What is this right?
Under the Work Health and Safety (WHS) Act 2011, your employer — known in the statute as a PCBU (Person Conducting a Business or Undertaking) — owes a primary duty of care to ensure health, safety, and welfare at work so far as is reasonably practicable. The reasonably-practicable qualifier is what most disputes turn on.
The PCBU has to:
- Provide a safe environment, safe equipment, and adequate training.
- Identify and manage risks to health and safety.
- Provide adequate facilities — toilets, drinking water, first aid.
- Consult with workers on safety matters that affect them.
Workers can elect Health and Safety Representatives (HSRs). HSRs can issue Provisional Improvement Notices (PINs) and direct a cease-work where there is a serious and immediate risk — a real power, not a symbolic one.
You also have the personal right to cease or refuse unsafe work on a reasonable concern of serious risk. Refusal under the WHS Act is protected; retaliation against it is unlawful.
Respect@Work positive duty (Sex Discrimination Act, AHRC enforcement from 12 December 2023): on top of WHS duties, employers now have a positive duty to prevent workplace sexual harassment, sex-based harassment, hostile workplace environments, and victimisation. This is not a duty to respond after the fact — it is a duty to take reasonable steps in advance. The Australian Human Rights Commission can issue compliance notices, enter into enforceable undertakings, and apply to the Federal Court for enforcement. The shift from a complaint-only model to a positive duty puts the obligation on the employer to set up training, reporting channels, and culture — long before any incident.
When does it apply?
- You are a worker — this includes employees, contractors, subcontractors, apprentices, volunteers, and work experience students.
- The WHS Act applies to Commonwealth workplaces directly and has been adopted as model law by every state and territory except Victoria (which has its own OHS Act) and Western Australia (which adopted it in 2022).
What to Do If Your Australian Workplace Is Unsafe or Ignoring Safety Hazards
- Report any hazard to your supervisor or Health and Safety Representative immediately.
- If there is a serious risk, you may cease work — tell your employer straight away and stay at the workplace.
- Report serious incidents (death, serious injury, dangerous incidents) to Safe Work Australia or your state/territory regulator immediately.
- If your employer retaliates, lodge a general protections claim with the Fair Work Commission.
What should you NOT do?
- Don't ignore safety concerns — even small hazards can lead to serious injuries.
- Don't assume raising safety issues will get you fired. The law protects you from retaliation under the adverse action provisions of the Fair Work Act (s 340-352).
- Don't tamper with or remove safety equipment — workers have a duty to comply with reasonable safety instructions.
How Western Australia differs from federal law
WA adopted the national model Work Health and Safety Act 2020 (WA), which commenced on 31 March 2022 — making WA the last state to adopt the model WHS laws. The Act is enforced by WorkSafe WA, a division of DMIRS.
- WorkSafe WA regulates workplace safety across all industries in WA. The adoption of the model WHS Act brought WA into alignment with most other states, replacing the Occupational Safety and Health Act 1984.
- Workers' compensation in WA is governed by the Workers' Compensation and Injury Management Act 1981 (WA). Unlike Queensland's monopoly insurer model, WA has a competitive private insurance market for workers' compensation, regulated by WorkCover WA.
- WA has separate mining safety legislation — the Mines Safety and Inspection Act 1994 (WA) (transitioning to the WHS Act framework) regulates safety in the state's massive mining and resources sector, enforced by DMIRS's Mines Safety directorate.
- Disputes over workers' compensation in WA are heard by WorkCover WA's Conciliation and Arbitration Services and can be appealed to the District Court.
Additional Steps in Western Australia
Report unsafe workplaces to WorkSafe WA (1300 307 877 or dmirs.wa.gov.au/worksafe). Lodge workers' compensation claims through your employer to their insurer, regulated by WorkCover WA (workcover.wa.gov.au). For disputes, contact WorkCover WA's conciliation service. Free advice from the Employment Law Centre of WA.
