Griffith have a history of claiming the inside running into various organisations.. Cathay Pacific was a big spin some time ago now the RAAF etc.
Both organisation have their standards of entry and if you don't cut the mustard you won't be accepted whether you come from Griffith or anywhere.
Most GU students will struggle to: a) pass the CPL flying b) get an aviation flying job c) realise their ill conceived dreams of flying for an airline.
Griffith are big on spin and once the yearly census date has passed they get the $$$ from the Feds via Fee Help (HECS) and don't particularly care if you don't finish as they will not have to pay out the aviation training provider for wasted flying training.
If you want an airline job, just do the CPL straight up and then go get a job. Most people who follow this route have the motivation to succeed, something frequently lacking in uni based program cadets.
