Trauma-informed care is a growing practice approach in child and family social work. Current policy directions in out-of-home care (OOHC) in Victoria, Australia show an interest in further implementation of trauma-informed care, particularly through training for foster and kinship carers. Drawing upon findings from grounded theory research with sixteen foster and kinship carers, this article considers the application of trauma-informed practices in home-based care in the Central Highlands region of Victoria, Australia. The research reveals that whilst carers utilise principles of trauma-informed care to support children and young people, they do not always experience trauma-informed support from the wider OOHC system. This discrepancy suggests that the implementation of trauma-informed care has the potential to increase pressure on home-based carers if it is only encouraged at the interpersonal level between carers and children, without incorporating associated systems-level change. These findings propose that whilst micro-level support and training for carers are necessary and useful, it is crucial for OOHC systems to move beyond such initiatives to plan and enact macro-level reforms.
