G'day Dogma,
If you aren't used to remote area navigating, I would definitely think about a GPS. Depending on when you are going to be travelling out that way I would also consider flying in the morning to avoid the worst of the thermals and thunderies if you are going to fly in Summer. Another good tip is to take and drink plenty of water.
Also, take a camera, you are bound to have a lot of fun!!
