HMAT Bulla was built as Hessen for the German Line Norddeutscher Lloyd in 1905.[1] It was seized by Australian forces on September 3, 1914, when it sailed into Melbourne, being unaware of the outbreak of World War I.[2] It was a troop transport in the First World War, and then transferred to the Commonwealth Government Line of Steamers in 1918. It was sold in 1926 to W. Schuchmann, who renamed it Weissesee[3]
Weissesee was bombed and sunk by aircraft at Hamburg, Germany, on 25 July 1943. The wreck was raised in 1949 and scrapped.[4]
