Victorian coroner finds fatalities of workers in Ballarat trench collapse were avoidable

Victorian Coroner Finds Fatalities of Workers in Ballarat Trench Collapse Were Avoidable

A Victorian coroner has determined that fatalities of two men, who perished as a result of a trench collapse in Ballarat in 2018, could have been avoided. Findings confirm what many safety professionals suspected from the outset: these deaths were preventable.

What Happened in Winter Valley

Men died when a trench being excavated in Winter Valley caved in on March 21, 2018. During that period, both individuals were working on a site project for a civil construction firm.

Relatives of the two workers sought a coronial inquest in late 2018. Primary emphasis of the inquest centred on analysing the response to rescue services deployed after the trench collapse.

Criminal Case and Workplace Safety Breach

Following a criminal case in 2023, the construction company was fined over $500,000 after a director admitted guilt regarding a breach of workplace safety protocols. This outcome reinforces why robust OHS systems remain essential across civil construction sites, particularly where excavation and trenching services are involved.

Coroner's Findings on Emergency Response

Recent findings published by the Victorian coroner indicated no evidence to suggest that the decision made by emergency services to employ an excavator during recovery "caused or contributed" to deaths of either individual.

This distinction matters for safety professionals. Rescue services acted appropriately once collapse occurred — the preventable failure lay upstream, in site planning and OHS compliance before excavation began.

Why Trench Collapse Incidents Remain Preventable

Ballarat's tragedy sits alongside a troubling pattern across Australia. Similar incidents, including a Queensland mine collapse, highlight recurring gaps in excavation safety planning nationwide.

Employers must ensure comprehensive risk assessments, shoring plans, and emergency response procedures are documented before any trenching work commences. An Excavation Collapse Emergency Response Plan helps site managers prepare for worst-case scenarios rather than react to them.

Sites requiring high-risk excavation work should also consider whether a Safe Work Method Statement is legally required — in most trenching scenarios, one is.

Broader Context: OHS Enforcement Across Australia and New Zealand

Trench collapses aren't isolated to Victoria. Regulators across the region continue investigating similar failures, such as when WorkSafe investigated an Auckland trench collapse, demonstrating that excavation hazards demand consistent vigilance regardless of jurisdiction.

Victoria has also strengthened protections for workers on other fronts, including new regulations protecting Victorian workers from harassment, signalling a broader commitment to comprehensive workplace safety reform.

Key Takeaways for Safety Professionals

• Coroner confirmed Ballarat trench collapse deaths were preventable, not a result of rescue services' actions.
• Construction firm faced substantial fines following an OHS breach admission in 2023.
• Emergency services' use of excavator during recovery was found unrelated to the fatalities.
• Robust site-specific OHS planning and documented emergency response procedures remain critical controls against trench collapse risk.
