The money goes to OAA and I can't see how how Jetstar are trying to take advantage of anyone..
Have you ever looked at the eba's of every airline in Australia and compared a jetstar a320 junior first officer salary to the salary of pilots at every every other airline that fly jet aircraft? It is absolutely peanuts for a pilot of a jet aircraft.
If jetsar paid its cadet pilots on a level 1 first officer salary and after 12 months they could be promoted to a level 2 fo (like what happens to direct entry pilots), it would be reasonable, but sticking it out on a junior first officer salary for a couple of years before being promoted to a level 1 first officer salary is just screwing over cadet pilots big time.
