The General Purpose Uniform (GPU) is the working uniform of the Royal Australian Air Force. The GPU is not intended to serve as tactical battledress and, despite the resemblance of its fabric to digital camouflage, includes relatively high-visibility shades of blue.
The General Purpose Uniform is to replace the Disruptive Pattern Combat Uniform, also worn by the Australian Army, for general base duties and in non-warlike environments such as humanitarian tasks and Defence assistance to the civil community.
