After reading this thread, I can't help but link this to previously discussed topics.
As mentioned by an earlier post, are the holes in the swiss cheese becomming more aligned?
* Jetstar boss AJ reported as stating, if pilots aren't getting burnt out within 5/6 years, their not working hard enough.
* The letter to Jetstar crew some time ago from senior experienced pilots, highlighting the need to lift there standards. Then management publically criticising the authors of the letter.
* The reluctance of J* managament to allow line flight operations audits by outside parties. Whether that be QF audit or the University of Texas.
