Cameron Cox shares his experience implementing a risk-based health and safety strategy on Sydney Metro West, Australia's largest public transport project. Some key challenges included industry not being ready for the strategy and doubts that suppliers would comply. Safety priorities included public safety, rail safety, heavy vehicles, and occupational health with a focus on critical risks. Over 500,000 truck movements were required for construction, so strategies were implemented for safer vehicles, occupational hygiene, and health monitoring. Cox learned to understand change impacts, balance collaboration and accountability, and consult industry and regulators.
