Not suggesting they will be on the Jetstar EBA, just saying the company wide culture has changed so that people are now bonded instead of paying upfront for type ratings. Word on the street is that the Turbo prop pilots will be employed by Jetstar NZ and that NZALPA have been approached for a variation to the current CEA to include a turboprop scale.
So as a job this might not be too bad, you may find a route to the A320 after a bit of time on the turboprops. I have no doubt there will be plenty of applicants for the FO positions, they may struggle for the CP spots though.
