| Notes | The Austen was developed to meet the demands for a sub-machine gun, the British and Americans were in no position to supply Australia in 1942 so they made their own modelled on the Sten, the Austen was not as reliable as the Owen, but due to demand the Austen was issued to Australian troops and served until 1945 but then declared obsolete. |
