As a MAMer it will be very difficult to say how many trips etc you will get.
I know in the SYD base alot of them are just doing MEL returns this month - if your a language speaker and you hold an aussie passport then you will prob do some regionals.
Really hard to say as you dont get to bid for any trips - you just get what the allocate you.
A good idea would be to start sleeping with someone in crewing.
