People who have lived in child welfare institutions and other substitute care as children are known to have suffered significant abuse and disadvantage in their life course. There is international concern about the trauma and victimisation many of them experienced while in care and the significant and lifelong impacts of abuse in care. This presentation reports research which examines the in-care and post-care experience of people who lived in Australian child welfare institutions and other substitute care as children between 1930‒1989. The research utilised a mixed-methods design which included surveys, interviews, and focus groups, the sample comprising 700 respondents across Australia. This presentation will report specifically on the experience of the former Child Migrant cohort within the study.
