This caught me out last year, as someone who held two ATPL's before getting my CASA one I thought that someone was just taking the piss when I was informed you had to maintain night currency on top of everything else. We had a couple of Captains last year who had to be flown to Melbourne for 20 minutes in the simulator just to do a night take off and landing at the end of summer?? WTF
Best way I can describe RPT operations in Australia is that it is like your local flying club with A320's instead of 152's. There does not seem to be a dividing line between recreational flying and professional flying.
