Who first explored central Australia?

Even by the 1830s, central Australia was still a great mystery. Several people had tried to explore the interior but had been defeated by desert, lack of water and hostile natives. One of these was Edward Eyre, who had failed twice. His third attempt also seemed hopeless but finally, after an appalling journey of 2,000 km, Eyre and Wylie, his faithful aborigine servant, reached the south-west coast at Albany.
