Interestingly, in W.A. Up until 2013, if an aboriginal person who was more than one quarter aboriginal died intestate, then his estate had to be handled by the Public Trustee.
I didn't know this and when my aboriginal husband died in 1991 I was amazed to receive a letter from the Aboriginal Legal Service informing me of the fact. Not that it was a problem, he didn't have any estate to disperse and from my dealings with the Public Trustee, they appeared very impartial in their decisions.
What I did gain from all this was a pile of old Native Welfare papers giving us access to unknown family history. These papers were what the Public Trustee used to decide that my husband was in fact more than one quarter aboriginal. The whole family were grateful to receive this history.
This law changed in 2013 to bring it in line with non indigenous inheritance laws.

Dear Joe,

I agree that a Member of Parliament should have
stayed out of this matter. It was not a wise move
to get involved.

FMD...This is another "I'm my own Grandpa" story....goes right over my simple head...
