Are Australian boys British boys?

Australia's population is mainly white, and more than 90% of them are immigrants from England and Ireland.

English is the mother tongue.

The official language of Australia is only English.

Whether it is an English boy is uncertain. For many reasons, people with Australian nationality are not necessarily born in Australia, and even if they are born in Australia, they are not necessarily white descendants. Even Australian-born Chinese descendants who still speak Chinese at home are not British boys.

This is the same in America and Britain.
