I live in Australia and I'm not too worried if I have to wait until tomorrow (October 2nd) to play GTA Online. It doesn't really bother me too much. Gives me more time to get myself familiar with the map (as if I'm not already familiar enough). Plus, it means I can get even more hyped up!
But to those saying that Australians have to wait "the same amount of time" for GTA Online: we don't really, because we got GTA V before almost everyone else, and we had to wait the longest between 00:00 September 17th to whatever time GTA Online comes out on October 2nd. Not that it bothers me, I just thought I'd point it out.
