Overland Telegraph LinePrint Page Print this page

The plaque commemorates the reception of the first messages from overseas via the new line in 1872. The 3178 kilometre line was built in less than two years and joined on 22 August 1872. 

The Overland Telegraph Line 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 Post and Telegraphs.
