The Austen ('Australian Sten') Mk I was a 9x19mm submachine gun developed in 1942 as Australia's hybrid wartime answer to the British Sten and German MP40. It married the Sten Mk II's barrel, receiver, and trigger group with the MP40's folding stock, telescoping bolt cover, and separate firing pin, fed from a side-mounted Sten-pattern magazine. Despite being mechanically reliable, it was overshadowed in Australian service by the homegrown and beloved Owen Gun.
