The assimilation policy was a policy of absorbing Aboriginal people into white society through the process of removing children from their families. The ultimate intent of this policy was the destruction of Aboriginal society.
The Aborigines Protection Board officially adopted this policy in 1951. From this time the Board substantially increased the already established practice of removing Aboriginal children with fair skin, referred to at the time as 'half-caste' or 'part Aboriginal', from their families. Children were placed in institutions where they could be 'trained' to take their place in white society.
