Like many other British colonies, Australia too experienced the ill effects of racism. The British settlers wanted to establish White supremacy over the country.
Moreover, traders from Asian countries, especially China were posing a threat to the British trade. To counter it, the government came up with the white Australia Policy in 1901. The policy banned all non-white immigrants.
The White Australia policy was in the rule books till the 1960s. it was ultimately banned in 1966 and the country invited immigrants from all parts of the world. it also opened its gates to the refugees of the Vietnam war! People all over the world now move in to Australia for quality education and employment. And it has people of all races; 26 percent of its population are immigrants!
