Why are the local residents of Australia not yellow or black, but white?

Australian Aboriginals are dark-skinned and mostly live in the tropics, that is, northern Australia.

The reason Australia is now a white world is because, in the 19th century, Australia was discovered by Captain Hook and later became a British penal colony. Britain was in chaos at the time, and even minor crimes of theft were required to be imprisoned. As a result, the prisons were overcrowded, so it was decided to put some of the prisoners in this large prison in Australia.

Later Italians began to immigrate to Australia, and later the gold rush also attracted a large number of Chinese. So Australia truly became a country, and it was mainly white people.

When the whites landed, they killed a large number of indigenous people.
