Yes, I think you're right and both the Jetstar and Virgin cadetships are on hold. I've also heard the last batch of Jetstart cadets are still waiting for a slot and will be for a long time.
I've met maybe a dozen Jetstar cadets over the past few years and they all seemed to think they'd won the lottery.
Also know one guy who did the Sharp Airlines cadetship and is not flying RPT turbines. He was very happy with the training and outcome.
