Join ATCA members, sector partners, government representatives and special guests as we celebrate ATCAs 40th Anniversary. This special anniversary event will include afternoon tea, anniversary cake, reflections and stories from across the sector, providing an opportunity to honour the people, services and communities who have shaped ATCA’s journey, recognise the impact of Therapeutic Communities, and look ahead to the future.

Our 40th Anniversary will be held after our 2026 Symposium from 3-5pm at one of ATCA’s founding members, WHOS, on the beautiful grounds of their TC programs in Lilyfield, on Wangal Country.
