Purpose: This paper draws on the archival records of the Victorian Education Department, literature produced by the governing authority of Tally Ho (the Central Mission), and newspaper reports produced in the mid-20th century about school and education at Tally Ho. This paper also draws on material from the Victorian Aborigines Welfare Board and the Northern Territory Department of Welfare, as well as two historical key government inquiries into the institutionalisation of children. Design/methodology/approach: This paper uses Tally Ho Boys' Training Farm as a case study to examine the intersection of welfare systems, justice systems and schooling and education for Aboriginal children in institutions like Tally Ho in the mid-20th century. Further, it provides perspectives on how institutions such as Tally Ho were utilised by governments in Victoria and the Northern Territory to pursue different agendas -- sometimes educational -- particular to Aboriginal children. This paper also explores how histories can be reconstructed when archives are missing or silent about histories of Aboriginal childhood. Findings: This paper demonstrates how governments used Tally Ho to control and govern the lives of Aboriginal children. By drawing together archives from a range of bodies and authorities who controlled legislation and policies, this paper contributes new understandings about the role of institutions in Victoria to the assimilation policies of Victoria and the Northern Territory in the mid-20th century. Originality/value: Scholarship on the institutionalisation of children in the post-war era in Victoria, including the ways that schooling and justice systems were experienced by children living in care, has failed to fully engage with the experiences of Aboriginal children. Historians have given limited attention to the experiences of Aboriginal children living in institutions off Aboriginal reserves in Victoria. There has been limited historical scholarship examining the experiences of Aboriginal and Torres Strait Islander children at Tally Ho. This paper broadens our understandings about how Aboriginal children encountered institutionalisation in Victoria.
