There are currently no provisions to transfer between Qantas Domestic Pty Ltd and Qantas Cabin Crew Australia Pty Ltd. They are 2 totally different cabin crew labour-provision companies serving different purposes. The EBA for QD has not been established yet, and I doubt very very much that there will be provision to transfer to QCCA. QD is a bare bones operation and it would cost too much to administer any transfer mechanism to another subsidiary of Qantas. There is also no provision under Part II of EBA8 (which covers QCCA) to allow for transfers.
To answer your second question....it all depends on what you want to do...if you want to fly around the world, then apply to QCCA. If you want to fly around Australia, then apply to QD. Don't apply to QD hoping that you may get a transfer to QCCA because at this stage, there is no mechanism for this.
