In the nearly two decades since the last Australian Housing Survey there have been significant changes in the housing system – and there is now a vocal call from researchers and policy makers for a systematic, reliable and nationally representative dataset of housing conditions. This LIEF Project will develop, collect, and make available, an Australian Housing Conditions Data Infrastructure. It will provide a foundation of tools, data and protocols to that Australian researchers and policy makers urgently need to deliver productivity, growth and a healthier population.
