New research shows tunnel workers remain exposed to significant silica dust risks

Today’s story in the Sydney Morning Herald highlights that workers are still being exposed to hazardous dusts and entirely preventable dust diseases – and the human cost is considerable.

A Sydney Morning Herald investigation has highlighted the experience of Hamish Studholme, a tunnelling worker on major infrastructure projects for over 20 years whose employers spoke the language of safety, yet he was diagnosed with silicosis – a currently incurable lung disease – in 2023. Hamish is a valued member of our ADDRI Silicosis Consumer Group, contributing his lived experience to our work, and his story unfortunately reflects what too many families already know: when safety systems are not in place or enforced, there are damaging consequences on people’s health and livelihoods.

New research published today by the University of Sydney and led by Kate Cole OAM shows tunnel workers reporting significant silica dust exposure risks across major infrastructure projects. The survey of 290 tunnelling workers and industry professionals found that while workers are well aware of the risks, protections are falling short. As she noted: “Workers understand the risks, but the survey results indicate that systems in place are not consistently protecting them. This is not a knowledge gap: it’s a failure of leadership, accountability and enforcement, with workers ultimately paying the price with their health.”

We know that dust diseases are preventable – and safe working conditions should be of the highest priority. At ADDRI, we’re working alongside workers, researchers, government and industry to help turn evidence like this into prevention – stronger protections, earlier detection, real accountability and ongoing support for those who have been impacted.
