The latest paper from Child Family Community Australia examines developments within Australian child protection systems since 2010. The paper details findings from a data collection survey of key agencies with responsibility for statutory child protection in all Australian states and territories and the Commonwealth Department of Social Services undertaken in November 2016. The survey sought to collect information about changes within eight system components or “building blocks” (structures, functions and capacities) as well as system principles and goals. Among key findings are that child protection systems are facing insufficient capacity to address the quantity and complexity of cases into statutory child protection and alternative care arrangements and the over-representation of Aboriginal and Torres Strait Islander children within the system. Though many changes are noted as taking place in all jurisdictions, the paper questions whether the changes will be substantial enough to address complex, multi-level systemic challenges. To facilitate transformative change, the paper recommends that continuous adaptation underpin the system, informed by a sense of collective responsibility and collaboration.
