The Siege of Toma was a bloodless action during the First World War on the island of New Pomerania (now New Britain) between 14–17 September 1914 as part of the occupation of German New Guinea by the Australian Naval and Military Expeditionary Force (AN&MEF). Australian forces had been dispatched to seize and destroy German wireless stations in the south-west Pacific because they were used by the German East Asian Cruiser Squadron of Vice-Admiral Maximilian von Spee which threatened merchant shipping in the region. New Zealand provided a similar force for the occupation of German Samoa.
