May marked a significant milestone for the Australian coal industry: 150 years since Check Inspectors – now known as Industry Safety and Health Representatives (ISHRs) and Site Safety and Health Representatives (SSHRs) – were first legislated in NSW. As the world’s longest continuous form of worker-elected safety representation, Check Inspectors remain a cornerstone of mine safety.
In the 19th century, coal mining in Newcastle and the Hunter Valley was physically demanding, dangerous and often fatal. Drawing on a model developed in British coalfields, early mining unions in the Hunter campaigned for similar protections. Their efforts led to the Coal Mines Regulation Act of 11 May 1876, which allowed workers to elect ‘workmen inspectors’ – the forerunners of today’s Check Inspectors. This reform embedded the principle that workers themselves must have a direct, empowered role in ensuring safety underground.
Check Inspectors were experienced miners, elected by their peers to act as independent safety authorities. Many had worked in Britain and brought valuable knowledge from a more mature industry. Crucially, they were given the power to stop unsafe work – a defining feature that transformed workplace culture. This authority not only prevented harm but also gave workers confidence to speak up, knowing their concerns would be heard and acted on.
From the 1890s onwards, the NSW model spread across Australia. Similar systems were adopted in Queensland, Western Australia, Tasmania and Victoria, often propelled by union advocacy and lessons from major incidents. Over time, the role evolved into today’s ISHRs and SSHRs – highly trained statutory officials with formal powers to inspect, investigate and enforce safety standards. Their independence remains essential: they provide oversight of operations, identify hazards, and intervene when safety is compromised.
To mark the 150th anniversary, the Mining and Energy Union (MEU) commissioned leading safety expert Professor Michael Quinlan to examine the history and impact of the Check Inspector system. The project involved extensive interviews across Australia with ISHRs, SSHRs, workers, regulators and safety professionals from other industries.
The findings were clear. At sites with limited or no worker safety representation, employees reported fear of victimisation for raising concerns, weak consultation processes, and hazards left unresolved. In some cases, particularly in the NSW metalliferous sector, workers said speaking up put a “target on their backs” – a sign of a culture driven by fear rather than safety.
By contrast, operations with active ISHRs and SSHRs demonstrated stronger safety cultures. Workers felt more confident raising issues, and there was greater collaboration between management, regulators and the workforce. While the power to stop work is used sparingly, it is applied responsibly and backed by regulators when exercised. This authority acts as a critical safeguard, ensuring that production pressures never override safety.
The report also found that the presence of ISHRs improves core safety practices, including incident reporting, risk assessment and hazard control. Often, the mere presence of an independent representative leads to earlier resolution of issues, reinforcing accountability across the workplace.
Importantly, Professor Quinlan recommended extending the ISHR model beyond NSW and Queensland into other coal and metalliferous industries, such as Western Australia, Tasmania and Victoria.
After 150 years, the Check Inspector system stands not only as a historic achievement but as a global benchmark for worker-led safety. It demonstrates that empowering workers is one of the most effective ways to prevent harm. Every time a worker raises a concern or stops unsafe work, they contribute to this enduring legacy.
This month, site and distrcit Check Inspectors will gather in Rockhampton to share expereinces and learn from experts about upholding safety standards across Queensland coal mines.
On this anniversary, we acknowledge the dedication of ISHRs and SSHRs across the country. Their commitment – often behind the scenes – helps ensure that Australia’s mines are safer, healthier and more accountable workplaces.
