There's some obsession that you need an ATPL as soon as you meet the requirements. Why?
It was explained in another Pprune exchange, Morno which you may have participated in too. It is NOT an obsession it is a fact of life under Part 61. And that is it seems Jetstar recruiting policy requires an applicant to actually have the bloody ATPL in their greasy hand before an interview is considered. I know a bloke that contacted Jetstar HR people a few days ago and was told that was the policy - like it or lump it.
It matters not how many hours you have flown in command overseas or in Australia, you won't get a look in without the full Australian ATPL and not just the subjects. Same if you are applying for many overseas jobs. I understand there are other operators in Australia that require a similar qualification; meaning no ATPL - no interview. The problem is the vast oversupply of commercial pilots in Australia so the operators can pick and choose and cull the CPL's. .
