OOL ground staff are aerocare contractors so would know no more then anyone else here.
I am VA crew, as much as most of us wish a BNE base would occur it's now more unlikely then ever - from Feb BNE departures go to only 3 per week and even in March 2012 when they pick up to 6 a week - that's only 1 more then now. To make the base viable they need more then that.
The only other thing to add is that a significent amount of VA crew (including almost all the FM's and a large number of CL's) reside in SEQ - if/when a base is announced they would no doubt be able to fill it internally and still have a very large transfer list to action.
If you want to fly for VA don't let the SYD base put you off - depending who you believe in management between 30% & 50% of our crew commute (a majority from either SEQ or MEL) and it works for all of us. More crew seem to be moving back home to cities out of SYD and now commute all the time.
