Hey Rob,
Unfortunately im in Perth and when i do go to work i fly up to Karratha, which is still 1000km from Broome. Im only in Karratha an hour and jump on a helicopter out to the rigs.
I bought a car for my boy on Gumtree recently. I talked to the guy a lot to get the feel for the whole thing. He actually drove it to my sisters house, she gave him the money and also paid his Uber fare back home.
Transfer papers are a bit of a pain. There are two copies that are different colours. Seller fills in one, and the buyer fills in the other.
Go here for all the info you need:

Good luck with it.. it looks perfect. Not sure why all the black overland GCs are around Broome and Port Headland??
Cheers,
