A TD60 would be great however the juice it will consume and the two bucks plus you'll pay per litre ain't worth it. Get a cheap four banger with aircon and you will be leagues ahead.
You won't be driving the tanami or the Gibb looking for work and when roads close due flooding they won't reopen till your average sedan can cross it. Pick a spot dig in for the wet pour beer and wait for a slot at the glimpse of the dry.
