Children with disabilities in out-of-home care (OOHC) are an overrepresented group in Australia, yet little is known about their circumstances, needs, and experiences within OOHC. Utilising a systematic scoping review methodology, we explored the state of knowledge about the experiences of children and young people with a disability in out-of-home care in Australia. Findings in this review speak to the unmet needs and challanges that children with disabilities face in child welfare systems and how systemic failures can lead to institutional pipelines of further maltreatment, adversity, and marginalisation. The review discusses the key themes in the literature, including (i) compounding trauma and placement failures, (ii) concerns of safety, stability, and neglect, (iii) limited control and choice, and (iv) disability and multisystem involvement.
