Aussie tracks boring!!??? That track is awesome, can't fathom why it isn't in the game. Having watched Bathurst 1000 this year I really started to appreciate aussie car culture. A combination of a twisty bumpy track with lots of elevation changes and huge speeds (300km/h!) with great sounding v8s going round it. It's like a combination of BTCC and NASCAR, the best of both worlds.
The race this year had a cracking finish too

Action like this could be taking place in GT online lobbies:
Seriously PD, step up!
