FFF,
RFDS is an Australian outfit known as the Royal Flying Doctor Service. They have bases all over the country and they fly Kingairs, PC12's and I believe there are some Conquests around too. They are very well paid and the overall package isn't bad, esp when you consider it's a GA job. It isn't as well paid as the jet jobs but compares favourably with the turboprop jobs.
From memory, a mate in Mt Isa was earning +$A55,000 plus car and rental assistance (and superannuation, discounted airline tickets etc)(Checkboard's sister is a Doctor with RFDS, she earns +$A100,000, free car, free house and bills paid for)
To get a look in you need several IR renewals, 3000 hours TT, a min of 500 hours in command of multiengine aircraft and from 200 to 500 hours of night flying. (Depends on the region). Turbine time, esp on kingairs is desirable as well as remote area experience. A season or two in the Kimberley or the Territory is ideal.
It tends to be a dead man's shoes sort of job because not many people leave the RFDS to go to airlines. They do prefer to hire older folks though. (Although the Derby base seems to have a high turnover)
