I usually don't need to know what VFR requirements are when I fly Australian registered a/c as IFR in other countries.
But yeah, good call, so I'll amend my assumption to say if you're a VFR pilot, then go to the VFR flight guide as it filters out the excess IFR stuff that weighs you down in the AIP.
Just remember much of Australia does not have the radar coverage of the US, so if you're flying VFR, make use of Sartimes with your flightplans (which are pretty much ICAO standard format) and if you have an iPad, OzRunways is my suggestion for your mapping and planning.
Lots of big open spaces, so carry plenty of water and remember the sheep are about the only thing that aren't poisonous.
Also strongly recommend you get an ASIC card application in at least 6-12 weeks before arrival, as they can take forever to approve and it will make access slightly better than impossible at larger airports.
