White Australia Policy,the anti-Asian immigration policy initiated by the new Commonwealth of Australia in 1901. It reflected a long-standing and unifying sentiment of the various Australian colonies and remained a fundamental government policy into the mid-20th century.

Each of the The Australian colonies had passed restrictive legislation as early as the 1860s. This was directed specifically at Chinese immigrants, but later a popular cry was raised against the increasingly numerous Japanese—especially after Japan’s victory over China in the 1894–95 Sino-Japanese War—and against East Indians South Asians and Kanakas (South Pacific islanders) as well. Fear of military invasion by Japan, the threat to the standard of living presented by the cheap but efficient Asian labourers, and white racism were the principal factors behind the White Australia movement. In 1901 the Immigration Restriction Act (q.v.) of Australia effectively ended all non-European immigration by providing for entrance examinations in European languages. Supplementary legislation in 1901 provided for the deportation by 1906 of the country’s Kanakas. Popular support for White Australia, always strong, was bolstered at the Paris Peace Conference in 1919 when the Australian delegation led the fight to defeat a Japanese-sponsored racial-equality amendment to the League of Nations Covenant. From about 1950 on, the policy became less stringent, first under Liberal governments and also (more markedly and remarkably) under Labor, from 1972 to 1975. By the early 21st century about two-fifths of Australian migrants were Asian.
