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.
Spaking of the name Australian Liberal Party, not only Americans, but I imagine Canadians will also have some beef with that name as well. I read an account of a Communist Broadcasting Corp reporter on staff exchange with the Australian Broadcasting Corp blasted that the Australian Liberal Party, unlike its namesake in Canada, is "liberal in name only".
