Industrial Manslaughter Queensland 2026 — WHS Lessons

The first successful industrial manslaughter Queensland conviction in the mining sector has sent a clear message to employers across Australia. In March 2026, Mastermyne Crinum Operations Pty Ltd was found guilty of industrial manslaughter by a jury at the District Court of Emerald, Queensland, following the death of experienced underground miner Graham Dawson on 14 September 2021 when the roof of the Crinum coal mine collapsed and crushed him. It took four days for his body to be recovered.

The case is the first successful application of industrial manslaughter charges in the Queensland mining sector since the laws were extended to cover the Queensland mining industry in 2020. Mastermyne has indicated it may partially mitigate any financial penalty through its insurance program. Sentencing is yet to occur.

What Happened?

Investigations by Resources Safety and Health Queensland (RSHQ) identified that Mastermyne’s strata control systems were inadequate. The company was found to have negligently caused Graham Dawson’s death, with 11 of 12 jurors finding the company guilty under Queensland’s Coal Mining Safety and Health Act.

Why This Case Matters

This conviction highlights a significant shift in how workplace safety laws are being enforced across Australia:

Stronger penalties: Industrial manslaughter offences in Queensland carry a maximum penalty of $10 million for a body corporate and up to 20 years imprisonment for an individual.
Organisational accountability: Regulators are targeting systemic failures in safety management — not just frontline incidents. Inadequate strata control systems were central to this prosecution.
Proactive risk management expected: Businesses must identify, assess and control hazards before incidents occur. Reactive responses after a fatality are insufficient.
Insurance is not a defence: Mastermyne’s suggestion that penalties may be partly covered by insurance has prompted discussion about whether insurance should be permitted to cover WHS criminal penalties — a question regulators across Australia are actively examining.

Implications for ALL Workplaces and HSRs

While this industrial manslaughter Queensland case occurred under mining-specific legislation, the implications extend nationally. Under the Work Health and Safety Act, employers have a primary duty of care to ensure the health and safety of workers so far as is reasonably practicable. Industrial manslaughter laws have now been introduced or are before parliament in most Australian jurisdictions.

For elected Health and Safety Representatives (HSRs), this case reinforces the importance of:

Actively identifying hazards — including high-risk and emerging risks
Raising concerns with management and ensuring they are formally addressed
Participating in WHS consultation and safety reviews
Understanding powers under WHS legislation to issue Provisional Improvement Notices and direct cessation of unsafe work

A Clear Message to Employers

This conviction sends a strong signal across all industries: failure to manage known risks can result in serious criminal consequences, including industrial manslaughter charges — as seen in the $275,000 electrocution prosecution and the EWP fatality prosecution.

With regulators increasing enforcement activity across both physical and psychosocial hazards, organisations must ensure their WHS systems are robust, well-documented and continuously reviewed.
