One of the reasons for transfer of the RW was the nature of the tasking orders and the potential for the Air Component Commander to be out of touch with the needs of the field commander. Having the ability to put the asset in In Spt, or DS (without pol) is a real advantage.
That argument doesn't wash. 9,5,12 and 35 SQNs RAAF were providing timely and effective RW support to Army units prior to the transfer, with squadrons or parts thereof deployed in the bush near the battalions in the field, AMCs for missions attending orders, representatives in the ground commander's HQ tasking the assets directly, good awareness of the objectives of the ground battle on the part of the aircrews and their commanders. Strange as it may seem, RAAF aircrew could comprehend what the ground troops were trying to achieve and work to enhance that. The primary roles of these squadrons was Army support.
Transfer of assets to the Army took place, and, surprise surprise, there were still only as many helicopters as there had been before, but with less experienced crews / maintainers, so the service provided actually took a hit, rather than being enhanced.
