The Owen was the only Australian-designed service firearm of WWII. Evelyn Owen, an inventor from Wollongong, was 24 in July 1939 when he presented his prototype "Machine Carbine" to ordnance officers at the Victoria Barracks in Sydney.

Although somewhat bulky the Owen rapidly became very popular due to its reliability. It was so successful that it was ordered by the US and New Zealand. The Owen was used in front-line service in the Korean and Vietnam Wars. It remained a standard weapon of the Australian Army until the early 1960s, 1RAR, 5RAR and 6RAR on their first tours carried the weapon to Vietnam when it was finally declared to be unsuitable and was replaced with the American M15 and M16 automatic rifles.
