nomorecatering,
I drove from Sydney to Alice the end of November, in my 4 cyl 1.3ltr manual.
We went, Syd to Armidale (visited friends) Armidale, back to Tamworth, across to Wilcannia, then Wilcannia through Broken Hill, down to Peterborough, then up to Coober Pedy, then Coober Pedy to Alice.
Make sure you have lots of water, you shouldn't need to take extra fuel as there are reasonably spaced Service Stations along this route, but if you are going by yourself, make sure you have a UHF or CB radio, just in case.
Oh, don't forget to have lots of CDs handy as the radio coverage isn't too good.
Enjoy the drive!
