Cobham will crew them, they are the jet operator for Qantas and have been for a long time. They are separate form QF so there are no MOUs required and no none can demand slots as they are not owned by QF , it is the future , outsourcing . The group has become to expensive.
Cobham are cheap and offer a complete service, cabin crew, operations engineering, training etc etc all in house, QF just fil the seats and pay the charge , leave the dramas to the Cobham management.
Looking at some of the posts probably for the best.
