I remember reading a book about a man living in Australia, who had a Japanese father and an English mother. He had another friend in the same situation, and he was caught in England during the war. The author of the book was caught in Japan at the same time.

I, myself, am mixed race, even though it's not obvious from looking at me (my great-great-grandfather was West Indian).

I also remember a discussion where a man on Facebook said that he was an eighth Australian Aboriginal and someone else jumped all over him and said that it was racist and that either he was Aboriginal or he wasn't. I can understand the second person's statement, as in a shameful time in Australian history, they were taken by how white they appeared and how, after Indonesia was granted independence from the Dutch, Australia wouldn't accept any Dutch-Indonesians unless they were at least 75% European, but how a person identifies is up to them. The man who said he was an eighth Aboriginal, in my eyes, said, "Yeah, one of my great-grandparents was Aboriginal."

Where I think we get into murky waters, though, is some Australians who say, had an Aboriginal great-grandparent, and all the others were European, may identify as Aboriginal is that, as was outlined in The Chant Of Jimmy Blacksmith, many Australian Aboriginals were, as part of a eugenics program, encouraged or coerced into marrying Europeans. Some people, who say had one Aboriginal parent were treated this way, to try to reduce the physical and genetic amount of Aboriginality, and they've learnt about it and thought, "Hey, this was terrible."
