I'd stay far far away from RFDS WA. Have heard nothing but trouble with the way the management operates. I personally know of 2 very experienced and all round great pilots who have left in the somewhat recent past because of management. 1 left within a matter of weeks and the other left after complete burnout from the way they were treated. Those are just the 2 that I know personally but I've heard theres many more, just havent heard first hand from the others. RFDS WA is rotten from the top down.
Sounds like RFDS in other states are ran decently enough.
