Each year the Australasian Therapeutic Communities Association (ATCA) hosts an international conference bringing together professionals working in Therapeutic Communities, researchers and clinicians in the Alcohol and Drug (AOD) field and affiliated areas. Therapeutic Communities (TCs) are an integral element of a comprehensive response to alcohol and other drug issues in our community, nationally and internationally. The ATCA Conference reflects this and has a broad appeal to those working in the field of addiction, mental health, justice and child protection. It tackles issues of significant importance around comorbidity, youth and the health of Aboriginal and Torres Strait Islander, Mãori and Pasifika peoples.
