Overview of the Act Overview of the general regulations

Modernising work health and safety in Western Australia

In 2017, work started on developing modernised work health and safety (WHS) laws in Western Australia. To be more consistent with the rest of Australia, the new laws will largely be based on the national model Work Health and Safety Act (the model WHS Act).

Changes to the laws also mean that there will only be one Act for workplace safety and health across all WA industries.

The Act will be supported by three sets of industry specific regulations to suit WA’s unique conditions. These regulations will help the resources sector continue to use a risk-based approach, and support the safety-case approach for petroleum.

Work Health and Safety Act

Western Australia’s Work Health and Safety Act 2020 (WHS Act) was passed by the Parliament in early November 2020 and assented to by the Governor on 10 November 2020.

When implemented in 2022, almost all Western Australian workplaces will come under this single Act, which will replace the following legislation:

There has been extensive public consultation in developing the Act – find out about the Act consultation process.

Work Health and Safety Regulations

On 11 March 2021, the Hon Mark McGowan MLA, Premier, announced his commitment to implementing the three sets of regulations related to the new WHS Act from January 2022.  The Department of Mines, Industry Regulation and Safety (DMIRS) is working to meet this Government commitment. 

It is expected that in mid-September 2021, DMIRS will commence promoting advice, providing information and delivering education regarding the new WHS laws.

Information about the WHS laws will also be provided during October’s Safe Work Month

The WHS Act will be supported by three sets of regulations:

  • Work Health and Safety Regulations (General) – applies to all workplaces except those covered by the other two sets of regulations 
  • Work Health and Safety Regulations (Mines) – applies to exploration and mining operations
  • Work Health and Safety Regulations (Petroleum and Geothermal Energy Operations).

Once the regulations are completed, the WHS Act and its regulations will come into force.
