Mate, the guys are right...there won't be much avaliable in aviation just yet on account of your age. Most of us here (including myself) have done time at McD's or Coles and poured beers in various pubs and bars, it's a short term pain for that coin to get airborne.
Go with Bidgee's suggestion, and go to you local Coles etc. When you hit 18, go with Apache's advice and get your RSA cert, that will come in useful whilst you're moving around in GA.
Having just said that...
does anyone know if one of the regional operators would take this kid on as a baggage handler whilst under 18?
Good luck with your flying, post on this thread when you've gone solo and let us all know how it went
