 Three decades later, the East – West Telegraph line was installed. Constructed between 1875 and 1877, it followed the same route across the Nullarbor and along the Great Australian Bight, after John Forrest retraced Eyre's route in 1870 and confirmed its suitability. Repeater stations were installed at Port Lincoln, Streaky Bay, Smoky Bay, Fowlers Bay, Eucla, Israelite Bay, Esperance, and Bremer Bay. Stations were latter added at Franklin Harbour (Cowell) in 1885, Yardea in 1896, and Balladonia in 1897.
