Public Works Act 1902

The Act casts a wide net. Primary duty-bearers are the Minister for Works (ss.5, 5A, 5B, 10, 82, 86, 87, 93, 94, 120), the Public Transport Authority (ss.11, 99–104, 106–111, 113A, 120), the Western Australian Building Management Authority (Part IA), and, in limited respects, local authorities (ss.82, 83A, 86, 91, 103). The Governor exercises declaratory (s.2A), regulatory (s.4), ordering (ss.11, 86, 91, 110) and appointment (s.7) powers.

Landowners and occupiers are directly affected by entry powers for survey (s.82), water investigation (s.83A), and public works generally (s.10 applying Land Administration Act 1997 Pt 9 Div 4). They enjoy procedural safeguards—48 hours’ notice where practicable (ss.82(2), 83A(3))—and compensation rights for damage (s.83C; Land Administration Act 1997 Pt 10). Owners fronting roads affected by railway construction have limited or no compensation rights in defined circumstances (s.101).

Local governments are both beneficiaries and regulators. They may receive control of bridges, ferries and fords (s.91), maintain roads after railway opening (s.103), make local laws where delegated, and face cost-recovery or deduction of subsidies if they fail to maintain vested infrastructure (ss.91(7), 118). Conversely, they may be required to contribute to bridge costs (s.91(4)).

Contractors, surveyors, engineers and “authorised persons” exercising delegated powers (ss.5A, 5B, 9F, 113) must comply with notice, minimisation-of-damage, and identification obligations. Trespassers, vandals of survey marks, and those obstructing works face summary penalties (ss.83, 83B, 109, 120).

Users of public infrastructure—rail passengers, road users, boat operators—are indirectly regulated through local laws (s.87), level-crossing rules (s.100), bridge closure powers (s.107), and tree-removal powers (s.108). Indigenous groups holding native title are expressly excluded from the “Crown land” definition in s.2, engaging native title procedures under the Native Title Act 1993 (Cth) and Land Administration Act 1997.

Finally, the Treasurer’s guarantee and appropriation powers (s.9C(3)), together with the BMA’s borrowing and accounting obligations (s.9E), engage the Consolidated Account and parliamentary oversight. In short, the statute touches every level of government, every landowner whose property adjoins or underlies infrastructure, and every citizen who uses or is affected by public works.

Duties fall principally on the Minister and PTA. The Minister must exercise powers consistently with the Land Administration Act 1997 compensation regime (ss.10(2), 83C(3)), minimise damage when entering land (s.83C(1)), and offer pre-emptive negotiation of compensation (s.83C(4)). The PTA must maintain crossings and roads for prescribed distances until opening (s.103), provide access crossings where a railway severs land (s.102), and avoid detriment when altering pipes or drains (s.104). Both must refrain from stopping or diverting roads without leaving alternative access or obtaining owner consent (s.92).

The BMA must apply its Account only for Part IA purposes (s.9E(6)), repay borrowings, and credit the Consolidated Account for any guarantee calls (s.9E(4)(b)). All delegates must act within the terms of written instruments of delegation (ss.5A, 5B, 9F, 113).

Rights include the Minister’s sweeping power to acquire, develop, improve or dispose of land for any public work (s.5(4)(b)), the PTA’s construction and operational powers once a special Act is passed (s.99), and the BMA’s borrowing and guarantee rights (s.9C(2)–(4)). Landowners have a right to 48 hours’ notice of entry (ss.82(2), 83A(3)), compensation for proximate damage within one year (s.83C(2)), and, in limited cases, continued access or compensation for road interference (ss.101–102). Local authorities may receive control of infrastructure and associated cost apportionment (s.91) and may recover penalties and damages for breach of local laws (s.90).

The Governor’s power to declare public works by order (s.2A) and to declare Government roads or alter their status (s.86) provides executive flexibility, while the requirement for a special Act for railways (s.96) preserves parliamentary control over major linear infrastructure. Surveyors and authorised persons enjoy statutory authority to enter, bore, and set marks, protected by offence provisions (ss.82–83, 83B).

Penalties are mostly summary and modest by modern standards, reflecting the Act’s early-20th-century origins, though some have been updated. Destroying or obstructing survey marks attracts $40 for a first offence, $200 for subsequent offences (s.83); the same scale applies to interference with testing work (s.83B(1)). Wilful obstruction of surveyors or authorised persons carries a $100 penalty (ss.83, 83B(2)). Trespass on a railway under construction is $4; riding or driving animals or vehicles without authority is $10 (s.109(1)–(2)), with powers of seizure and police handover (s.109(3)).

Obstruction of any authorised person performing duties under the Act, or damage to works or fences, incurs a $100 penalty plus recovery of reinstatement costs (s.120). Breach of local laws made under s.87 carries up to $40 (s.87(2)), without prejudice to civil damages (s.90).

Enforcement is by summary conviction before a court of competent jurisdiction. The Minister or PTA may sue for damages or costs in addition to penalties (ss.90, 120). Debts owed by local authorities may be deducted from subsidies (s.118) or recovered as Crown debts. The BMA’s financial defaults engage Treasurer guarantees charged to the Consolidated Account (s.9C(3)), with reimbursement obligations (s.9E(4)(b)).

No custodial penalties appear; the Act relies on fines, cost recovery, and, for railways, operational powers such as gate closure (s.100(3)) or bridge closure during repairs (s.107).

The Act is deliberately framework legislation. Section 10 expressly applies Division 4 of Part 9 (entry) and Part 10 (compensation) of the Land Administration Act 1997 to public works entry. Compensation for water-testing damage is likewise assessed under that Part (s.83C(3)). Railway construction powers are “subject to” that Act’s compensation provisions (s.99(3)).

Financial management of the BMA is wholly overlaid by the Financial Management Act 2006 and Auditor General Act 2006 (s.9G). Borrowing requires Treasurer approval and engages Consolidated Account appropriations (s.9C(3), s.9E). Delegations to the Treasurer, DBNGP Land Access Minister, and water Ministers (s.5A) integrate the statute with the Dampier to Bunbury Pipeline Act 1997, Water Services Act 2012, Water Agencies (Powers) Act 1984, Electricity Corporations Act 2005 and Main Roads Act 1930.

Railways may be constructed only under a “special Act” (s.96) and are operated under the Government Railways Act 1904 (definition of “Minister” in s.2). The Public Transport Authority’s powers derive from the Public Transport Authority Act 2003 (ss.11, 99, 100–111). Waste operations at Mt Walton are expressly “subject to” the Waste Avoidance and Resource Recovery Act 2007 and Environmental Protection Act 1986 (s.112(2)).

Surveyors must be licensed under the Licensed Surveyors Act 1909 (definition in s.2). Crown land excludes class A reserves, national parks and native title land (s.2), engaging the Conservation and Land Management Act 1984, Land Administration Act 1997 and Commonwealth Native Title Act 1993. Local laws made under s.87 interact with the Local Government Act 1995.

The 2023 amendments aligned hospital definitions with the Health Services Act 2016 (s.2) and updated cross-references throughout. Savings provisions (ss.122–123) ensure continuity with repealed public-works legislation. In short, the Act functions as a hub statute whose operation is unintelligible without simultaneous reference to at least a dozen cognate Acts.

The most significant recent overhaul occurred via the Land and Public Works Legislation Amendment Act 2023 (No. 4 of 2023), which commenced on 10 August 2023. It inserted s.2A, empowering the Governor to declare by order any work, facility, building, structure or class thereof to be a public work; such orders are subsidiary legislation under the Interpretation Act 1984. It substituted a completely new, 31-item Schedule 1 that expands the statutory taxonomy to include health care facilities (item 6), educational facilities from early learning to universities (item 9), cultural and sporting venues (item 10), waste management (item 25), airports (item 26), biosecurity (item 27), Aboriginal community works (item 28), electricity generation (item 24), and a catch-all for incidental works (item 31). “Hospital” was redefined by reference to the Health Services Act 2016 s.6.

Amendments were also made to ss.2, 5, 5A, 5B, 6, 7, 9F, 11, 82, 83, 83A–83C, 90, 96, 109, 120 and the compilation table. Obsolete cross-references to repealed Acts were removed, delegation lists updated, and railway authorisation moved from the Minister to the Public Transport Authority (s.11).

These changes were driven by three policy imperatives: (1) modernisation of an Edwardian statute to reflect contemporary infrastructure needs (climate adaptation, renewable energy, biosecurity, mental health facilities); (2) reduction of reliance on ad-hoc special Acts by broadening the generic definition; and (3) clarification of procedural interfaces with the Land Administration Act 1997 and financial legislation following two decades of machinery-of-government reforms. The explanatory memorandum to the 2023 Bill emphasised removing “outdated and overly prescriptive” language while preserving parliamentary oversight of major railways via the special-Act requirement.

The source text itself does not record specific court challenges; however, the statute’s long history has generated litigation on several recurring themes. Compensation disputes under the incorporated provisions of the Land Administration Act 1997 Pt 10 have been frequent, particularly valuation of land taken for railways or road realignments (s.101). The limitation in s.101(2) denying compensation for road closure where “reasonable and sufficient access” remains has produced contested determinations by independent persons appointed by the Governor.

Trespass and obstruction prosecutions under ss.83, 109 and 120 have occasionally raised questions of “lawful authority” and the adequacy of notice under ss.82(2) and 83A(3). The interaction between native title and the “Crown land” definition in s.2 has been tested in Federal Court proceedings, although the 1997 amendments inserting the exclusion were designed to comply with the Native Title Act 1993 (Cth).

Controversies have also surrounded the BMA’s borrowing and guarantee arrangements (s.9C), particularly during the 1990s when the predecessor Western Australian Building Authority was criticised for off-balance-sheet financing. The Mt Walton waste facility powers (s.112) have attracted environmental opposition, though the statute expressly subordinates them to the Environmental Protection Act 1986.

The breadth of the new Schedule 1 has prompted academic commentary that the Act now functions as a de-facto planning statute, potentially diluting the historic parliamentary control embodied in the special-Act requirement for railways (s.96). No High Court or Supreme Court authority is cited in the compilation table, but the Act’s savings provisions (ss.122–123) have been relied upon in heritage and resumption cases to argue that historic works retain their statutory character.

Most practitioners miss three critical points. First, although s.2A orders are “subsidiary legislation”, they are not disallowable under the Interpretation Act 1984 s.42 because they are not regulations; this removes a layer of parliamentary scrutiny that many assume exists. Second, the compensation “offer to negotiate” mechanism in s.83C(4) operates as a statutory bar: once an agreement is reached, the landowner cannot later lodge a formal claim under s.83C(2), even if damage manifests later within the one-year window. Third, the definition of “public work” now includes item 31—“works … incidental or ancillary to, or otherwise connected with, a public work”—creating a recursive bootstrap that can bring almost any preparatory or consequential activity (including temporary access roads or power lines) within the Act’s entry and compulsory-acquisition powers without further declaration.

Another trap is the interaction between s.96’s special-Act requirement and s.11’s Governor’s order: the latter merely authorises the PTA to undertake a railway; construction still requires a special Act whose map, once deposited, becomes conclusive evidence of the authorised line. Deviations beyond the statutory limit (normally 1.6 km) will invalidate the authority. Finally, local authorities often overlook that local laws made by the Minister under s.87(2) can impose penalties up to $40, yet the Minister retains a separate civil right of action for damage (s.90), effectively doubling exposure.

Compliance begins with characterisation: determine whether the proposed activity falls within Schedule 1 or can be declared under s.2A. If it does, map the precise statutory pathway—survey entry (s.82), water testing (s.83A), land acquisition (s.10 + Land Administration Act 1997), or railway special Act (s.96).

For the Minister or delegates, maintain a written delegation register compliant with ss.5A, 5B and 9F; every subdelegation by another Minister must be copied to the original Minister “as soon as is practicable” (s.5B(2)). Notices of entry must be given where practicable at least 48 hours in advance and authority produced on demand (ss.82(2), 83A(3)). Damage minimisation is mandatory (s.83C(1)); contemporaneous records of negotiations under s.83C(4) should be kept to invoke the statutory bar.

BMA officers must segregate the Account (s.9E), obtain Treasurer approval for all borrowings (s.9C(2)), and ensure annual Estimates include a nominal sum (s.9E(7)). All financial transactions must comply with the Financial Management Act 2006 as applied by s.9G.

Railway proponents must table a map before second reading (s.96(2)), deposit the signed map in the Supreme Court Central Office, and stay within the deviation limits. Level-crossing protocols (ss.100–103) require physical maintenance obligations and gate management plans.

Landowners facing entry should request production of authority, document all damage within 30 days (or 12 months if no notice was given), and serve written claims promptly. Local governments receiving control of bridges under s.91 must budget for apportioned costs or risk Minister intervention and debt recovery.

Organisations should maintain an infrastructure compliance matrix cross-referencing the Act, Land Administration Act 1997, Environmental Protection Act 1986 and any special Act. Regular audits of survey-mark integrity, waste-facility licensing (s.112), and delegation currency are advisable. Because the statute integrates so many other regimes, a siloed approach is the fastest route to non-compliance; integrated legal, engineering and financial sign-off is the practical minimum standard for projects valued above a few million dollars.
