Diversifying housing supply in response to changing demographic profiles and declining housing affordability has become a significant policy aspiration in Australia’s major cities.

However, despite this aspiration, the majority of housing is delivered in the form of detached housing in greenfield locations and, to a lesser extent, high-rise apartments, both of which are sold at market rates to owner-occupiers and small-scale buy-to-let investors.

In this context, this study engaged the expertise of 50 housing and built-environment professionals in Sydney, Melbourne and Perth on investigative panels to examine barriers and challenges within the housing system for delivering housing supply that is more diverse in terms of size and built form, tenure, development model and, importantly, affordability level.

Across these three cities, the housing industry and built-environment experts who took part in the study perceived a need for: greater diversity in housing types and sizes, particularly in lower-density suburban areas; medium- and higher-density housing forms able to accommodate a wider variety of household types and lifestyle preferences; rental housing that can offer greater security of tenure; and, more housing supply across tenures that is affordable to very low to moderate income households.
