Happy Bandit,
I'm no longer in Oz so I'm a bit out of the loop, but you mentioned that there are not enough eligible SO's to transfer to domestic fleet.
Eligible?
I would imagine that the vast majority of SO's who joined in the past few years came from multi crew turbo prop operations and would most certainly be eligible fro domestic fleet and the ones from GA pistons would have certainly served enough time as an SO to be able to move across to domestic.
Or do you mean "eligible" in terms of type freeze, bonding to aircraft type etc etc?
Eternity.
