Neville’s and Cook’s solution to the half-caste problem was biological absorption, colloquially called ‘breeding out the colour’. This entailed directing persons of mixed descent into marital unions with white people, so that after several generations of interbreeding all outward signs of Aboriginal ancestry would disappear. It held an incongruent array of aims and means. Absorption promised to resolve the supposed problems resulting from racial intermixture by encouraging still more intermixing. It aimed to uphold the ideal of white Australia but flew in the face of popular notions of white Australia as a doctrine of racial purity. While racist in many ways, absorption simultaneously defied prevalent racist assumptions of hybrid inferiority. It parallelled eugenicism in certain respects, but also clashed with eugenic principles. It was inspired partly by humanitarian welfarism, but evinced profound disdain for the subjects of its welfare interventions.
