Community housing in Australia is not-for-profit affordable housing provided by community housing organisations known as Community Housing Providers (CHPs). These organisations have varying modes of operation and structure, and different types of stock. Any budget surplus in CHPs must be used to maintain existing housing, to provide better services for tenants or to help finance new properties. Although independent, the CHPs are regulated by the state, and commonly receive public funding. Most of their stock is owned by public housing authorities (SHAs) in each State, and the CHPs manage the tenancies using the rent received from tenants.
