The Overland Telegraph

Adelaide to Darwin, 1872

The 3,178 kilometre line was built in less that two years and joined on 22 August 1872. It linked Australia to an undersea cable from Indonesia that came ashore at Port Darwin and made communication between Australia and the rest of the world possible in hours rather than weeks.  The project was under the direction of Sir Charles Todd, KCMG, MA, FRS, FRAS, FRMS, FSTE, Superintendent of Posts and Telegraphs. The first telegraph messages from overseas were received in morse code in this building on 22 October 1872 via the Overland Telegraph Line.
