At least if you go QF and you don't like it, you can leave. This is not so in the ADF. If you wanted to stay QF could offer you a fairly secure career with exellent T&C.
In terms of the moral problems I am not averse to the ones mentioned.
Neither was I until my first operational o/s deployment.
Its your life, just think hard before going down that road. There is a good reason why they have a ROSO for all service personell, and it has nothing to do with the cost of training.
Remember, ADF pilots cse has a very high fail rate (you can be failed for officer qualities etc.). If you do fail, you will spend your ROSO as an officer flying a desk, not aircraft.
