Mate in the past they have taken people from all walks of aviation life... Get your application in and get your hat in the ring now!! Update every month and show them you're keen!!
Presently they have around 40 guys on a hold file ready for when they recommence training. I think a couple of years ago when airline recruitment was going bananas the type of experience was not so much a factor. Now that things have slowed down some what, they can afford to be more picky and it seems as though that their preference is to take guys with some real multi crew time, a la regionals.
But mate you never know you luck in the big smoke, if you don't apply you don't have a shot.
Good luck
