Hey i went for RAAF Nav last yr and was unsuccessful, got into the final 20 and they picked 7 based on highest UAI (i got 92.15).
You have to go to selection board and pass medical/physical/psych which is easy if you are fit healthy and you have always wanted a career in the forces. Um... if you want a popular job (any RAAF or RAN pilot) you really have to get a UAI higher than 95 and pass the tests. You have to apply before july and your tests will be in august/september/october. Which job are you applying for? Also you have to be confident and display good team communication. I have heaps of tips for passing RAAF selection board (the last step before UAI) when u get to it, email
