nomorecatering do not worry about the drive just take water, tapes/CDs and enjoy the drive. I still remember driving out of Melbourne for Darwin in March 1994 going across the Westgate Bridge and the song "Things can only get better" came on the radio. Have not looked back.
For the drive I stopped every hour from start to finish and took a photo of the road in frount of me. it is an interesting 50 odd photo's.
Enjoy your territtory time.
