Also try Kidmans from SA. They have stations in SA, QLD and WA and operate Super Cubs, a C206 and possibly a C172 which they only acquired recently.....I think? They require around about 300hrs and prefer pilots with a rural background but they do take "city types". No experience necessay as they put potential pilots through a low level course and tail wheel endorsement with John Freeman and then further mustering training with the Chief Pilot.
They advertised for a driver a couple of weeks ago so do a search through the OZ JOBS forums for further details or check out their web site
