Cadetships continue to be oversubscribed at Jetstar, QantasLink and Rex et al.
We would take a slightly different position.
Australia is no different to Europe, demographics are at play.
Network cannot crew their flights with the remuneration offered.
Jetconnect cannot either.
Further, having personal insights to at least one of the cadet programs to which you refer, they are most certainly not 'over subscribed'
Were they to be 'full' the rate of CPL issuance is simply not sufficient to alleviate the retirement rate. Simple mathematics. The airline management although slow to realise are awakening to the stark reality: their crewing formula is unsustainable at current remuneration, hence JQ crewing the flights and 457 announcement over Christmas.
