HMS J 1 was a J class submarine laid down at Portsmouth Dockyard and was launched in November 1915. All the J submarines were assigned to 11. Submarine Flotilla , and J 2 spent the war years patrolling in the North Sea before she was transferred to the Mediterranean in 1918 where she engaged the German uboat UB57. In March 1919 all the remaining J class submarines were gifted to the Royal Australian Navy. They arrived Australian waters in July that same year, and were all taken out of active service for maintenance. After a few local exercises they were all stricken from the Navy lists and decommissioned in July 1922. J1 was scuttled 26. May 1926 outside Port Philip Heads.The wreck was found by sport divers in 1984, and rest today on her keel with a slight listing to port on a depth of 34 to 38 meter in Bass Strait. Also see the wrecks of her sister ships HMAS J2 HMAS J3, HMAS J4, HMAS J5, HMAS J7 and HMS J6 in England.
