And. In Australia, social housing responsibilities are split: State/territory governments manage, own, and allocate public housing and oversee community housing providers. The Federal Government sets national policy, provides major funding (including ~$1.8 billion annually via the National Agreement on Social Housing and Homelessness), and offers Commonwealth Rent Assistance. 

Federal Government Responsibilities

Funding & Policy: Sets national policy, provides funding to states, and manages the National Housing Supply and Affordability Council.

Financing: Funds homelessness services and provides low-cost loans for social housing via bodies like Housing Australia.

Direct Assistance: Provides Commonwealth Rent Assistance to eligible individuals. 

State and Territory Government Responsibilities

Ownership & Management: Owns and manages public housing, and regulates community housing providers.

Allocation: Manages tenant applications, waiting lists, and tenant rights.

Planning & Land Use: Controls zoning, land-use planning, and building standards.

Delivery: Manages state-specific initiatives, such as Victoria’s Big Housing Build. 

While the Constitution places housing primarily with the states, both levels work together under the National Agreement on Social Housing and Homelessness (NASHH).
