Role of the department

This page is for: 

This information is designed to help WA organisations and their associated workforces (including volunteers) understand the new Work Health and Safety laws.

What is the role of the Department?

WorkSafe, part of the Department of Mines, Industry Regulation and Safety, is the WHS department that will assist the regulator in the administration of the WHS Act. This includes the provision of inspectors and other staff to secure compliance with the legislation.

To align with the legislative change the Department is consolidating all its workplace health and safety inspectorates from the existing WorkSafe, Mines Safety, Petroleum Safety, and the teams that support them, under one shared identity, WorkSafe Western Australia.

A unified identity will simplify communication about the relationship between the WorkSafe Commissioner, as the ‘regulator’ under the WHS Act, and DMIRS as the ‘WHS department’.

The new WorkSafe WA identity will assist to reinforce the message that there will be one WHS Act for almost all WA workplaces.
