If you are driving up through QLD to get to the top end, please let me suggest you fill some jerry cans in Mt Isa, as last fuel in Camooweal will force you to sell your ass to pay the bill! ($2.50/litre when I was there 2 months ago)
Congrats mate, i'm 5 hrs off finishing too. Might see you up there!
Happy Landings - live the dream.
