My two bobs worth: Crewing wise, the biggest movers in the foreseeable future will be the ATR regional, and demand for Domestic drivers for an expanded TT OZ.
Assuming that there is no contraction of Virgin's operations. If Tiger replaces Virgin in some ports there won't be much gain unless Virgin expand either overseas or interstate. I can't see them expanding Tiger, whilst shrinking Virgin and leaving guys sitting around like QF does.
If Virgin and Tiger expand then the regionals are going to really start hurting and you might even find guys punching out of Jetstar. If that happens it might be the old pilot shortage again.......
