While it is estimated that 621,300 persons suffer work related injury each year in Australia, very little is known about what proportion of such accidents are directly attributed to the effects of alcohol or other drugs, particularly within the construction industry. This project aims to enhance the safety of all workers in the Australian building and infastructure workforce, by firstly gaining a greater understanding into the effects interventions to improve safety outcomes within the industry. A change in culture towards improving safety, in the industry, through a nationally collaborative effort is the expected outcome.
