulations

• Because much of the operational detail is left to regulations (ss 103-107, 106A), maintain a compliance tracker for regulations, local orders, permits and management programmes relevant to your operations. Regulations may prescribe fees, require statutory declarations, create exemptions, delegate discretion and impose penalties (s 107(1)(c)-(f); s 108).

12. Engage early with the department for dispute avoidance

• Where there is uncertainty about the category assignment, permitted measures or proposed operational work, engage with the Director General's office or authorised persons to clarify expectations and, where appropriate, negotiate agreements for operational work on private land (s 58(2B)(d) contemplates actions pursuant to agreements).

13. Budget for potential recovery of expenses where regulations provide

• Regulations may authorise recovery of expenses incurred by officers in dealing with animals, things or prohibited material from owners, consignors, consignees or persons in control (s 105(s)(iii)). Businesses should budget for such potential exposures if regulations in force in their sector permit cost recovery.

14. Train staff to verify authority and to document interactions

• Employees should be trained to request written authority from authorised persons (s 11(2)), to comply with lawful requirements, to record identity and reasons for inspections, and to avoid obstructive conduct (s 87). Maintain a protocol for responding to inspection requests and for escalating disputes to legal counsel or departmental contacts.

By following these steps and aligning internal policies with the statutory definitions and categories (s 7 and s 36), regulated parties can reduce enforcement risk and be in a position to rebut prima facie evidence where necessary. Regular review of the department's published list of declarations (s 37) and of regulations made under the Act is essential because the operational detail and liability exposure is largely regulation‑driven.
