Stevie boy - one thing you might consider is doing a degree course. It wont make any difference to getting a GA job, but it definitely puts you closer to the top of the resume pile with Qantas. Maths and Physics to a year 12 level are essential, but its not impossible to get in without year 12 english. Once thats done - its a lot of hard knocks and kicks in the ghoulies. Worth every bit of it.
