Therapeutic Residential Care (TRC) has attracted increasing interest in Australia, as a specialised out-of-home care option for children with complex needs. Extending beyond the limitations of traditional residential programmes, TRC aims to address the impact of trauma and promote positive development and wellbeing. The Lighthouse Foundation is a not-for-profit organisation based in Melbourne, providing a long-term programme of TRC to young people aged 15 to 22 at intake. The organisation has developed an attachment and trauma-informed therapeutic community approach, embodied in the Therapeutic Family Model of Care. This discussion paper explores how the therapeutic community approach taken by Lighthouse provides a different experience of the cultural ‘sites’ in which early traumatic experiences occur – including the home environment, experiences of family, and the wider community. In doing so, we propose that an important dimension of TRC is the capacity to challenge traumatic relational blueprints of abuse and neglect. This, in turn, supports children to form and sustain positive and reciprocal relationships, and to live inter-dependently in the community.
