===Telegraph===
The need for a communications link across the continent was the spur for the development of an east–west crossing. Once Eyre had proved that a link between South Australia and Western Australia was possible, efforts to connect them via [[telegraphy|telegraph]] began. In 1877, after two years of labour, the first messages were sent on the new telegraph line, boosted by eight [[repeater]] stations along the way. The line operated for about 50 years before being superseded, and remnants of it remain visible.
