Wow, certainly heading out west on that trip.

It looks like most of the rental companies operate out of Kal, I would book early and ask for a second spare wheel to take.
Might also be a good idea to hire a satellite phone (as I highly doubt there will be cell coverage on the gold fields).
Are you staying in accommodation in town each night, or swagging it out bush?
I have a couple of mates who live in Kal and go prospecting.
