Single flasher, have a mate who is Aussie flying abroad, 15,000 hrs, flown 3 narrow bodies as Captain ( over 7000hrs ), 3 years on 320 but not as captain.
Tiger told him they can only take DECs that are current as captain on 320, he later found out they just hired a guy as DEC who has not flown for 4 years...jobs for the boys.
BTW, are you Aussie living in UK ? I don't think pilots are on the immigration list if you're not.
Good luck.
