Highways (Liability for Straying Animals) Act 1983

The Act is compact and focuses on a small number of legal concepts that determine liability for damage caused by animals straying on to highways. Each concept is expressed in statutory text and should be read together when analysing claims.

Damage: The Act defines "damage" expansively. Section 2 provides that "damage includes the death of a person; and injury to a person, including disease and impairment of mental or physical condition suffered by the person." That definition places death and personal injury within the types of lawful recoverable damage contemplated by the Act. The Act does not define property damage explicitly in the definition clause; however, s 4(1) refers to "damage" in negligence causes of action, which is broad by s 2.

Abolition of certain common law rules: Section 3(1) operates as a legislative removal of parts of the common law of negligence which "exclude or restrict the duty which a person might owe to others to take such care as is reasonable to see that damage is not caused by animals straying on to a highway." The text declares that those rules "do not form part, and shall be deemed never to have formed part, of the law of Western Australia." The statutory text therefore operates retroactively in the sense of removing those common law restraints for the law of Western Australia going forward. The subsection contains two temporal limits: it does not operate in relation to (a) actions in respect of which a court has given judgment before the Act’s commencement, and (b) appeals relating to matters in issue in such actions (s 3(2)(a)-(b)). Practically, this places the legislative change prospectively on suits not concluded before commencement.

Channeling of causes of action: Section 3(3) provides that a court shall determine liability "solely according to the law of Western Australia relating to liability in tort for negligence; or intentional acts or omissions." That channels judicial inquiry into two tort categories: negligence and intentional wrongdoing. The statutory language removes reference to any other non-WA law sources, and requires solely WA law on tort negligence or intentional acts or omissions to be applied in determining liability for damage from animals straying onto highways.

Factors for assessing negligence: Section 3(4) lists matters a court "may consider" in determining negligence in the context of animals straying on to highways. The enumerated factors are:

• the general nature of the locality where that part of the highway is situated (the locality) (s 3(4)(a));

• the nature and amount of traffic using that highway (s 3(4)(b));

• the extent to which highway users would expect to encounter animals and could be expected to guard against associated risks (s 3(4)(c));

• the common practice in the locality about fencing and other preventative measures and about taking measures to warn users of likely animal presence (s 3(4)(d)(i)-(ii));

• the cost of fencing or the taking of measures referred to in paragraph (d) (s 3(4)(e)).

These factors embed a locality-sensitive, cost-benefit style assessment into the negligence inquiry. Courts retain discretion as to weight and relevance, but the statute highlights particular considerations that frame reasonableness in the specific context of animals and highways.

Damages cap and administrative mechanism: Section 4 introduces a statutory ceiling on damages recoverable in negligence causes of action arising from animals straying on to highways. Subsection (1) mandates that damages for any one cause of action "must not exceed the maximum damages amount prescribed by the regulations for the financial year in which the damages are assessed." Subsection (2) allows regulations to specify a method for calculating the maximum damages amount for a financial year. Subsection (3) requires the Minister to publish a notice in the Gazette on or before 1 July each year specifying the maximum damages amount for the forthcoming financial year. Subsection (4) clarifies that the Gazette notice is for public information only and that a failure to publish, or a delay or error, does not affect the maximum amount. Subsection (5) is transitional for the 2016 amendment commencement period and modifies the meaning of "financial year" and the timing of the Minister’s notice for that initial application.

Regulatory power and executive role: Section 5 empowers the Governor to make regulations "prescribing matters required or permitted to be prescribed by this Act" and other necessary or convenient matters for giving effect to the Act (s 5). That provides the executive branch with a route for operationalising the damages cap and any ancillary details that the Act contemplates, such as methods for calculating the annual maximum.

Temporal and amendment record: The Compilation table records that the Act commenced on 17 November 1983 and that an amendment, the Highways (Liability for Straying Animals) Amendment Act 2016 (No 30 of 2016), amended section 3 and inserted sections 4 and 5; those amendments received assent on 3 October 2016 and various commencement provisions are recorded (Compilation table). The Act’s text also indicates that section 3 previously contained a subsection (5) that has been deleted (note in s 3).

Primary affected parties are parties who own or control animals, users of highways, and courts and the executive that administer the statutory cap and regulations.

Animal owners and controllers: The Act targets liability arising from animals straying on to highways. Persons who keep, own, manage, or have control of animals that could stray on to highways are the primary potential defendants in litigation under the Act. While the statute does not use labels such as "owner" or "keeper," its language in s 3(1) and the negligence framework set out in s 3(3) and (4) indicates that persons who might owe a duty to take reasonable care to prevent animals straying fall within the scope of the Act. The statute does not require ownership to be established in a particular way; rather, courts will determine liability under WA tort law for negligence or intentional acts or omissions (s 3(3)).

Highway users and potential plaintiffs: Drivers, passengers, cyclists, pedestrians and other users of highways who suffer death, injury, or other recoverable damage when animals stray on to highways are affected as potential claimants. The Act’s definition of damage includes death and injury (s 2). The statute constrains recoverable damages by requiring adherence to the maximum amount prescribed in regulations for the relevant financial year (s 4(1)).

Landholders and occupiers adjacent to highways: Persons who undertake measures such as fencing or warning signs, or who choose not to, will be affected by how courts weigh common local practice and the cost of such measures in determining reasonableness (s 3(4)(d)-(e)). Even if not the registered owner of animals, occupiers who have actual control or responsibility for fencing or other preventive measures may be exposed to claims assessed under the negligence factors (s 3(4)).

Insurers and risk managers: Although the Act contains no insurance mandate, insurers that underwrite liability for animals, farming operations, transport operators, or public liability will be directly interested and affected by the statutory change. The damages cap (s 4) alters the quantum exposure per cause of action and shifts the actuarial environment insurers must model. The Act does not prescribe how insureds should be indemnified, nor does it alter contractual allocation of risk, but the statutory cap and the factors courts may consider in negligence (s 3(4)) will be inputs to underwriting decisions.

Courts and legal practitioners: Courts are central decision-makers under the Act. Section 3(3) directs courts to determine liability "solely according to the law of Western Australia relating to liability in tort for negligence; or intentional acts or omissions." The courts will apply s 3(4)’s list of considerations when assessing reasonableness. Legal practitioners acting for plaintiffs or defendants will structure pleadings, evidence and expert testimony around the locality, traffic characteristics, expected presence of animals, local practices on fencing and warnings, and costs of preventive measures (s 3(4)(a)-(e)).

Executive branch and regulators: The Governor and Minister are assigned administrative roles. The Governor may make regulations for matters required or convenient to give effect to the Act (s 5). The Minister must publish the maximum damages amount for each financial year in the Gazette on or before 1 July (s 4(3)). Regulations may prescribe the maximum damages amount and the method for calculating it (s 4(1)-(2)). The Minister’s annual publication is labelled as "for public information only" and its non-publication does not affect the statutory maximum (s 4(4)).

Road authorities and local government: Road managers and local governments responsible for highways may be indirectly affected. The negligence inquiry includes consideration of the nature and amount of traffic using the highway (s 3(4)(b)) and the extent to which users would expect to encounter animals (s 3(4)(c)). Evidence about signage, warnings and road management practices in the locality may be relevant in litigation. The Act does not alter statutory duties road authorities may hold under other legislation; it confines attention to tort liability for animals straying.

General public and taxpayers: The statute may have indirect fiscal implications via potential claims and public sector liabilities where public authorities or employees are implicated in negligence or intentional acts leading to animals straying on to highways. The Act itself does not allocate public funding or insurance, but any public bodies that are defendants will be subject to the Act's liability framework and the damages cap (s 4).

Excluded or protected groups: Section 3(2) protects finalised litigation by excluding any action in respect of which a court had given judgment before the Act commenced and appeals relating to those matters. Therefore litigants with judgments entered prior to commencement are not affected by the abolition of common law rules. No other exemptions or special classes are identified in the Act.

The Act does not create a statutory offence or an enumerated duty with a specific compliance regime. Instead, it restructures the legal duty analysis in civil tort and specifies rights to damages within a capped framework.

Duty to take reasonable care: The Act clarifies that the common law rules that previously "exclude or restrict the duty" to take reasonable care to prevent animals straying on to highways are not part of WA law (s 3(1)). That legislative removal implies that, where relevant, a person may owe a duty to others to take such care as is reasonable to ensure animals do not stray on to highways. The content and scope of that duty are to be assessed under WA tort negligence law and informed by the factors set out in s 3(4). The statute therefore reframes the duty enquiry rather than creating a freestanding, prescriptive statutory standard.

Right to recover damages for death and personal injury: The Act’s definition of damage explicitly includes death and injury, including disease and impairment of mental or physical condition (s 2). Plaintiffs may therefore pursue civil causes of action in negligence or for intentional acts or omissions (s 3(3)) for those kinds of loss when animals stray on to highways. The recovery is subject to the maximum damages amount set by regulation for the financial year in which damages are assessed (s 4(1)).

Limits on recoverable amounts: Section 4(1) imposes a statutory ceiling on damages "in respect of any one cause of action in tort for negligence arising out of damage caused by animals straying on to a highway." The ceiling is not fixed in the Act; it is prescribed by regulations and announced each financial year by the Minister in the Gazette (s 4(1)-(3)). The Act allows regulations to prescribe the method of calculating the annual maximum damages amount (s 4(2)). Therefore claimants’ rights to recover are subject to a legislatively enabled and administratively set monetary restriction.

Scope of judicial determination: Section 3(3) requires that courts determine liability "solely according to the law of Western Australia relating to liability in tort for negligence; or intentional acts or omissions." That instruction circumscribes the legal sources that courts must apply when adjudicating liability for animals straying on highways. It affirms courts’ role in applying local tort law principles to questions of duty, breach, causation and remoteness of damage.

Factors relevant to the reasonable care inquiry: Section 3(4) gives courts statutory guidance by listing matters that they may consider relevant in negligence cases concerning animals on highways. These factors do not supplant judicial fact-finding but give statutory indicators of what constitutes reasonable care in context. Evidence about locality, traffic, user expectations, local fencing and warning practices, and cost of preventive measures is therefore central to the duty and breach assessment.

No statutory affirmative obligations to fence or warn: Although courts may consider whether fencing or other measures were taken in the locality and their cost (s 3(4)(d)-(e)), the Act does not impose express statutory obligations on particular persons or categories of persons to fence, control animals, or erect warnings. The statute leaves the content of the duty to the negligence analysis.

Executive duty to publish cap: The Minister has a statutory administrative duty to publish in the Gazette the maximum damages amount for the financial year beginning each 1 July (s 4(3)). The Act treats this publication as informational only and says a failure to publish, or a delay or error in publication, does not affect the maximum amount (s 4(4)). The Act therefore creates an administrative duty of announcement without conditioning the legal validity of the cap on publication.

Regulatory authority and rights to make regulations: The Governor, by s 5, has power to make regulations "prescribing matters required or permitted to be prescribed by this Act" and matters necessary or convenient to give effect to the Act. This vests the executive with authority to implement quantitative elements (the maximum damages amount and calculation method) and other procedural or administrative matters relevant to the Act’s operation.

Preservation of prior judgments: Section 3(2) preserves the finality of judicial decisions where judgment had already been given before the Act's commencement. Parties with existing judgments before commencement are protected from the retrospective effect of the statutory abolition of certain common law rules.

No criminal penalties or enforcement procedures: The Act contains no provisions creating criminal offences, specifying enforcement agencies, or setting procedural mechanisms for non-civil enforcement. The primary operative rights and duties are civil and litigative.

The Act establishes a civil liability framework rather than a penal or administrative enforcement regime. It does not create criminal offences or impose statutory fines, nor does it prescribe administrative enforcement measures.

Civil enforcement through tort litigation: The mechanism by which the Act’s rules are applied is civil litigation in the courts. Section 3(3) requires courts to determine liability "solely according to the law of Western Australia relating to liability in tort for negligence; or intentional acts or omissions." Enforcement therefore occurs through ordinary civil processes available in WA courts: plaintiffs sue for damages; courts determine duty, breach, causation and remedy according to WA tort law and the Act’s guidance. The Act does not specify procedural rules, limitation periods, service, or interlocutory procedures; ordinary civil procedure rules and applicable limitation legislation remain the operative procedural framework.

Monetary cap as a statutory limit on awards: Section 4(1) imposes a statutory upper limit on damages recoverable in a single cause of action in negligence arising from animals straying on to a highway. The cap is to be prescribed by regulation for the financial year in which damages are assessed. That statutory cap functions as a statutory constraint on remedies, effectively limiting amounts a successful plaintiff may recover in a civil suit. The Act does not provide for administrative adjustments or judicial discretion to exceed the cap; the language is mandatory: damages "must not exceed" the prescribed maximum (s 4(1)).

Administrative roles in setting the cap: Enforcement of the cap requires the executive to set the maximum amount by regulation and for the Minister to publish a notice in the Gazette specifying the amount for each financial year (s 4(2)-(3)). The Governor’s regulation power (s 5) and the Minister’s publication obligation (s 4(3)) are administrative steps that operationalise the cap. The Act clarifies that failure to publish, or delays or errors in publication, do not affect the maximum amount (s 4(4)). This reduces the risk that technical publication failures would invalidate the cap, but it centres authority for the cap in the regulatory instrument and the Minister’s announcement.

No specified penalties for non-publication: The Act imposes no penalty on the Minister, the Governor, or any official for failure to make the Gazette publication on time or accurately. Subsection 4(4) absolves such failure from affecting the legal maximum, thereby insulating the cap from publication lapses but creating no enforcement remedy for the public to compel prompt publication.

No special enforcement powers for regulators: Section 5 grants regulation-making power to the Governor but does not create separate enforcement agencies or investigative powers. Any regulation that prescribes matters "necessary or convenient" to implementation must be exercised under existing executive mechanisms.

Interaction with other civil remedies and limitation regimes: The Act does not expressly displace other civil remedies. Section 3(3) confines the determination of liability to WA tort law for negligence or intentional acts or omissions. Nothing in the Act provides for alternative dispute resolution, statutory compensation schemes, or non-litigation mechanisms. Ordinary civil procedure and applicable statutes elsewhere (for example limitation acts, if any) remain the enforcement context. The Act’s preservation of prior judgments (s 3(2)) also protects concluded litigation from being reopened under the new statutory regime.

Practical enforcement consequence: The statutory cap creates a compliance-incentive for defendants, insurers, and claimant lawyers to assess cases with an awareness of the annual maximum. Plaintiffs’ recovery expectations are bounded by the cap, which may influence settlement negotiations and the economics of litigation. The Act does not specify how to prorate or split a cap across multiple claimants where a single cause of action gives rise to multiple claimants; such questions will require litigation or regulation to resolve under the statutory framework.

The Act is limited in scope and directs courts to apply Western Australian tort law; it therefore sits alongside other legal instruments rather than replacing them. The statutory text itself provides only limited cross-reference to other law.

Supersession of certain common law rules: Section 3(1) explicitly declares that so much of the common law rules of negligence as excluded or restricted the duty to take reasonable care in relation to animals straying on to highways "does not form part, and shall be deemed never to have formed part, of the law of Western Australia." That statutory statement operates within the WA legal system to remove certain historical judicially-created restrictions from the body of WA common law. The removal is prospective except for the preservation of judgments given before commencement (s 3(2)). The Act does not identify the specific common law precedents or doctrines being removed; it provides the legislature’s statement of law to be applied within WA courts.

Primacy of WA tort law for adjudication: Section 3(3) requires courts to determine liability "solely according to the law of Western Australia relating to liability in tort for negligence; or intentional acts or omissions." This instruction restricts courts to WA tort principles for such matters. It does not expressly address the interplay with federal legislation, if any, or with other State Acts that affect highways, animals, or public safety. Where other statutes create duties, immunities, or compensation schemes, courts will need to reconcile those instruments with the Act’s specific direction that liability for animals straying on to highways be determined under WA tort law for negligence or intentional acts or omissions. The Act does not purport to modify or override other statutory duties or immunities except as regards the particular aspect of common law restrictions to duty referred to in s 3(1).

Relation to property, fencing and animal control laws: Section 3(4) explicitly makes the common practice in the locality about fencing and other measures relevant to the negligence inquiry, and makes the cost of fencing a matter a court may consider (s 3(4)(d)-(e)). The Act leaves intact any separate legislative regimes that create obligations to fence, control animals, or register stock. If other legislation requires particular animal-control measures or places duties on landholders or occupiers, those statutory duties will coexist with the negligence inquiry under this Act. The Act does not specify that compliance with any such statute is conclusive proof of reasonable care; rather, compliance or non-compliance will be evidence bearing on the negligence assessment in light of s 3(4).

Interaction with compensation statutes or public authority immunity: The Act does not address compensation schemes established by other statutes nor does it expressly modify liabilities of public authorities. If a public authority faces civil claims for animals straying on to highways, the Act’s instruction to courts to determine liability under WA tort law will apply to the extent that other statutes do not provide contradictory provisions. The Act does not create or remove sovereign immunity or indemnity provisions that might exist elsewhere in statute or contract.

Regulatory interplay for damages cap: Section 4 delegates the maximum damages amount to regulations and administrative publication. That means the cap’s quantum and calculation method will be set by regulations made under the Governor’s power in s 5. The Act therefore interacts procedurally with the Subordinate Legislation Act or similar statutory regimes governing how regulations are made, tabled, reviewed or challenged in Parliament. The Act itself does not set the cap; it leaves that to regulation, thereby requiring users to consult regulations and the Minister’s Gazette notices each financial year to know the applicable cap (s 4(2)-(3)).

Transitional judicial finality: Section 3(2) preserves judgments delivered before the Act’s commencement and appeals relating to those matters. This creates a temporal interface with prior litigation and prevents the Act from reopening concluded cases. The Act therefore coexists with earlier judicial decisions in that concluded matters remain governed by the law as it stood when judged.

Limits of statutory displacement: The Act abolishes only "so much of the rules of the common law relating to liability in tort for negligence as excludes or restricts the duty" in the specific context of animals straying on to highways (s 3(1)). It does not purport to displace other common law principles unrelated to that specific duty. Courts will need to determine which common law rules fall within the statutory abolition and which remain. The Act itself provides a framework for that inquiry but does not give an exhaustive list.

The Act’s text and compilation table record two distinct historical points: enactment in 1983 and amendment in 2016 with specified insertions and commencement dates.

Enactment: The Highways (Liability for Straying Animals) Act 1983 was enacted as Act No. 17 of 1983, received assent on 17 November 1983 and commenced on the same date, 17 November 1983 (Compilation table).

2016 amendment: The Highways (Liability for Straying Animals) Amendment Act 2016 (No. 30 of 2016) amended the original Act. The compilation table records that the Amendment Act received assent on 3 October 2016. Commencement is divided: sections 1 and 2 commenced on 2 December 2016 (see s 2(a) of the Amendment Act); the remainder of the Amendment Act commenced on 3 December 2016 (see s 2(b) and Gazette 2 Dec 2016 p. 5383) (Compilation table). The Act’s internal notes state that section 3 was amended by No. 30 of 2016 s 4, and that sections 4 and 5 were inserted by No. 30 of 2016 s 5 (see notes beneath relevant sections). Section 3 also contains an internal note that subsection (5) has been deleted; the compilation or amendment notation (Section 3 amended: No. 30 of 2016 s. 4) corroborates the 2016 change.

Nature of 2016 changes: The 2016 amendments appear to have two material effects visible from the text: (a) amendment to section 3 (the core provision on liability and the factors for negligence); and (b) the addition of a new statutory ceiling mechanism and administrative procedure for setting maximum damages per cause of action (s 4 as inserted) together with a regulation-making head of power (s 5 as inserted). The Compilation table and the notes appended to sections 3, 4 and 5 identify those amendments explicitly.

Transitional provision: Section 4(5) is a transitional provision inserted with the 2016 amendment. It provides temporary directions for applying section 4 to the financial year that includes the commencement day of the Amendment Act’s section 5, redefining references to "financial year" and the Minister’s publication date for that initial period (s 4(5)). This indicates legislative attention to the first-year timing of the damages cap mechanism.

Deleted subsection: Section 3 contains an editorial note that subsection (5) has been deleted. The Act does not set out the text of the deleted subsection in the present compilation. The annotation "Section 3 amended: No. 30 of 2016 s. 4" confirms that the 2016 Amendment Act altered section 3, which may have included deleting previously existing subsection (5).

No other recorded amendments: The Compilation table lists only the original Act (1983) and the 2016 Amendment Act. There are no other amendments or subsequent reprints recorded in the provided compilation beyond the reprint as at 11 Oct 2002 and the 2016 Amendment Act entries.

Interpretation of amendment scope: The 2016 amendments materially shifted the statute from a framework that abolished certain common law defences and provided statutory guidance for negligence to one that also imposes an annually prescribed maximum for negligence damages arising from animals straying on highways and creates a head of regulation-making power. The amendments thus combined judicial reframing with an executive-administered monetary cap.

The Act as supplied does not name or summarise any cases, judgments, or reported litigation. The statutory text contains no references to judicial decisions, nor does the compilation table list any case law or legal proceedings interpreting the Act. Section 3(2) protects actions in respect of which judgment had already been given before the Act’s commencement and appeals relating to those matters; but the Act does not catalogue those cases.

What the Act itself makes relevant for litigation: The statute directs courts to determine liability solely according to WA tort law for negligence or intentional acts or omissions (s 3(3)), and it lists matters courts may consider in negligence cases (s 3(4)). Therefore litigation that arises under the Act will focus on:

• whether a duty of reasonable care existed in the circumstances, given the abolition of certain common law rules (s 3(1));

• factual inquiries about the locality, traffic, user expectations, and common local practices relating to fencing and warnings (s 3(4)(a)-(d));

• the cost of fencing or other measures and how that factors into reasonableness (s 3(4)(e));

• whether the harm arose from negligence or intentional conduct (s 3(3));

• quantum questions subject to the statutory maximum for the financial year in which damages are assessed (s 4(1)); and procedural questions as to how the cap is to be applied under regulations (s 4(2)).

Potential litigation issues that the Act implicitly creates, to be litigated under WA tort law: Because the Act abolishes certain limits on duty (s 3(1)) but provides a non-exhaustive list of factors bearing on reasonableness (s 3(4)), litigated disputes will likely address how those factors are weighed against each other in particular cases. The Act does not specify how to apportion the cap when multiple claimants or heads of damage are involved in a single cause of action; absent regulatory detail, courts will be required to interpret the cap’s application to complex fact patterns. The Act also leaves open how compliance with existing statutory schemes regarding animals, fencing or highways will be treated when determining reasonableness under WA tort law. These points are matters for litigation, though no cases are provided in the text.

No appellate history provided: The Act contains no record of appeals or higher court decisions applying or construing its provisions. Section 3(2) preserves decisions rendered before commencement but does not list them. Any litigants wishing to understand how courts interpret the statutory factors, the scope of the abolished common law rules, or the operation of the damages cap will need to consult case law sources external to the Act.

The Act is concise but contains several features that can catch practitioners and affected persons unaware if they rely on assumptions from pre-amendment common law, practice in other jurisdictions, or on ministerial publication.

Abolition of certain common law limits to duty, but not spelt out which ones: Section 3(1) abolishes "so much of the rules of the common law relating to liability in tort for negligence as excludes or restricts the duty" to take reasonable care to prevent animals straying on to highways. The Act does not catalogue which common law rules are removed. Practitioners should not assume a particular defence or restriction has been preserved. The statute’s language leaves it to courts to determine how the abolition operates in specific contexts under WA tort law (s 3(3)).

Duty remains context-dependent: The Act does not impose an absolute statutory duty to fence, warn, or otherwise prevent animals straying. Instead, courts assess what is "reasonable" by reference to statutory factors (s 3(4)). Clients should not infer a bright-line obligation from the Act. Reasonableness turns on locality, traffic, users’ expectations, local practices and costs (s 3(4)(a)-(e)).

Damages cap is statutory and annually set, not fixed: Section 4(1) ties the maximum damages amount to regulations for the financial year. The Act itself contains no monetary figure. Practitioners and parties must consult the regulations and the Minister’s Gazette notice for the applicable cap in any given financial year (s 4(2)-(3)). Assuming a static or historical figure risks error.

Publication failure does not invalidate the cap: Subsection 4(4) states the Minister’s Gazette notice is "for public information only" and that failure to publish, or a delay or error in publication, does not affect the maximum damages amount. Practitioners cannot rely on the absence of a Gazette notice to argue that the cap is inapplicable. The legal maximum is set by regulation irrespective of publication to the extent the regulation is validly made.

Transitionary period adjustments: For the financial year that includes the Amendment Act’s commencement day, s 4(5) redefines references to "financial year" and adjusts the Minister’s publication date. Failure to take this transitional provision into account for early commencement year claims can lead to miscalculation of the applicable maximum. The Act contains the transitional text which must be read for that first-year application.

No mechanism in the Act for exceeding the cap: The Act states damages "must not exceed" the prescribed maximum (s 4(1)). There is no express power for a court to exceed the cap in exceptional circumstances. Absent a regulation or other statutory provision to the contrary, claimants are bound by the statutory ceiling.

Practical evidence requirements: Section 3(4) lists factors a court "may consider." Litigants must therefore marshal locality-specific evidence: expert evidence on traffic and user expectations, surveys of local practice about fencing and warnings, comparative fencing cost estimates, and documentation showing what preventive measures were or were not taken. Failure to adduce tailored local evidence risks courts making less favourable determinations on duty or breach.

Uncertainty about allocation among multiple claimants: The Act caps damages "in respect of any one cause of action in tort for negligence arising out of damage caused by animals straying on to a highway" (s 4(1)). The Act does not specify whether the cap applies per claimant, per defendant, or per event, where multiple claimants arise from a single cause of action. This ambiguity will need judicial or regulatory clarification. Parties should not assume a particular allocation without reference to regulations or case law.

Interaction with other statutory duties and liabilities: While the Act channels liability to WA tort law (s 3(3)), it does not expressly displace other statutory obligations that may impose duties regarding animals, fencing or road safety. Practitioners should check for coexisting statutory regimes that may impose independent obligations or defences. The Act’s silence on these interactions can create unexpected overlaps or gaps.

No criminal or administrative penalties: The Act contains no criminal sanctions or administrative enforcement mechanisms. Clients seeking punitive or regulatory remedies cannot find them in this Act. Remedies remain civil damages, subject to the statutory cap (s 4).

Deleted subsection history and ambiguous legacy text: Section 3 notes that subsection (5) has been deleted. Where historical practice relied upon text no longer present, caution is needed. Practitioners must rely on the current version of the statute and the compilation table showing the 2016 amendments.

Reliance on Gazette notice timing: While the Minister must publish the maximum damages amount on or before 1 July each year (s 4(3)), the provision that publication failures do not affect the amount (s 4(4)) means litigants cannot delay proceedings or argue the cap is inapplicable because of missed publication. The administrative nature of the notice and the legal independence of the regulation mean the cap is effective irrespective of publication errors.

Compliance under this Act is principally about risk management to reduce the likelihood of civil liability and preparing to operate within the statutory damages cap and evidentiary framework. The Act does not prescribe fixed compliance steps but provides factors that define reasonableness and an annual cap that affects liability economics. The steps below translate statutory cues into practical action points grounded in the Act’s text.

Assess whether a duty of reasonable care exists in circumstances: Under s 3(1) and (3), the availability of a duty to take reasonable care is a question of WA tort law. Owners, occupiers and animal controllers should treat this as a live legal risk. A site-specific risk assessment should consider the likelihood that animals could stray on to the relevant highway and whether, in the particular locality and on the existing facts, a court might find a duty of reasonable care.

Document local conditions and common practices: Section 3(4) lists the general nature of the locality, traffic, users’ expectations, and common practice in the locality about fencing and warnings as matters a court may consider. To prepare evidence for or against liability, parties should document:

• the character of the locality (rural, semi-rural, urban fringe);

• traffic levels and types of users on the relevant highway segment;

• historical instances of animals on the road in the locality;

• local practices regarding types of fencing, boundary maintenance, stock management, and warning signage;

• community information such as local council road safety notes or farming association norms.

Collect and retain cost evidence for preventive measures: The Act instructs courts that cost of fencing or other measures is a relevant matter (s 3(4)(e)). Parties should obtain contemporaneous written estimates and invoices for fencing or other measures (labour, materials, barrier design), and keep records of decisions not to adopt particular measures with cost comparisons. This will be relevant to reasonableness assessment should litigation occur.

Implement proportionate preventive measures where reasonable: The Act frames reasonableness by reference to locality and cost (s 3(4)). Owners and occupiers should evaluate whether installing fencing, gates, use of stock-guards, microchipping, or signage would be considered reasonable in their locality. Where preventive measures are proportionate in cost and consistent with local practice, adopting them can be evidence of reasonable care. Conversely, failure to take reasonable steps that are cheap and common in the locality can be adverse evidence.

Maintain records of animal control practices and personnel training: Evidence that animals were properly supervised, contained and managed is relevant to negligence inquiry. Records of grazing rotations, muster logs, fencing inspections, contractor maintenance, and staff training in stock control will assist in demonstrating reasonable care.

Review and update insurance and indemnity arrangements: The statutory damages cap (s 4(1)) modifies exposure but does not eliminate it. Insureds should consult insurers to confirm cover terms for liability arising from animals straying on to highways, and to ensure policy limits, exclusions and deductibles are aligned to the regulatory maximums and to practical risk exposure.

Monitor regulations and the Minister’s Gazette notices annually: Because the maximum damages amount is prescribed by regulation for each financial year and the Minister is to publish the amount on or before 1 July (s 4(2)-(3)), compliance requires checking the Regulations and the Gazette notice annually. The Gazette notice is "for public information only" and non-publication does not invalidate the maximum (s 4(4)), so consultees must rely principally on the regulation and the published calculation method where provided.

Seek legal advice on multiplicity and allocation issues: The Act is silent on allocation of the cap across multiple claimants or the interplay between several causes of action arising from a single event. Parties should obtain legal advice where more than one claimant may assert loss from the same incident to address how the cap may be applied or allocated in practice.

Prepare a litigation evidence plan tailored to s 3(4): For plaintiffs seeking damages, evidence should establish the nature and extent of the damage (including death or injury as defined in s 2), causation linking the animal’s presence to the harm, and quantify loss within the regulatory maximum. Defendants should plan to adduce locality, traffic, warning measures, and cost evidence to challenge assertions of unreasonable conduct. Both sides should plan for expert evidence on fencing standards, traffic engineering, or animal behaviour where appropriate.

Consider alternative dispute resolution and settlement practice: Given the statutory cap constrains recoverable amounts (s 4(1)), parties should model settlement strategy accordingly. Early settlement discussions may be influenced by the cap, the costs of litigation relative to the maximum recoverable, and the evidentiary strengths of locality and cost defences.

Keep governance records if acting as road authority or public body: Public entities implicated in incidents should document any road signage, animal control coordination, or emergency responses, in case these are relevant to negligence inquiries under s 3(4)(b)-(d).

Check for overlapping statutory obligations: Compliance actions under this Act should be coordinated with compliance under other Acts that regulate animals, fencing, or highways. Implementing measures that meet statutory requirements under other laws will also feed into a court’s assessment of reasonableness under the Act.

Review practices after any regulatory change: Because the maximum damages amount and its calculation may be altered by regulation (s 4(2)), stakeholders should reassess their risk models and operational decisions whenever the Regulations are changed or the Minister issues a new Gazette notice.

Engage in policy and regulatory consultation where appropriate: Persons and organisations with significant exposure may wish to monitor and participate in consultation on regulations (s 5) that set the cap or prescribe calculation methods, to ensure practicalities such as allocation among claimants are addressed in subordinate legislation rather than being left to litigation.
