World Connections 1872

In 1872, 150 years ago, the Overland Telegraph connected Australia to the rest of the world through Adelaide, South Australia. Eight to ten weeks wait for international information became 24 hours through electronic transmission. This system became the progenitor of the internet.

Charles Todd, astronomer, meteorologist and electrical engineer, was charged with building the Overland Telegraph line from Cable Beach, to Darwin, through Alice Springs to Port Augusta.

The Royal Geographical Society of South Australia will be holding an exhibition related to Charles Todd, who was a Councillor of the Society from 1889-90, and the Overland Telegraph in May 2022 in the Society’s Rooms.
