Welcome to Eyre Highway (The Nullarbor)
John Eyre was the first European to cross this unforgiving stretch of country in 1841. After the 1877 telegraph line was laid, miners trekked to the goldfields under blistering sun and through freezing winters. By 1941 a rough-and-ready road carried a handful of vehicles, and in 1969 the road was sealed to the SA border. In 1976, the last coastal stretch was surfaced, with the Nullarbor region ending at the cliffs of the Great Australian Bight.
From Norseman it's 720km to the SA border, and a further 950km to Port Augusta. From Port Augusta, it's another 300km and you reach Adelaide.
