I don't think the great jobs abroad will still be there for J* Cadets in a decade.
They will compete with thousands of other underpaid, in-debt pilots (like Indians ) for jobs that are a shade of their former COS's.
Why?
Because airlines will recognize their predicament and their pliability due debt and career hopes. And adjust conditions accordingly. J* cadets will leave the Australian lifestyle in the hope of a quick command abroad and the monetary advantage of not paying as much tax.
The haves and have nots amongst pilots will be more obvious. And they will be bitterly envious with nobody to blame but themselves!
Rant over and in summary. Pilot shortage or not, the high paying jobs won't be abroad and it's your own fault. The airlines know your price.
