Multi-Sectoral Systems Approach (MSSA) to Addressing Australian Social and Affordable Housing Challenges and Solutions: White Paper No. 1

Australia’s housing crisis demands a coordinated, multi‑sectoral systems approach that integrates policy, finance and physical infrastructure to accelerate the delivery of social and affordable housing. Drawing on insights from a national think tank, this white paper analyses the physical, communal and economic barriers shaping the crisis and outlines practical, cross‑sector strategies—from modular construction and land‑use reform to Build‑to‑Rent models, community‑centred design and diversified investment pathways. It argues that systemic reform, strategic partnerships and short‑term delivery frameworks are essential to unlocking dormant supply, improving tenure security and creating a more equitable, sustainable housing system for all Australians.
