Alcohol and other drug (AOD) treatment agencies across Australia provide a range of services and support to people receiving treatment for their own drug use, as well as for their families and friends. Many types of treatment are available in Australia to assist people experiencing problematic drug use. Most aim to reduce the harm of drug use, for example, counselling, information and education, and diversion programs. Some treatments specifically aim to help clients develop skills that facilitate drug-free lifestyles and prevent relapse; these typically use abstinence-oriented interventions in a structured, substance-free setting.

In 2019–20, around 139,300 clients aged 10 and over received AOD treatment. The four most common drugs that led clients to seek treatment were alcohol (34%), amphetamines (28%), cannabis (18%) and heroin (5.1%). The median age of clients was 35 years. Early responses of AOD services to the COVID-19 pandemic are seen in the last quarter of 2019–20, impacting some treatment types and service delivery settings.
