Lake Eyre is the largest lake in Australia, covering 9,500 km2 (3,668 sq mi). When the lake is full, it has the same salinity level as the sea, but as the lake dries up and the water evaporates, salinity increases. The lake was named by Europeans in honour of Edward John Eyre, who was the first European to see it, in 1840. The lake's official name was changed in December 2012 to combine the name "Lake Eyre" with the indigenous name, Kati Thanda. The native title over the lake and surrounding region is held by the Arabana people.
