Hi Ice Tongs
Impulse/QantasLink have just hired their current training school based ex SYD.
Eastern/QantasLink are always on the lookout for new blood - check them out on
www.cabincrew.staffcv.com - you can apply on line to them and others (free for the first airline, it will cost you for others though!!!)
QF are expected to recruit this November for more contract and casual positions ex SYD (and other ports too I believe - may be wrong!)
And I think Hazelton and Kendell are looking for crew too (though not always guaranteed a SYD base with these ones)...Eastern only base their crew in SYD, so they're always a good shot if SYD is all you want to fly from (pay isn't the best, but the benefits therein, like progression to short haul etc pay off in the long run).
Good luck!!! Let us know how you go!
