Check out Snowy Ranges airstrip on the way, its Australias highest. Lots of good advice above but this trip is easily possible at lower levels than most have suggested.
I was lifted out of the Wongungarra by the NSCA Iroquois in the late 1980s and deposited at Snowy Ranges after being injured while fire fighting.
They were also operating the Dornier there and came within a bee's dick of losing the empennage and a whole lot more when they attempted to take off in one direction while Ben Buckley was landing in the other (there is a bit of a hill in the middle of the strip).
It was only Ben's quick reactions, spearing off to the right, that averted a major prang.
Magnificent country but a bit of a bastard when it's cold and blowing.
