News release - "Australia's first submarine which was lost during the outbreak of World War I might have been found off Papua New Guinea. It has been more than 90 years since Australia's first-ever submarine, the AE1, was last seen near the Duke of York Islands in East New Britain. The 60-metre sub and its entire crew disappeared during a routine mission in 1914. Sonar detectors on board Australian Navy ship HMAS Benalla detected an object a similar shape and size to that of the AE1 sub, near Rabaul. The location has been marked for future investigation and will be kept secret to deter trophy hunters." My comment: They should leave it as a War Grave - like the other WW1 Oz Sub on the bottom of the Dardenelles.
