WHS Act Compliance for Australian Mines: How the Model Act and Mining Regulations Work Together

Compliance for Australian mines sits on three layers. The first is the Model WHS Act, adopted by most states and territories. The second is state-specific mining regulation. The third is the site safety management system that the operator is required to maintain.

The state picture is uneven. New South Wales operates under the Work Health and Safety (Mines and Petroleum) Regulation 2022. Western Australia has moved to the WHS (Mines) Regulations 2022. Queensland regulates under the Coal Mining Safety and Health Act 1999 and the Mining and Quarrying Safety and Health Act 1999, both of which pre-date the Model Act and remain in force. Victoria continues to use its OHS Act 2004 with mining-specific regulations.

All of these require principal mining hazards to be documented and managed through a written hazard management plan. Inspection regimes flow from the hazard management plan, with frequencies and methodologies driven by risk classification.

For overseas operators entering the Australian market, two practical points matter. First, the regime is layered, federal model, state law, and site management, and a compliance gap at any level is an exposure. Second, the documentation expectations are demanding, and digital inspection records are increasingly the standard for demonstrating ongoing compliance.
