Early/late or mid september? And where are you heading out from? I'd like to but i am from victoria so just the trip up could take more than a week to do it properly (eg check out birdsville and corner country on the way up)
I've recently been to camp coffs with a bunch of other jeepers and found out that the 2012 Australian jeep jamboree will be held in the last weekend in september around sydney in the blue mountains so i'm out of contention for that cape trip of yours mate. Have a good one though.
