The other thing too is not all Aeromed flying with RFDS is ALL Med 1 work in the middle of the night in crap weather. A lot of the work they do out of places like Mt Isa, Charleville and Cairns are clinics - in the day and of course mostly in perfect weather. A lot of this work used to be done in clapped out PA31s and the like.
RFDS QLD has C208s - they aren't using them for Med 1s in the middle of the night, but clinics and other non urgent work - as is the PC12 in CNS and mostly the ISA based a/c, this now keeps all the clinic work in-house and they don't have to farm it out to GA operators.
Again you want the arguement of if a Dr is safer in a brand new C208 or a PA31 with 16,000 + hours operated by perhaps a dodgy GA operator ?
RFDS does fantastic work - I think their choice of a/c provides a very safe platform for the wide variety of work that they do, money sadly is not unlimited - and some of the locations served are not 1500m bitumen strips either !
