Exmax,
given the recent QF transfers from shorthaul to longhaul it would seem that QF domestic has surplus numbers.
Your best bet would be to visit the Jetstar or Australian Airlines websites.
I've no details about
VB but it seems they are recruiting all the time.
Good luck with your search.
Maybe a seperate thread asking the same question may deliver more concrete info from others," more in the know".
Cheers
