March 29, 2026Anglo Coal Acquitted: When Coal Mine Safety Prosecutions Fall Apart (And What It Means for Workers)
Table of Contents
A worker is killed underground. A major mining company is charged. A conviction is handed down. Then, seven years later, the company walks free because the prosecution offered no evidence at retrial.
This is not a hypothetical. This is exactly what happened in Anglo Coal (Moranbah North Management) Pty Ltd v Stone (No 3) ICQ 003, decided by the Industrial Court of Queensland on 17 March 2026. If you work in coal mine safety, mine site management, or WHS compliance in Queensland, this case should concern you deeply.
A Worker Died. Four Others Were Injured. Here Is What Happened.
On 20 February 2019, Bradley Hardwick, a 47-year-old equipment operator at the Moranbah North underground coal mine in central Queensland, was killed when a Cat 120 Anderson Wright Grader exiting the underground mine rolled down the drift and collided with a man transporter carrying workers. Four other mine workers, Vincent Wilson, John Jones, Craig Banks, and Mark Barnham, sustained injuries in the collision.
Anglo Coal (Moranbah North Management) Pty Ltd operated the Moranbah North Mine at the time of the incident. Anglo American confirmed the death and suspended mine operations while an investigation was conducted. The mine employs over 600 workers and is one of Queensland’s major coking coal producers.
Following the incident, the Office of Work Health Safety Prosecutor charged Anglo Coal with a serious coal mine safety offence under the Coal Mining Safety and Health Act 1999 (Qld), alleging the company failed to discharge its safety and health obligations under section 41(1)(a), in contravention of section 34 of the Act. The charge included aggravating circumstances, namely that the breach caused the death of Bradley Hardwick and bodily harm to four other workers.
From Conviction to Acquittal: A Seven-Year Legal Saga
The charge was prosecuted in the Industrial Magistrates Court, which convicted Anglo Coal of the offence and found the aggravating circumstance of bodily harm to Wilson, Jones, and Barnham was proven. However, the Magistrate did not find the prosecution had proven the aggravating circumstance relating to the death of Bradley Hardwick or injury to Craig Banks.
Anglo Coal appealed the conviction. In Anglo Coal (Moranbah North Management) Pty Ltd v Stone ICQ 011, the Industrial Court of Queensland held that the trial had miscarried. The conviction was suspended and the matter was remitted back to the Industrial Magistrates Court for a retrial before a different magistrate.
In August 2025, the Industrial Court made orders directing the Industrial Magistrates Court to determine the charge, refer findings back, and crucially, not to acquit Anglo Coal on its own even if a not-guilty finding was made.
The retrial came before the Industrial Magistrates Court on 6 March 2026. Anglo Coal entered a plea of not guilty. The Office of Work Health Safety Prosecutor then offered no evidence whatsoever in support of the prosecution.
The Industrial Magistrate had no choice but to record a not-guilty finding. The matter was referred back to the Industrial Court of Queensland. On 17 March 2026, the Industrial Court set aside the conviction and formally acquitted Anglo Coal of the charge. No costs were ordered.
A worker was dead. A family was left without answers. And the mining company faced zero legal consequences.
How Did a Coal Mine Safety Prosecution Collapse Like This?
This is the question that every safety professional, mine worker, union representative, and mining regulator in Queensland needs to ask.
Coal mine safety prosecutions are not simple. They involve specialist legislation, complex evidentiary requirements, and multiple layers of appellate review. When a trial miscarries at the first instance, it does not automatically mean the accused is innocent. It means something went wrong with the process, and the system is obligated to retry the matter properly.
What happened here was that following the retrial order, the prosecution chose not to run the case again. The reasons for this decision have not been made public. It may relate to the passage of time (seven years from incident to acquittal), witness availability, evidentiary challenges, or a prosecutorial assessment that the case could not be proven beyond reasonable doubt on retrial.
But the result is the same: a category 2 coal mine safety breach, allegedly causing the death of a worker and injuries to others, ended with no conviction, no fine, and no accountability recorded against the operator.
This is not an isolated pattern in Australian WHS law. For more examples of how mining and workplace safety prosecutions play out across Australia, visit the HSE Direct Industry News page where we track significant cases and regulatory changes across all states and territories.
What Section 41 of the Coal Mining Safety and Health Act Actually Requires
Understanding why this charge was brought requires understanding what section 41 of the Coal Mining Safety and Health Act 1999 (Qld) actually demands of mine operators.
Section 41(1)(a) imposes a safety and health obligation on the operator of a coal mine. That obligation requires the operator to ensure, so far as is reasonably practicable, that the mine is operated safely and that the health of persons at the mine is not affected. This is not a soft duty. It is an affirmative legal obligation backed by serious criminal penalties.
Contravention of section 34 of the Act, which relates to the failure to discharge a safety and health obligation, carries significant penalties. Where the contravention is accompanied by aggravating circumstances such as death or serious bodily harm, the penalties increase substantially.
The Coal Mining Safety and Health Regulation 2017 (Qld) supplements these obligations by requiring mine operators to maintain robust safety and health management systems that include risk identification, hazard analysis, hazard management and control, and incident reporting systems. The regulation also imposes specific vehicle safety obligations on mine operators, requiring systems that govern the safe operation of mobile plant including graders, personnel carriers, and other heavy equipment used underground.
Anglo Coal was charged with failing to meet these obligations. The prosecution alleged that failure caused a man’s death. The acquittal does not erase that allegation. It simply means the legal system was unable to finalise accountability.
Mobile Plant: The Silent Killer in Coal Mine Safety
The 2019 Moranbah North incident was a mobile plant incident. A grader collided with a personnel carrier underground. This type of incident is one of the most consistently documented causes of death and serious injury in the Australian coal mining industry.
Mobile plant on mine sites, including graders, haul trucks, light vehicles, loaders, and personnel carriers, operates in confined, high-traffic, and low-visibility environments. The risks are compounded underground where dust, lighting, gradient changes, and multiple vehicle movements intersect.
WorkSafe Queensland’s guidance on working in and around mobile plant makes clear that exclusion zones, traffic management plans, and structured training are not optional extras. They are the baseline of a functioning coal mine safety system.
The Queensland Mines Inspectorate flagged the Moranbah North incident in a specific alert relating to hydraulic braking systems. This means the regulator identified a systemic plant failure risk that could recur at any Queensland coal mine without appropriate controls.
If your mine site or contractor workforce operates mobile plant, including graders, dozers, loaders, or haul trucks, you need documented operational standards. HSE Direct’s Mobile Plant Operational Standard provides a ready-to-deploy framework covering pre-start checks, exclusion zones, traffic management, operator competency requirements, and incident response procedures tailored to Australian regulatory requirements.
What This Case Means for Coal Mine Safety in Queensland
The acquittal of Anglo Coal does not create legal precedent that makes it easier for mine operators to avoid prosecution. It does, however, expose three critical vulnerabilities in the coal mine safety enforcement system that safety professionals need to understand.
First, prosecutions take too long. Seven years elapsed between the incident and the final acquittal. Witnesses age, evidence degrades, memories fade, and the evidentiary foundation of a complex prosecution weakens with every year of delay. Any coal mine safety prosecution that takes a decade to resolve is a prosecution that risks collapsing under its own timeline.
Second, a miscarried trial is not a death sentence for prosecution. The decision to offer no evidence on retrial was a prosecutorial choice. It was not a legal inevitability. When a trial miscarries due to procedural error, the prosecution retains the ability to re-run the case. The failure to do so here means no court ever formally assessed Anglo Coal’s culpability for Bradley Hardwick’s death.
Third, the aggravating circumstance of death was never proven. Even at the original conviction, the Magistrate declined to find that the breach caused Bradley Hardwick’s death. This is significant. It means the legal system never recorded a judicial finding that a coal mine operator’s failure caused a fatality at Moranbah North Mine.
For mine operators, safety managers, and WHS advisors operating under the Coal Mining Safety and Health Act 1999, none of this provides comfort. The obligation under section 41 remains absolute. Operators who believe that slow-moving prosecutions represent low risk are making a dangerous miscalculation.
The Bigger Picture: Coal Mine Safety Accountability Cannot Depend on Prosecution Alone
Bradley Hardwick went to work on 20 February 2019 and never came home. Three other workers were seriously injured. Seven years later, no court has ever convicted the operator responsible for running the mine where he died.
This is not a criticism of the court. The Industrial Court of Queensland followed the law precisely. The acquittal in Anglo Coal (Moranbah North Management) Pty Ltd v Stone (No 3) ICQ 003 was legally correct based on the absence of evidence presented at retrial.
The problem is systemic. Coal mine safety in Queensland, and across Australia, cannot rely on the threat of prosecution as its primary accountability mechanism when prosecutions take seven years, collapse on retrial, and leave workers’ families without answers.
Proactive compliance, robust safety and health management systems, genuine risk management, and a coal mine safety culture that does not wait for a regulator to arrive are the only mechanisms that actually protect lives underground.
The Coal Mining Safety and Health Act 1999 places the obligation on operators to ensure, so far as is reasonably practicable, that their mines are safe. That obligation exists whether or not a prosecution ever follows a failure to meet it.
Bradley Hardwick deserved better. So do the 600-plus workers who go underground at Moranbah North every single day.
