This track provides papers that address the following issues: housing affordability and its impacts on inequality, and social advantage and disadvantage; urban sprawl and associated housing and social infrastructure needs across cities and regions; homelessness, houselessness and crisis accommodation; housing system reform, and the futures of homeownership, the private rental sector, and social and community housing sectors; social and cultural diversity (gender, age, disability, Indigeneity, ethnicity, class and others) and its implications for housing and social/care infrastructures; and transformative models of housing innovation.
