G'day mate,
I was/am much the same as you. Wanted to become an Air Force pilot for ages. Still an option. Anyway, From your position, the next step is to apply for ADFA where they will pay for you to study a university degree while training you to become an Air Force Pilot. Now to the bloke who said its very selective because you're flying planes which cost a lot to maintain and buy, think you're being a little naive, he is right that there is a fair bit of work you have to do for you to achieve your goal, but whether you become an Air Force Pilot or not is completely down to how motivated you are. The Government is very happy to aid with this motivation by offering $40'000 every year you study, in the exchange for the amount of years you study for + 1 more, so if you study at uni for 4 years, you have a compulsory service of 5 years.
Hope this Helps!!
I don't mean to be a dick, but a few points:
-Australia only has 40-50 fighter jets, and there are probably hundreds and thousands of other applicants each year applying for those few spots to become a fighter pilot. Even if you do get in the RAAF, you're going to go through extensive medical and pilot tests to qualify you as a jet fighter pilot before you actually fly a fighter jet plane. You may even be deemed unsuitable due to a small medical issue--my year advisor at high school was refused during the application stage because he broke his forearm or something when he was little. Apparently, this means he could not handle the G-forces when flying the F111 or F18.
-The turnover rate is quite high. It costs $50 000 an hour just to pay for the fuel of an F18 Super hornet to keep it up in the air, so you're only going to fly around 4 hours each week, so some pilots leave the RAAF to join the commercial airline pilot industry once their ROSO is finished instead of staying on.
-the ROSO is actually around 14 years if get accepted as a jet pilot, I think, not 5. 5 years is only for those roles which have a high turnover rate and don't cost a lot in terms of training, such as in Transport or in Logistics.
-I do agree, however, that ADFA would be the best pathway to take if you wish to become a fighter pilot. Apply for it in year 11, and if you do get accepted, study aeronautical engineering, and you should then become a very competitive candidate for fighter jet pilot training.
Now, I'm not saying you should give up, don't. Take that risk and go for it, you never know, you might actually get it. All I'm saying is that you're going to have to work really hard now on to try to become a jet fighter pilot. Do things to make you stand out. Get excellent marks at school, do sport, volunteer, undertake pilot training if possible (I assure you, there will be other motivated candidates who have plenty of flying hours experience competing with you), learn as much as you can about the RAAF, and try not to get yourself physically or mentally hurt.
