Thanks for the info. I'm not Australian but it appears my take on the whole situation is right. Isn't it a shame that Canada can diverge so much from Australian and US politics? When both their main centre-left and centre-right party lie quite a lot to the left than the Australian counterpart.
I really can't imagine the Australian Democrats or Greens form outright majorities in state parliaments and govern on its own - not even in Tasmania. But this has precisely happened at some point or another in many Canadian provinces - Saskatchewan, British Columbia, Manitoba, and (horrors!) Ontario. Sometimes I just shake my head when I look at Canadian politics. (though our own on this side of the Tasman isn't much better) Thank God that we have Australia when the other two members of Old Commonwealth countries (NZ and Canada) have largely gone mad.
Correct, there is absolutely no chance of this happening in the foreseeable future. The vast majority of Australians, despite the cr@p we see in the media, are really deeply conservative people.
