On formation, No. 44 Wing controlled six radar stations in the Darwin area. Over the next two years it established seventeen new stations throughout the North-Western Area, relocated ten, and disbanded two others, and also set up twelve homing beacons. It further established supply, maintenance and repair facilities, as well as communications with No. 5 Fighter Sector Headquarters to coordinate air defence in the region. Hannam was mentioned in despatches for his achievements. After the fighting in New Guinea had ceased, the threat of air raids on mainland Australia eased, and No. 44 Wing was disbanded on 22 August 1944.
