The word on the street is that
VB and Jet* will be looking for another 100-150 pilots each over the next year.
After that there will likely be little movement on the domestic scene for a few years, especially if someone fails in what is an overly competitive market with rising oil prices and stimulus still propping up the economy. If someone like Tiger pulls out there will be even less hiring as the excess of pilots are soaked up.
So the RAAF should see an increased attrition rate this year, but it will only likely be back to normal levels, before everything bungs up again (so if you are thinking of leaving The Firm, nows your chance!)
