Hi TOGA...I usually read pprune but don't post very often. Not sure where they are conducting the interviews in Syd, but it seems that the Sydney based positions are only for shorthaul and they will all be casual (although this could always change) The Perth based positions are longhaul and probably either permanent or maybe fixed term contracts.
Anyway advertising in Syd should start any time, so ring the hotline number every day because they probably won't keep the lines open for very long.
Good luck !!!!!
