This study provides evidence of a decline in suicide rates among Australian construction workers over the last two decades; this decline may be attributable to the combined effects of population-wide, male-specific, and sector-specific suicide prevention efforts over this same period, suggesting that the continuation or expansion of such efforts may lead to further declines.

This research aims to identify the most suitable sustainable construction method for high-rise building construction in Australia; results show that the off-site construction method and robotic construction technique significantly improve the construction performance of high-rise construction in Australia.

Wages and research and development expenditure were found to drive construction productivity at the national level and expenditure on research and development and the number of apprentices were found to be drivers of construction productivity in Victoria, New South Wales and Western Australia.
