Agree with cam on red here. Jetstar is not competitive for most looking to leave. The money is less and lifestyle is no more stable than defence.
VB is marginally competitive on pay but only on the 737, the lifestyle also won't suit everyone. Tiger doesn't seem to be any better. That leaves Qantas and Cathay DEFO as the promised land and neither look like recruiting anytime soon. My bet is a slow trickle of those not satisfied with their individual circumstances.
