The two previous posts make good points. I served Eight years in the Australian Army and passed Pilot selection. One thing that was made very clear during RMC selection and training was that we would be Army Officers first and foremost and Pilots a very distant second (I was DE SSO). I spent about half of my time with RAAF units so I know they tend to hold Pilots in much higher regard.
The ROSO for ADFA Pilot is about eleven years from memory, so if you don't like it you have a long time to think about it. Flying fast jets would be amazing, but they only train maybe 10 F-111/18 Pilots a year so chances are slim. There are also moral reasons that may sway your opinion, as stated in above post.
If you just want to fly there are lots of other jobs out there. Assuming you have passed selection for all above, my pick would be QF.
