This is a needs assessment of substance misuse services in the Perth metropolitan area (Perth Noongar ATSIC region) for Aboriginal substance users and their families. The report was commissioned by the Noongar Alcohol and Substance Abuse Service (NASAS) to provide a guide for the service needs of their clients. The report found that the current services in Perth were not able to completely meet the needs of Aboriginal clients and further services are required in Perth, particularly residential-based programs.
