WA SWMS requirements: Ensure your SWMS documentation meets current WorkSafe WA standards
Western Australia was the last mainland Australian state to adopt the harmonised Work Health and Safety laws, with the Work Health and Safety Act 2020 (WA) and Work Health and Safety (General) Regulations 2022 (WA) coming into effect on 31 March 2022. Administered by WorkSafe WA — a division of the Department of Energy, Mines, Industry Regulation and Safety (DEMIRS) — the new framework replaced the previous Occupational Safety and Health Act 1984. For businesses that operated under the old OSH Act framework, understanding the changes introduced by the WHS Act 2020 is essential for maintaining compliance.

Western Australia Work Health & Safety Overview
Western Australia adopted the harmonised Work Health and Safety laws on 31 March 2022 through the Work Health and Safety Act 2020 (WA) and Work Health and Safety (General) Regulations 2022 (WA), administered by WorkSafe WA (DEMIRS). As the last mainland state to adopt harmonised laws, WA's transition introduced significant changes for businesses previously operating under the OSH Act 1984. The state's unique industrial profile — combining metropolitan Perth construction with large-scale remote resources construction — creates distinct safety management challenges. Mining safety remains separately regulated by the Mines Safety Inspectorate under the Mines Safety and Inspection Act 1994.

Western Australia completed its transition to harmonised WHS laws on 31 March 2022, aligning with the Model Work Health and Safety laws adopted by most other Australian states. The Work Health and Safety Act 2020 (WA) and the Work Health and Safety (General) Regulations 2022 (WA) replaced the Occupational Safety and Health Act 1984 and OSH Regulations 1996. WorkSafe WA, operating under DEMIRS, is the state regulator responsible for compliance and enforcement.
WorkSafe WA Authority and Scope
WorkSafe WA regulates workplace safety across all non-mining industries in Western Australia, including construction, manufacturing, retail, hospitality, agriculture, and services. Mining safety in Western Australia is regulated separately by the Mines Safety Inspectorate under the Mines Safety and Inspection Act 1994. This dual-regulator structure means businesses operating in the resources construction sector must understand obligations under both frameworks.
Key Legislation Framework
Work Health and Safety Act 2020 (WA) — Primary legislation establishing duties of care for PCBUs, officers, workers, and other persons, effective from 31 March 2022. Work Health and Safety (General) Regulations 2022 (WA) — Specific requirements including SWMS for high-risk construction work. Work Health and Safety (Mines) Regulations 2022 (WA) — Mining-specific safety requirements. Mines Safety and Inspection Act 1994 — Additional requirements for mining operations.
WA SWMS Requirements: Mandatory Documentation
The Work Health and Safety (General) Regulations 2022 (WA) mandate Safe Work Method Statements for all high-risk construction work carried out in Western Australia. The requirements are broadly consistent with the Model WHS laws, with some WA-specific features reflecting the state's unique industrial environment.
High-Risk Construction Work Definition
Under WA WHS Regulations 2022, high-risk construction work includes: work involving a risk of a person falling 2 metres or more; demolition of a structure; work on or adjacent to a road or railway used by traffic; work in confined spaces; work in or near a shaft or trench deeper than 1.5 metres; work on or near pressurised gas mains; work involving disturbance of asbestos-containing material; and work involving explosives. WA's large-scale mining construction also involves additional obligations under the Mines Safety framework.
SWMS Content Requirements
A WA SWMS must identify the type of high-risk construction work, identify all reasonably foreseeable hazards, describe the measures to control those hazards, and describe how control measures will be monitored. Worker consultation is mandatory under the WHS Act 2020 (WA), and SWMS must be prepared in consultation with workers who will carry out the work. The principal contractor must ensure SWMS are prepared before work commences and are maintained on site.
Transition From OSH Act: Key Changes
Businesses that operated under the previous OSH Act 1984 framework need to be aware of key changes under the WHS Act 2020. These include the new PCBU concept (replacing 'employer'), stronger officer due diligence obligations, expanded right of entry for WHS representatives, and updated worker consultation requirements. SWMS obligations under the new framework are broadly similar to those under the old system but with updated terminology and consultation requirements.
WorkSafe WA Penalties: Enforcement Overview
WorkSafe WA enforces significant penalties under the WHS Act 2020 for SWMS non-compliance. The harmonised laws introduced category-based offences with higher maximum penalties than the previous OSH Act framework, reflecting the national trend toward stronger WHS enforcement.
Penalty Levels
Significant individual and corporate penalties apply for WHS breaches in Western Australia under the WHS Act 2020. Category 1 (most serious), Category 2, and Category 3 offences exist, with Category 1 involving exposure to a risk of death or serious injury. Officers can be personally prosecuted for Category 1 and 2 offences. Refer to WorkSafe WA for current penalty unit amounts.
Enforcement Trends
WorkSafe WA has been updating its enforcement approach following the transition to the WHS Act 2020. The regulator has indicated increased attention to SWMS compliance as part of its construction safety focus. WA's significant mining and resources construction sector creates unique enforcement challenges, with coordination between WorkSafe WA and the Mines Safety Inspectorate for projects spanning both frameworks.
SWMS Non-Compliance: Real Consequences
Construction companies across Western Australia have faced improvement notices, prohibition notices, and prosecutions for SWMS failures under both the old OSH Act and the new WHS Act 2020 framework. Common areas of enforcement include falls from height on residential construction, inadequate confined space procedures on resources-related projects, and demolition documentation for Perth's urban renewal areas.
Western Australia Construction Industry Overview
Western Australia's construction industry is unique in Australia, driven heavily by the mining and resources sector alongside metropolitan residential and commercial construction in Perth. The state's boom-and-bust economic cycles, driven by global resources demand, create significant variability in construction activity and workforce movement.
Industry Scale and Workforce
Western Australia's construction sector spans metropolitan Perth construction, resources-related construction at project sites across the state's remote regions (Pilbara, Kimberley, Goldfields), and regional centre construction in Bunbury, Geraldton, Kalgoorlie, and Broome. The resources construction sector often involves fly-in/fly-out (FIFO) workers, creating additional safety management challenges.
Safety Performance
Common workplace incidents in WA construction include falls from height, being struck by objects, and incidents associated with remote location construction including heat, isolation, and fatigue. The resources-related construction sector has historically had higher injury rates than metropolitan construction, reflecting the challenging environments in which work is performed. Refer to WorkSafe WA and the Mines Safety Inspectorate for current safety performance data.
Regional Distribution
Construction activity is concentrated in the Perth metropolitan area, with significant remote project construction in the Pilbara (iron ore and LNG projects), Kimberley (pastoral and tourism infrastructure), Goldfields (gold mining projects), and South West (agriculture and energy). Resources project construction often involves large-scale temporary accommodation and associated infrastructure.
