Yea, why STAA? You want to go to Ballarat and sit around watching china southern, qatar, tiger cadets being rushed through flying phase and the private candidates getting 1 sortie every 2-3 weeks?
After that coming back to sg, having your CAAS CPL dragged because they are not to keen issuing you a CPL without an employer, and your only chance of finding work is probably with one of the simulator outfits.
Heed my advice, don't go the private route.
