Fraser maintained some of the social reforms of the Whitlam era, while seeking increased fiscal restraint. His government included the first Aboriginal federal parliamentarian, Neville Bonner, and in 1976, Parliament passed the Aboriginal Land Rights Act 1976, which, while limited to the Northern Territory, affirmed "inalienable" freehold title to some traditional lands. Fraser established the multicultural broadcaster SBS, accepted Vietnamese refugees, opposed minority white rule in Apartheid South Africa and Rhodesia and opposed Soviet expansionism. A significant program of economic reform however was not pursued. By 1983, the Australian economy was suffering with the early 1980s recession and amidst the effects of a severe drought. Fraser had promoted "states' rights" and his government refused to use Commonwealth powers to stop the construction of the Franklin Dam in Tasmania in 1982. Liberal minister, Don Chipp split off from the party to form a new social liberal party, the Australian Democrats in 1977. Fraser won further substantial majorities at the 1977 and 1980 elections, before losing to the Bob Hawke led Australian Labor Party in the 1983 election.
