I had asked a question on pprune about the Royal Flying Doctor Service, as I'm wanting to go down towards that path. They like King Air/ turbine time, with about 3,000 hrs TT. The RFDS will sponsor for a permanent visa at the end of the 1 year temporary visa (also the probationary year). Not sure on what's required as far as conversion of licenses or to establish permanent residency. This is the info that was PM to me on there. They have no radar vectoring for approaches in the outback, NDBs are still being used, and it's mostly solo PIC night flying.
