.Virgin and in the past Qantas have also offered "cadetships". Very similar to the Jetstar Cadetship.
Virgin pays for your training, they pay you while you train, they pay for your accommodation.
Qantas cadetship you eventually become a second officer and earn the same income as the direct entry pilots (the way the jetstar cadetship should be). Sure, you have to pay for the cadetship like the jetstar cadetship, but at least qantas pay cadets at the same rates as direct entry pilots.
Jetstar does neither, you pay for your training, and start off on a junior first officer salary which is $30k less than a level 1 direct entry first officer (and that's before paying off the huge $150k+ training debt). It's not fair on the cadets at all.
