The Nomad is designed and built by the Government Aircraft Factories in Australia in two models. These are the short-takeoff-and-landing (STOL) Nomad N22B and the Nomad N24A commuter aircraft. Variations on the basic aircraft include the Mission Master, the Search Master for maritime surveillance work, and a photographic and mapping model. The aircraft have proven successful in many countries, often flying over rugged terrain in climates ranging from tropical to subarctic. Its STOL capability, originally developed for Australian military use, has made it ideal for operations in rugged areas such as the highlands of Papua, New Guinea. The N22B, capable of carrying up to 12 passengers, can take off in only 800 feet. The larger N24A is a later development of the basic aircraft capable of carrying more passengers and cargo.

The Nomad is characterized by simplicity of construction and systems, which contribute to its economy of operation. Its two Allison 250-B17C turboprops are rated at 420 shp, producing more than two horsepower per pound of engine weight. The B17C offers an improved single-engine high-altitude performance capability and a more rugged gearbox. The GAF was renamed the ASTA (Aerospace Technologies of Australia) and later acquired by Rockwell in 1996.
