Rumours are rife that a SYD base will be up and running mid year. Some of the SYD people have already been told unofficially that this is happening for the 737.
Would make it easy to then put EMB into CBR, CFS and BNK from SYD.
As we are only starting with 3 planes I cant imagine that you would need many flight crew. Cabin crew will be crossed trained I am lead to believe.
