Plenty of bars will show it or you can ask to have it turned on.
If you want to watch in the company of fellow aussies your best bets would be:
- Score sports bar. This is the biggest sportsbar in PP and most likely the biggest screen and lots of aussies
- Gym bar. A very small pub with a loyal aussie clientele
- Aussie XL. Pub/restaurant and not a real sports bar but I'm sure there will be some aussies watching
