Sydney tech crew base opened 1st april if I recall correctly. Not a huge takeup on it, although word has it that a lot of the commands from BNE that were going to be sent to MEL are now possibly going to be sent to SYD instead.
Rumour abounded a while back re a full size syd Cabin Crew base too (as opposed to the original syd cc base that was wound down), I wouldnt think its terribly far off either.
