I have no problem with Australians, I think they're mostly great. Occasionally you'll get an obnoxious one who insists on inserting "gaol" into a conversation just to kick off an insanely stupid side thread.
I mean when two Australasians speak with each other in a foreign place I definitely hear the accent rise up a bit more outta the both of us but Aussies are something else when it comes to putting on a show, especially when Americans are involved (in my experience).
