Austurias56 has it!
Technically the airfield is Stock Route, used initially by USAAF B-26's, but by the time the photos were taken (and the hangars erected) it was occupied by the USAAF 5th Air Service Command's Depot No.2. The airfield was no longer used as such but was connected to nearby Townsville (Garbutt) by taxiway. In the photo below you can see the dis-used runway and also in the distance Garbutt's 020 degree strip pointing directly at the camera.
