As a contribution to this year's commemoration of the Bombing of Darwin, the local branches of the Mapping Sciences Institute and the Surveying and Spatial Sciences Institute have organised an exhibition, Mapping for the War in the North, which tells the story of how the military surveyors and cartographers responded to a major deficiency in the country's military capability at the start of the Second World War – the lack of maps of northern Australia suitable for military purposes. The exhibition, in the NT Library in Parliament House, runs until 17 March, and is accessible during the Library's opening hours.
