When the Jetstar F/O vacancies were advertised by FSO I recall thinking the command experience requirements were well in excess of what any cadet would have unless they did quite a lot of private flying.
Correct, there were current QF A330 F/O's who didn't meet the requirements for a J* F/O.
There were current QF Captains who didn't meet the requirements for J* Captain, despite having a command at QF for a decade or so. Even many A330 QF check and training Captains did not meet the requirements.
The requirements were a complete joke and designed to ensure no QF (well except maybe ex AN 320) would meet them.
