I know a lot of MAM crew are hoping for permanent work with Qantas but have you considered jetstar International?
On their website they are taking applications for
direct entry CSM's for their 'widebody operations'.
I would think that any MAM crew would have a great advantage with all your experience on QF's A330's, as they are the aircraft Jetstar will start with!
Fortunatly I now have a full-time job with QF but if I were casual I would jump at the chance of a direct entry longhaul CSM job
