Race is a complicated thing.
When I saw a photo of Ken Wyatt, I thought: He doesn't "look" like an aborigine. Wikipedia says his ancestors are aborigine, European, and Indian. Are there many mixed race aborigines in Australia? Do many "pass" as whites?
This is an issue in the United States, where Senator Elizabeth Warren, who may be 1/32 Native American, was mocked by Trump and others for claiming Indian heritage.
