A shortage of Aussie pilots waiting for Jetstar jobs and their 'crap' wages? I wouldn't call $160 for a starting skipper crap personally, but I would call $65K, as in the former Skybus, or $17500, which is the starting at some US regionals.
I think it's quite good that they are hiring experienced skippers to fill seats instead of pushing through under qualified Aussies and endangering lives. I have no doubt that when the locals are up to snuff, the foreign contract pilots will be sent down the road. Frankly, that's the shame, but it's the way it is.
Now as far as the V Oz wages go, so far that has been a shame; but then again they are not getting many takers either.
