I think, I might be wrong, that some Indigenous people prefer to be called (as a group) by their local tribe name if you know it. Such as the Koori's and the Noongars (sp?) ... but unfortunately i often forget and get confused. I wish that each state would have signage near the roads (like those brown historical ones) saying "you are now entering Koori traditional lands"... like "you are now entering the state of Victoria". I think that would of great educational benefit to us all and display a lot of respect.
