Holt came to regard the referendum as indicative of a shift in the national mood. In the following months, he toured Aboriginal communities and consulted with indigenous leaders, including Charles Perkins and Kath Walker. Despite opposition from state governments, he created a new Office of Aboriginal Affairs within the Prime Minister's Department, as well as a new advisory body called the Council of Aboriginal Affairs (chaired by H. C. Coombs). According to Coombs and Paul Hasluck, Holt had little interest in indigenous affairs before becoming prime minister. Despite this, he brought about a fundamental shift in the way policy was handled, paving the way for the federal government to assume many of the powers and responsibilities that had previously been the preserve of the states. Indigenous academic Gary Foley has said that Holt's death was a setback for Aboriginal people, as his successors did not show the same commitment to the framework that he established.
