I complained on PPRuNe a few times about the lottery that is airline hiring in Australia.
Why then am I surprised that a person with 3000+ hours including King Air PIC and biz jet FO time can't land a jet job in Oz
Getting any job, anywhere, is a lottery. There are winners, and there are losers, that's how the world works. Locally there seems a reasonably steady stream of GA turbo prop folk being accepted by the airlines for jets.
