After World War II the Australian government wanted to attract migrants. The Ben Chifley Labor Government started the Snowy Mountains Scheme which needed a large population of labourers. Australians worried less about taking people from different cultures. Through the 1950s, many Southern and Eastern European refugees resettled in Australia, leaving a Europe still recovering from World War II or the Communist Eastern-Block behind. Liberal Prime Minister Robert Menzies' Government brought in the Colombo Plan which brought Asian students to Australian universities to help Asian development. In 1958, Menzies ended the "dictation test" and the Government said well qualified non-Europeans would be suitable. Other laws made it easier to bring non-Europeans to Australia. Prime Minister Harold Holt's "Migration Act, 1966" effectively ended the White Australian Policy so that migrants from different parts of the world could come to Australia, like refugees from the Vietnam War. Finally in 1973, the Gough Whitlam Labor Government made a law that Australian immigration officers should "totally disregard race" when considering migrants. But Whitlam took in less migrants in total, and the number of migrants from outside Europe did not increase until the Malcolm Fraser Liberal Government (1975-1983).
