This is the seventh report on Specialist Homelessness Services from the AIHW which describes the characteristics of clients of specialist homelessness services (SHS), the services requested, outcomes achieved, and unmet requests for services during 2017–18. Two hundred and eighty eight thousand eight hundred clients were assisted by SHS agencies in 2017-18. Four in ten clients were homeless when they presented to a SHS agency. Aboriginal and Torres Strait Islander people were more likely than non-Indigenous Australians to experience insecure housing, live in overcrowded dwellings and experience homelessness, including intergenerational homelessness. They continue to be over-represented in both the national homeless population and as users of specialist homelessness services. While Aboriginal and Torres Strait Islander people make up 3.2% of the Australian population they made up 25% of the clients assisted by specialist homelessness services in 2017–18. For persons who had left care in 2017-18, two in 5 (41%) sought assistance as they were transitioning from foster care, child safety residential placements or other care arrangements.
