A distinguishing feature of Australian Beauforts was a larger fin, which was used from the Mk VI on. Armament varied from British aircraft: British or American torpedoes were able to be carried and the final 140 Mk VIII were fitted with a locally manufactured Mk VE turret with .50 cal machine guns. A distinctive diamond-shaped DF aerial was fitted on the cabin roof, replacing the loop antenna. Other Australian improvements included fully enclosed landing gear and Browning M2 machine guns in the wings. Some were also fitted with ASV radar aerial arrays on either side of the rear fuselage.
