The reason why some pilots have gone overseas is because of the lack of jobs in Australia. Where operators such as the RFDS require such inflated high experience before considering an applicant, then no wonder they have trouble trying to attract someone to live in the outback. Why fly a Kingair or PC12 in the bush competing with millions of flies for your steak and eggs when you can go overseas and fly to exotic destinations and stay at top class hotels on a better salary and this is available with less flying experience than it takes to qualify for the RFDS.
There is a great world of flying outside of Australia where the pinnacle ambition of so many young pilots is restricted to flying ICUS in a Navajo from Thingalongjaba to Bullemakanka until a command on a C210 at Marble Bar comes up.
