Visit the Tent embassy in Canberra and say your sorry. Then book a table at a local Canberra restaurant and watch to see how many politicians and media staff are there thinking up something to get attention with.
I note too, I saw so many travellers and new australians all going home from Australia Day events that I didnt wish to go to. I do think that they should have some sort of recognition ceremony for indigenous Australians. Maybe next year they could give them back the land around Manly? Umm food for thought.
