Hi,
As a former RAAF instructor, my advice is say/do whatever is necessary to get accepted into the program because what you finally get has nothing to do with what you desire. That is determined by others at the end of your training when they know how good you are. At the end of each course the powers the be determine what vacancies exist in the system and the senior officers at FTS fill the slots according to skill/psychological/and other factors of each graduating student.
However considering the the available course stots and the number of applications all I can say is - GOOD LUCK.
Have a nice day
