When the White fellas first came to Australia. They bargain with the Aborigines promising in a written legal document a percentage of goods and stock grown on the land as recompense. For the white fellas inhabiting it.
What followed was a bad bit of history no white fellas want to believe or convinced themselves it happened so long ago its not their problem. Even though some of this history wasn't all that long ago and the youngest of the 'the stolen Generation' are in their 50's.
There was a push to get the original Promise of Goods and Stock to be honoured. But last I heard that was back in the early 2000's and fuck all came of it.
