Biosecurity and Agriculture Management Act 2007

The Act frames biosecurity and agricultural management around a set of definitional and structural concepts that determine who decides, who pays and what behaviour is regulated.

Organism classification and declarations. The Act distinguishes permitted organisms (Ministerial declaration, s 11), prohibited organisms (Ministerial declaration subject to reasonable grounds, s 12) and unlisted organisms (s 14). Prohibited organisms are declared pests for the whole State by operation of law (s 22(1)); other declared pests are declared for specified areas (s 22(2)). A declaration may assign categories (s 22(3)), and declarations must be published (s 157). These instruments concentrate decision‑making in the Minister (ss 11-13, 22) while requiring consultation obligations.

Import control and potential carriers. Importation is controlled by s 15: prohibited and unlisted organisms require import permits and compliance with regulations, and prescribed potential carriers are also regulated. The Act defines potential carrier broadly (s 6) and allows the regulations to prescribe which carriers or carrier classes are regulated (s 15(3)). Commercial carriers and passenger carriers have specific procedural obligations (ss 19-20). Failure to comply carries significant criminal and monetary penalties (s 15 and elsewhere).

Notices, directions and compulsory measures. The Act gives administrative tools to manage risks on land and goods: pest exclusion notices (s 27), pest control notices (s 31), pest keeping notices (s 35), residue management notices (s 52) and Director General notices (ss 43, 44, 79). Inspectors can give directions (s 77), seize and detain things (s 73), and require movement for treatment (s 76). The Director General can take remedial action and recover costs (ss 94, 38, 87) and secure recovery by registering a charge on land (s 95).

Inspection and evidence architecture. Inspectors are appointed by the Director General (s 162). For inspection purposes they have broad powers of entry, search, sampling, seizure and to obtain or operate records and computers (ss 65, 66). The Act includes detailed evidentiary presumptions and admissibility rules for analysis reports, certified copies of documents, and evidence of organism classification and place of offence (Part 5 Div 3, ss 113-124). The Act also provides for SAT review of many administrative actions, subject to regulatory exceptions for emergencies (numerous sections cross‑referenced above).

Financial instruments and levies. The Act establishes a Declared Pest Account funded by Ministerially determined rates on land in prescribed areas (ss 129-139). It sets upper limits on ad valorem rates (s 132), provides for pensioner postponement (s 136) and applies parts of the Taxation Administration Act 2003 and Land Tax Assessment Act 2002 to rates collection (s 135). It also allows the Governor to create industry funding schemes, prescribed accounts and management committees by regulation (ss 141-146). The Modified Penalties Revenue Account receives infringement payments and funds enforcement and awareness (ss 148-149).

Delegated legislation and codes. The Act enables extensive subordinate law making: regulations (s 188) may cover the matters listed in Schedule 1; management plans issued by the Minister are subsidiary legislation subject to disallowance (s 47); codes of practice may be issued or approved under s 191 and may be incorporated into regulations (s 190). The power to adopt external codes or subsidiary legislation by reference (s 190) means regulatory detail can be drawn from other jurisdictions or standards unless the regulations fix a particular text.

Rights, administrative review and civil remedies. The Act provides multiple administrative review routes: internal review by the Director General (s 36(1)-(5)) and external review by the SAT for many classes of decision (ss 28, 34, 37, 74, 75, 78, 80, 83, 86), while permitting regulations to limit review rights in emergency circumstances. The Director General may seek injunctions in the courts (s 109). The Act also contemplates civil recovery mechanisms and ancillary court orders on conviction (ss 106, 98). Officials acting in good faith are immunised from tortious liability (s 187).

Standards and contamination. The Act defines contamination in relation to maximum residue limits and allows the regulations to set those limits (s 7; Schedule 1 item 30). Residue management notices (s 52) and prohibitions on dealing with contaminated products (s 57) operationalise those standards, with registration and notification powers associated with land documents (s 55, Part 4 Div 7).

Taken together, these concepts allocate rights to decide (Minister and Director General), operational powers to inspectors and the department, and costs to landowners, importers, carriers, producers and industry through compliance duties, rates and possible recovery of remedial action costs.

Immediate parties with statutory obligations. The Act imposes duties on a wide array of private and public actors. Owners and occupiers of land are repeatedly specified as recipients of notices and the persons required to take action in respect of declared pests and residue management (see ss 27, 31, 30, 52). Importers, consignors, consignees and other persons in control of organisms, potential carriers or contaminated goods face import‑permit and notification duties (ss 15-16, 21, 82). Commercial passenger carriers and other commercial carriers have specific obligations to give information and provide facilities (s 19) and to notify the Director General for consignments when required (s 20). Persons who supply or possess imported unlawful organisms commit offences where they know or ought reasonably to know of the contravention (ss 17-18).

Industry groups, producers and management committees. Regulations may establish prescribed accounts and industry funding schemes with management committees drawn from producers and persons with financial interests (s 141). These bodies may collect contributions (s 144) and administer compensation or control programs (s 145). Recognised biosecurity groups may receive transfers from the Declared Pest Account subject to written directions and reporting (ss 169-170).

Public authorities and advisory bodies. The Minister and the Director General exercise central decision‑making powers: declarations of organism status (ss 11-12, 22), issuing management plans (s 45), issuing codes of practice (s 191), and directing remedial action (ss 38, 94). The Biosecurity Council is an advisory body with functions to advise Minister and Director General (ss 48-50). Local governments may make local laws for pest plants in their districts (s 193) and may render assistance to owners/occupiers (s 41).

Service providers and third parties. The Authority (ss 150-156) and the department (through inspectors) exercise operational functions, including entering into agreements for quarantine facilities, provision of services, and deployment of inspectors. Persons involved in the supply, manufacture, handling, storage or advisory services for chemical products, animal feed and fertilisers are specifically regulated (s 56, Schedule 1 items 22, 26-28). Veterinarians and pharmacists (as veterinary chemical preparers in defined circumstances) are included within the Act’s regulatory ambit (see definitions in s 6).

Land title and finance stakeholders. The Act permits the Director General to lodge notifications or memorials in the Land Titles Register in respect of residue management notices and charges for remedial action (ss 55, 95, 101). Mortgagees and purchasers will be affected by those memorials (s 103), and the Act prescribes the priority of such charges (s 96). The Commissioner (Taxation Administration Act) collects the rates determined by the Minister for the Declared Pest Account (ss 130, 133, 135).

Third‑party liability and vicarious responsibility. Officers of corporations, principals and employers can be charged for offences by bodies corporate, agents or employees (ss 110-112). The Act therefore creates compliance exposure that extends beyond the individual who directly commits an offence to corporate officers, principals and employers unless specific defences are proved.

General public and business markets. The Act criminalises, with substantial penalties, acts that cause public alarm or economic loss by adulteration, threats to adulterate or false statements about adulteration (ss 60-62). The Act also affects commercial terms: agreements purporting to exclude the Act’s application in relation to chemical treatment of agricultural product are void (s 58), and purchasers retain remedies. Quality assurance schemes and labelling obligations (Schedule 1 items 32-36) link statutory regulation to product markets and private contracting.

In short, the Act’s reach is broad: primary producers, landowners, importers and carriers, chemical suppliers and advisers, industry management committees, local governments, mortgagees and purchasers of land, public authorities, officers of corporations, and recognised biosecurity or advisory groups all face defined duties, obligations and possible liabilities under the Act.

Duties created by the Act are numerous and can be grouped by activity type.

Importation and supply duties. Persons must not import prohibited or unlisted organisms except in accordance with an import permit and the regulations (s 15(1)-(2)). Supplying or possessing organisms or potential carriers imported in contravention of s 15 is an offence where the person knows or ought reasonably to know of the contravention (ss 17-18). Importers must give notice of intended entries where regulations require it and present consignments to inspectors when required (s 21). Commercial carriers and passenger carriers have prescribed duties to inform passengers and to provide secure deposit facilities (s 19).

Duties to report and control. Persons who find or suspect declared pests in an area where an organism is a declared pest must report to the Director General or an inspector (s 26). Owners/occupiers or persons in control of infected or infested organisms must take prescribed control measures under regulations or management plans (s 30(2)-(3)). Where more than one person is required to act, compliance by another person can be a defence (s 30(5)); ignorance is a defence where the person could not reasonably have been expected to know (s 30(6)).

Compliance with notices and directions. The Director General or an inspector may issue pest exclusion, pest control and pest keeping notices requiring specific measures (ss 27, 31, 35). A person to whom a notice is given must comply (s 29, s 32). Inspectors also have power to direct owners, consignors, consignees or persons in control to move organisms or potential carriers for treatment, to treat or destroy things, and to give information and assistance during inspections (ss 76-77, 66-67). Failure to comply can lead to fines and remedial action (s 38, s 87).

Inspection and record‑keeping duties. Inspectors may obtain records, direct operation of computers, seize and make copies, and require translations or passwords where relevant (s 66). The regulations may require qualifications, notifications, standards of handling and record-keeping in relation to chemical products and animal feed (s 56; Schedule 1 items 26-28, 30). The Act makes non‑compliance with such regulatory duties an offence with fines (s 56).

Residue and contamination duties. The Director General may give residue management notices where land contains levels of chemical products likely to cause agricultural products to exceed maximum residue limits (s 52). The notice can restrict use and require approval before certain uses (s 52(3)); residue notices bind successive owners if registered with Title (s 52(6), s 55). The regulations prescribe maximum residue limits (Schedule 1 item 30) and the concept of contamination is defined in s 7.

Financial duties. Owners of land in prescribed areas may be subject to rates determined by Ministerial notice for the Declared Pest Account (ss 130-133). Rate determinations are subject to consultation (s 131) and limits set by s 132. The Declared Pest Account is credited with rates, appropriations and other receipts and funds pest control activities (ss 137-138). Contribution schemes for prescribed sectors may impose contribution duties under regulations (ss 141-146).

Rights of review and procedural protections. The Act provides internal review by the Director General for pest control and pest keeping notices (s 36). Numerous decisions are reviewable by the State Administrative Tribunal, including seizure, forfeiture and various notice decisions, subject to regulations that may exclude review in emergencies (see ss 28, 34, 37, 74, 75, 78, 80, 83, 86). Directions may be given orally but must be confirmed in writing within five working days (s 89(2)). Where a person objects on self‑incrimination grounds, the Act permits compelled disclosure but makes the compelled information inadmissible except for perjury or false/misleading information prosecutions (s 93). The Act also provides evidentiary presumptions favourable to the administration (Part 5 Div 3).

Liability and vicarious exposure. Corporate officers, principals and employers can be charged in relation to offences committed by corporations, agents or employees (ss 110-112). This expands the exposure profile and creates incentives for entities to adopt compliance systems.

Administrative discretion and delegation. The Minister has broad regulation, declaration and management plan powers (ss 11-12, 22, 45, 188-191). Powers may be delegated to the Director General or departmental officers (ss 181-182). The Director General has discretion to take remedial action and recover costs (ss 94-95), and to authorise urgent inspector action (s 43).

In sum, the Act combines duties to prevent, report, control and not move declared pests or contaminated goods with significant enforcement tools and some procedural safeguards including internal and SAT review routes. Rights are mostly administrative and procedural rather than substantive property rights.

The Act layers criminal, administrative and civil enforcement mechanisms. Key penalty figures and enforcement tools are as follows.

Monetary fines and imprisonment. The Act prescribes a range of criminal penalties, often linked to organism classification and gravity:

• Importing a prohibited organism contrary to s 15(1): fine up to $50,000; if the organism is a high impact organism, fine up to $100,000 and imprisonment up to 12 months (s 15(1)).
• Importing an unlisted organism in contravention of s 15(2): fine up to $20,000 (s 15(2)).
• Importing prescribed potential carriers contrary to s 15(3): fine up to $50,000 or, if the carrier is for a high impact organism, $100,000 and imprisonment 12 months (s 15(3)).
• Supply or possession of unlawful imports where person knows or ought reasonably to know: supply (s 17) penalty up to $50,000 or $100,000 and imprisonment for high impact organisms; possession (s 18) penalty up to $20,000 or $100,000 and imprisonment for high impact organisms.
• Contravening general prohibitions about dealing with declared pests (keeping, breeding, releasing, etc.): fine up to $50,000 or if high impact, $100,000 and imprisonment 12 months (s 23(1)).
• Failure to comply with a pest control notice or pest exclusion notice: fines up to $20,000 (s 29, s 30) or up to $50,000 (s 32) depending on the instrument and whether the organism is high impact (several provisions).
• Adulteration offences (ss 60-62): up to $100,000 and imprisonment for 12 months.
• Obstruction of inspectors or failure to comply with their lawful directions: up to $20,000 (s 92).

Inspectors’ coercive powers. Inspectors may enter, search and take control of places and conveyances for inspection purposes (s 65). They can take samples, photograph, mark out land, label things and take assistants and equipment (s 65(1)). They may obtain, copy and seize records and operate computers (s 66). Inspectors may give directions such as requiring movement to an inspection point, labelling goods and restraining animals (s 67). Where persons do not comply with directions to move consignments or animals, inspectors may do anything necessary, including moving a conveyance (s 67(2)-(3)).

Seizure, treatment and destruction. Inspectors may seize or detain organisms, carriers, agricultural products, chemical products and other things until identification, treatment or disposal is complete (s 73(1)). Seized items may be treated, destroyed, disposed of or declared forfeited subject to regulations and SAT review windows (ss 73(2)-(4), 74-75). Inspectors may direct owners to treat, refrain from treating, destroy or otherwise dispose of things (s 77) and may direct movement for treatment (s 76). The Director General may issue notices requiring owners to treat or destroy organisms brought into the State or an area in contravention of the Act (s 79).

Remedial action and cost recovery. If notices or directions are not complied with, the Director General may take remedial action and recover costs (ss 38, 87, 94). The Act creates a statutory charge on land to secure unpaid remedial costs and sets priority rules for registration and recovery, including the Director General’s ability to exercise mortgagee powers and to prevent dealings with land without consent (ss 95-99). Memorials and withdrawals are administered through the Registrar of Titles (s 101).

Infringement notices and modified penalties. Inspectors may issue infringement notices for prescribed offences within 21 days of the alleged offence (s 126). The notice sets a modified penalty amount and a 28‑day payment window, with the Director General able to withdraw notices and refund payments (ss 126-127). Paid modified penalties are treated as preventing prosecution to the same extent as conviction would (s 128).

Judicial and administrative remedies. The Director General alone (or a person authorised by the Director General) may commence prosecutions (s 104). Courts may make ancillary orders on conviction including orders to notify specified persons, take remedial measures, and pay costs reasonably incurred by the Director General or others in repairing damage (s 106). The Director General may seek injunctions from the Supreme or District Court (s 109). SAT review is available for many inspection and seizure decisions and for notice decisions, subject to regulatory exceptions for emergencies (see the multiple SAT‑review sections referenced earlier).

Immunity and information protections. Officials acting in good faith are immune from tort claims for things done or omitted in the performance or purported performance of functions under the Act (s 187). Compelled information under inspector directions is not admissible against the person in civil or criminal proceedings except for perjury or related offences (s 93).

Evidence and administrative presumptions. The Act includes evidentiary presumptions and recognises approved analyst reports, certified copies of instruments and other administrative evidence to streamline enforcement procedures (Part 5 Div 3, ss 114-124, 119).

Together, the enforcement regime combines criminal sanctions with administrative coercion and cost recovery. Enforcement is designed to be both punitive (fines and imprisonment for severe breaches) and corrective (treatment, destruction, remedial action and charges on land).

The Act is explicitly designed to sit alongside and to be read with a suite of other statutory instruments; the statute both imports terms from and defers to other laws in particular areas. The interaction can be grouped by constitutional and operational linkages.

Statutory read‑together and precedence. Section 4(1) requires the Biosecurity and Agriculture Management Rates and Charges Act 2007, the Land Tax Assessment Act 2002 (to the extent it applies to Part 6 rates), and the Taxation Administration Act 2003 to be read with this Act as if they formed a single Act. Section 4(2) lists statutes whose provisions operate in addition to this Act (for example the Agricultural and Veterinary Chemicals (WA) Act 1995, Animal Welfare Act 2002, Biodiversity Conservation Act 2016, Environmental Protection Act 1986, Exotic Diseases of Animals Act 1993, Public Health Act 2016, Food Act 2008, Medicines and Poisons Act 2014 and Police Act 1892). Where this Act is inconsistent with those Acts (except as provided in s 40(3)), the latter prevails to the extent of inconsistency (s 4(3)).

Imported definitions and cross‑references. The Act imports statutory definitions and cross‑reference concepts: the Agvet Code of Western Australia is defined by reference to the Agricultural and Veterinary Chemicals (Western Australia) Act 1995 (s 6); the meaning of owner in relation to a vehicle or vessel refers to the Road Traffic (Administration) Act 2008 and the Western Australian Marine Act 1982 (s 6); the Authority’s and Director General’s powers must operate consistent with the Financial Management Act 2006 with respect to services and operations (s 156). The operation of rates and their administration imports machinery in the Taxation Administration Act 2003 and Land Tax Assessment Act 2002 (s 135).

Evidence and procedure. The Act’s evidentiary provisions are stated to be in addition to the Evidence Act 1906 (s 124). The Act also gives the Director General power to certify copies of documents and analyst reports as proof (s 118, s 119), and provides presumptions about place, intent, and authorship for prosecution notices (ss 115-117, 120-121).

Administrative cooperation and information sharing. The Act authorises arrangements with corresponding authorities in the Commonwealth, other States or Territories (s 183). It also creates permissive information sharing across a defined set of agencies and departments notwithstanding secrecy or confidentiality laws, subject to guidelines (s 184). Disclosure made in good faith is protected from civil or criminal liability (s 184(6)).

Land titles and charges. Registration of memorials and notices affecting land interacts with the Transfer of Land Act 1893 and the Registrar of Titles functions (ss 95-101). The Act makes land documents registered under Part 4 Division 7 exempt from stamp duty (s 102) and binds successive owners (s 52(6)).

Quarantine, fisheries and conservation instruments. Management plans touching on fish or aquatic environments require the Fisheries Minister’s approval (s 45(5)(a)), and management plans dealing with native animals (other than fish) require the Minister responsible for the Biodiversity Conservation Act 2016 to approve them (s 45(5)(b)). Inspectors can include fisheries officers and wildlife officers in particular contexts (s 6 definitions).

Regulations and codes from other sources. Regulations and management plans may adopt codes, subsidiary legislation and standards from within or outside Australia by reference (s 190). That means operational standards used under this Act can be aligned with other jurisdictions’ instruments, subject to any text the regulations prescribe.

Criminal liability and corporate law. The Act imports the Criminal Code s 39 criminal liability of officers of bodies corporate for specified offences (s 110). This creates an interlink with corporate criminal liability principles beyond the Act.

Net effect. The Act does not operate in isolation; it both defers to and leverages other statutory regimes for taxation and land administration, chemical regulation, animal and plant welfare, public health and environmental protection. It provides mechanisms to cooperate across jurisdictions and to adopt external standards, while preserving precedence for certain existing Acts in cases of inconsistency (s 4(3)). Where the Act enables information disclosure, it does so notwithstanding other secrecy laws (s 184(5)), creating a statutory bridge for collaborative enforcement.

The compilation table and amendment notes in the source list multiple statutory changes and commencement dates. Extracting the principal legislative amendments provided in the compilation table and the in‑text amendment notes:

• Original Act and commencement: Biosecurity and Agriculture Management Act 2007, assented 12 October 2007. Various parts commenced on specified dates (s 2 and compilation table).
• 2010-2011 amendments and commencements: Provisions including s 22, Parts 4 and 5 and substantial parts of the Act commenced 22 May 2010 (Gazette references) and further provisions in 2011 (for example Part 6 Div 1 Subdiv 3 and Part 7 Div 5 commenced 12 February 2011).
• Medicines and Poisons Act 2014 amendment: s 40 amended by No. 13 of 2014 s 182(3); the compilation table records the Medicines and Poisons Act 2014 amendment entered the Act and commenced 30 January 2017 (compilation notes).
• Public Health and related consequential amendments in 2016: amendments referenced in the source (No. 19 of 2016) and related commencement dates in 2017 (some provisions).
• Biodiversity Conservation Act 2016: s 24 of 2016 s 311(2) affects references in s 4 and commenced 1 January 2019 as per compilation table.
• Local Government and Genetically Modified Crops repeal: local government amendments (No. 26 of 2016) and repeal of genetically modified crops free areas provisions (No. 34 of 2016) are recorded with their respective commencements.
• Taxation Administration Amendment Act 2019: Pt 3 (No. 11 of 2019) commenced 13 June 2019 and amended the Act’s tax and rates machinery (see s 139 amended by No. 11 of 2019 s 22).
• Veterinary Practice Act 2021 amendments: changes to definitions and references to veterinarians and pharmacy practice (No. 19 of 2021) commenced 18 June 2022 as referenced.

In‑text amendment notes show targeted, sectoral amendments such as adding the Public Health Act 2016, Medicines and Poisons Act 2014, and the Biodiversity Conservation Act 2016 into the list of legislation to be read alongside this Act (s 4(2)). The compilation table records that different provisions commenced on different dates and that certain provisions are yet to commence (see uncommenced provisions table entries for some consequential provisions and later Acts listed, where commencement is "to be proclaimed").

The Schedule 1 list of matters for which regulations may be made has been amended (noted: Schedule 1 amended No. 19 of 2021 s 227(7)) indicating periodic updating of the regulatory scope.

The cumulative effect shown in the compilation table is that the Act has been amended by sectoral and consequential statutes over time,public health, medicines and poisons, biodiversity, taxation and corporate liability,reflecting integration with other regulatory regimes. The source provides the dates and specific amending instruments rather than details of policy change rationale; those are summarised above only to the extent recorded in the compilation and in‑text amendment annotations.

The supplied statutory text contains no judicial decisions, cases or reported litigation history. It sets out administrative review routes and courts in which the Director General may seek relief, but does not cite or record any court decisions. Relevant procedural and review provisions in the Act are as follows and shape the institutional avenues where litigation could arise:

• The State Administrative Tribunal (SAT) is the prescribed avenue for review of many administrative decisions (for example review of pest exclusion notices, ss 28; pest control and pest keeping notices, ss 37; seizure, ss 74; forfeiture ss 75; treatment or destruction notices, ss 80; directions to remove from the State, ss 83; recall notices, ss 86). The Act repeatedly notes regulations may prescribe emergency circumstances where SAT review does not apply.
• The Director General may apply for injunctions in the Supreme Court or the District Court to prevent or compel actions to ensure compliance (s 109). The Act specifies the courts and the remedies available including interim injunctions (s 109(1)-(6)).
• Criminal prosecutions for offences under the Act must be commenced by the Director General or by a person authorised by the Director General (s 104). Time limits for prosecution are provided (s 105).
• The Act provides evidentiary presumptions and procedural rules that will shape litigation,rules about certified copies, analyst reports being proof in the absence of contrary evidence (ss 118-121), admissibility of compelled statements (s 93), and admission of analyses and sampling (s 119).

Because the source is the Act as compiled, and does not include annotated cases, there is no litigation dataset embedded. Practitioners should therefore look outside the statutory text to courts and SAT databases for case law interpreting key provisions (for example the scope of inspection powers, the meaning of "reasonable grounds", the reach of remedial action and charges on land, and the interaction with other statutes such as those listed in s 4(2)). The Act, however, identifies the bodies and instruments (SAT, Supreme and District Courts, Director General prosecutions) that are the proper forum for disputes and enforcement, and it contains multiple references to SAT review rights (subject to regulation) and court injunction powers (s 109) that would govern judicial and tribunal engagement in practice.

The Act’s structure creates several operational and legal risks or friction points that parties must manage; the following are concrete mechanisms and trade‑offs embedded in the statutory text.

Broad executive discretion over organism status. The Minister may declare organisms to be permitted or prohibited (ss 11-12) and may declare declared pests for areas of the State (s 22). These declarations are administrative instruments not subsidiary legislation in the strict sense but are subject to publication requirements (s 157). The Minister must consult relevant Ministers and, where necessary, the Biosecurity Council (s 13), but the statutory test for prohibition is "reasonable grounds" that an organism has or may have an adverse effect (s 12). This confers latitude over biosecurity classification that has direct compliance and criminal consequences for third parties.

Emergency carve‑outs for review. While the Act provides SAT review rights for many administrative decisions (see ss 28, 34, 37, 74, 75, 78, 80, 83, 86), the regulations are repeatedly authorised to prescribe circumstances,matters of emergency or urgent need,when these review rights do not apply. That creates legal risk in urgent biosecurity operations where expedited action may be insulated from tribunal review by regulation; the Act contemplates this explicitly (see repeated provisos).

Extensive inspector powers, including to enter non‑dwellings without warrant and dwellings with consent. Inspectors can stop, board and enter conveyances and places that are not dwellings at any time (s 65(1)(a)-(b)); entry to dwellings requires consent except where executed under an entry warrant (s 65(1)(c)-(d)). Inspectors may also exercise coercive powers over records and computers (s 66), and can seize and detain goods pending analysis or treatment (s 73). Organisations must therefore maintain procedures and rights management for inspector interactions and for handling compelled disclosure and seizure.

Seizure and destruction subject to limited but important review windows. Seizure may be followed by destruction or forfeiture (s 73(2)(d)), but actions under s 73(2)(d) must not be taken before expiry of the period for SAT review under s 74 or, where an application has been made, before determination of that application (s 73(4)). However, again, regulations may prescribe emergency circumstances where SAT review does not apply (s 74(4)). That timing element is critical to evidentiary preservation and challenge.

Charges on land and priority. The Director General may register a memorial for costs of remedial action (s 95(2)) and the memorial creates a first charge on the land upon registration (s 96(1)). This is a direct enforcement mechanism that can affect property transactions (s 97). Certificates of charge amount must be issued on request and set bounds on Director General representations (s 99). Mortgagees are to be notified when a memorial is registered (s 103). The charge is recoverable and the Director General has powers akin to mortgagees for sale if recovery fails (s 98), but the Director General must be satisfied that other reasonable means have been exhausted (s 98(4)).

Wide scope for delegated standards and imported codes. The Act allows regulations and management plans to adopt codes or other subsidiary legislation by reference (s 190). This increases regulatory agility, but it can create compliance complexity because obligations may be located in external documents adopted dynamically as they change unless the regulations lock a particular text.

Officer and vicarious corporate liability. The Act applies Criminal Code s 39 to a long list of offences (s 110) and provides express liability for principals and employers for acts of agents and employees (ss 111-112). The defences for principals and employers require proving lack of consent and reasonable measures taken to prevent the offence (ss 111(5), 112(5)). Corporate compliance programmes must therefore be demonstrable to avail those defences.

Regulatory gaps and evidence presumptions. The Act includes many evidentiary presumptions and allows approved analyst reports to be taken as proof absent contrary evidence (s 119). For regulated parties this shifts the evidentiary burden in enforcement proceedings; practitioners must be ready to test chain of custody, sample representativeness (s 119(4)), and procedural compliance with sampling regulations.

Financial burdens: rates and industry funding. The Minister can determine rates for prescribed areas to fund the Declared Pest Account (ss 130-133). While s 132 sets upper bounds on ad valorem rates (2% for most land, 10% for pastoral leases by reference), landowners in prescribed areas may face new recurring obligations and consultation is required (s 131). The Act also permits industry funding schemes by regulation including contribution, collection and refund mechanisms (ss 141-146). These schemes can allocate costs across producers and may include disqualification for compensation in prescribed circumstances (s 145(6)).

Information sharing and publication risks. The Act permits broad information sharing across specified agencies notwithstanding secrecy laws (s 184(5)) and allows the Director General to publish analysis results and other prescribed matters including names and addresses (s 185). Those powers trade privacy and reputation risks for public interest transparency.

Void and voidable commercial clauses. Agreements purporting to exclude application of the Act in relation to treatment with chemical products are void (s 58(1)), and contractual statements about whether a product has been treated may be voidable by a purchaser unless Act requirements are met (s 58(3)). Commercial parties must therefore be careful in drafting and transactional due diligence.

In sum, the Act concentrates administrative discretion in the Minister and Director General, equips inspectors with expansive operational powers, enables cost recovery measures that attach to land, allows for rapid statutory adoption of external standards, and creates vicarious liability exposure for corporate officers, principals and employers. Emergency carve‑outs for review, dynamic adoption of codes, and evidentiary presumptions are particular operational “gotchas” flagged by the statutory text.

Compliance under the Act requires a combination of regulatory monitoring, operational controls, record‑keeping and proactive engagement with the department. The Act points to concrete steps that regulated parties should adopt.

1. Monitor declarations, management plans and the department website. The Director General must maintain lists of permitted, prohibited and declared pest organisms and an electronic site with particulars of those lists and how to apply for import permits (ss 158-160). Regularly check the department’s electronic site and the Gazette for declarations, management plans (s 45) and codes of practice (s 191). Management plans and declarations may create area‑specific obligations and offences (ss 22, 45(3)-(4), 47).

2. Import controls and permits. If importing organisms or prescribed potential carriers, apply for import permits in accordance with the regulations (s 16). Provide notices of entry times and places where the regulations require and present goods to inspectors when required (s 21). If operating a commercial passenger or other carrier, ensure prescribed information is provided to passengers and a secure deposit facility is available and operated as required (s 19).

3. Record keeping and traceability. The regulations may impose qualifications, authorisations and record‑keeping obligations for chemical products and animal feed, including the keeping and production of records, giving of notices and making of declarations or returns (s 56; Schedule 1 items 26-28, 50). Maintain auditable records of acquisition, supply, storage, handling, use and transport of chemical products, animal feed and agricultural products.

4. Prepare for inspections. Inspectors may require access to records and to operate computers (s 66). Maintain contemporaneous records that can be produced, copies that can be given to inspectors, and documented identity and chain of custody for samples and consignments. Train staff on how to respond to inspector directions, how to identify inspectors and how to ask for written confirmation of oral directions (s 89(2), s 164).

5. Comply with notices and directions. If issued a pest exclusion, pest control or pest keeping notice, act promptly to comply, seek internal review by the Director General under s 36 where appropriate, and consider SAT review if aggrieved (ss 31-37). Note the timeframes and that the regulations may prescribe emergency circumstances in which SAT review rights are limited (e.g. ss 28(2), 37(2)).

6. Chemical use and residue management. If using agricultural or veterinary chemicals, ensure any required qualifications or authorisations are held, relevant records of use and disposal are kept, and labelling and packaging obligations are followed (s 56; Schedule 1 items 22, 30, 34). Where land may be contaminated, respond to residue management notices, seek the written approval of inspectors where required, and be aware that registered notifications can bind successive owners (s 52, s 55, s 101(4)).

7. Preventative biosecurity controls. Adopt codes of practice where available (s 191) and align with any relevant quality assurance scheme approved or recognised under the Act (s 6 definition; Schedule 1 item 32). For businesses in prescribed sectors, be prepared for industry funding schemes and possible payment of contributions if regulations establish them (ss 141-146).

8. Contracts and commercial arrangements. Avoid contractual clauses that purport to exclude operation of the Act in relation to chemical treatment because such clauses are void (s 58(1)). Where agricultural products are the subject of contractual warranties about chemical treatment, ensure compliance with statutory requirements and any system of declarations or returns in operation under the Act (s 58(3)).

9. Manage corporate and officer liability risk. Because the Act applies criminal liability to officers of bodies corporate for listed offences (s 110) and allows principals and employers to be charged for acts of agents or employees (ss 111-112), implement demonstrable compliance systems, training and supervision. Document policies and steps taken to prevent prohibited conduct; these are the defences the Act requires for principals and employers (ss 111(5), 112(5)).

10. Prepare for remedial action and cost recovery. Be aware that the Director General can take remedial action and recover costs, and may register a charge on land (ss 94-95). Where remedial work may be needed, keep records of steps taken and costs borne; if charged amounts are disputed use the certificate and recovery mechanisms provided (ss 99, 98).

11. Engage in consultation and dispute mechanisms. The Minister must consult on regulations and management plans as far as is reasonably practicable (ss 46, 192). Where disputes arise, use internal review by the Director General (s 36) before seeking SAT review (s 37), bearing in mind the possibility of regulatory emergency carve‑outs.

12. Data and privacy controls. Implement policies for information sharing and requests from authorised officers (s 184). Understand that disclosures made in good faith are protected from civil or criminal liability (s 184(6)), but ensure disclosures are made in accordance with the Director General’s guidelines (s 184(7)).

13. Specialist compliance: chemical advisers and veterinarians. If advising on chemical products or preparing veterinary chemicals under the narrow exclusions, ensure the specific conditions in the definitions and s 56 are satisfied and that the person providing the preparation is properly authorised (s 6, s 56).

14. Insurance and legal readiness. Given the potential for large fines and charges (including fines up to $100,000 and imprisonment for high impact organism breaches), review insurance coverage, legal retention and incident response plans to manage enforcement risk and public‑facing communication in recall or contamination incidents (s 84, s 185).

In practice, compliance means aligning operational procedures, contracts and record keeping to the substantive obligations in the Act and the detail contained in regulations, management plans and codes of practice. The department’s electronic site and the Gazette are the primary authoritative sources for up‑to‑date declarations, regulations, management plans and codes (ss 157, 159-161).
