Rex already flies into BNE, SYD, MEL & think there might be a few VA staff looking for jobs, as long as they are prepared to work for less & go non-unionised.
If it's A320 there won't be to many VA pilots in the mix. Good news for the the Airbus Tiger crew though.
REX may win the battle but could lose the war. There are a few more costs involved with running jets than just pilot salaries. You could have the cheapest crews but the cost of fuel/airports/catering/enroute charges etc won't change. Also they won't be able to throw a tantrum at major airports about fees like they do in the country either. It will be interesting in how they handle that side of things. Aerobridge access is another thorny issue in Australia. I doubt they would want to be busing up to 360 people every sector
