If he wants to reduce duplication across the Tasman, start by rolling Jetconnect into Qantas mainline (while protecting the jobs of the JC crew).
How would you manage that one? Unless you're referring to providing SO positions. I don't think you'd find many current SO's or FO's who would agree to them keeping their current rank and fleet if the aircraft were moved back to Australia. I would assume the crew would be subject to the same recruitment process that other group pilots are currently undertaking.
