That's thoughtful but the fact is First Nations Australians in

constitute a (for all intents&purposes)tiny %age of supporters/participants of the game in this country - and furthermore their sporting-loyalties lie nigh-inextricably w/AFL, NRL etc.
Of course we all know there've been notable figures of Indigenous heritage involved in the game here(Charlie Perkins, John Moriarty etc.), but the fact remains that kids of that background dream of becoming the next Nicky Winmar or Johnathon Thurston - not the next David Williams or Travis Dodd, let alone a First Nations equivalent of Irankunda or Jordy Bos.
