There is much research to suggest a considerable overlap between people experiencing precarious housing, and drug and alcohol misuse. Linking client data from specialist homelessness services and alcohol and other drug treatment services, this report provides a picture of the intersection of these two issues on a national scale. It reveals a vulnerable population, in which Indigenous Australians and experiences of domestic and family violence and mental health issues were all over-represented. Their poorer drug treatment and housing outcomes highlight the level of difficulty faced in assisting these people to achieve long-term outcomes.
