This article traces the history of child welfare in Australia, showing the ways in which policies and practices, deriving primarily from Britain, were adopted and adapted in a nation in which jurisdiction was split between colonies/states and further divided, within states, on the basis of race. It argues that child welfare has always been part of the nation-building project, central to national objectives when children could be constructed as future citizens, marginal, and more punitive, when they were more easily understood as threats to social stability. In this second part, it discusses post-war developments in services for non-indigenous children, and indigenous child welfare services. It concludes with a discussion of the historiography of child welfare in Australia arguing that because, to date, historical writing has concentrated on localised or specialist studies, child welfare professionals have limited access to an understanding of the history of the systems within which they work.
