1,228,000 hectares
This vast park takes in all of Lake Eyre North and the Tirari Desert. It Protects an important desert wilderness. Lake Eyre has international significance, both for its large expanse of salt pan and its occasional floodings. The Tirari Desert is noted for its vast north-south dunes and salt lakes and in one, Lake Ngapakaldi, important fossil deposits have been discovered. Vegetation in the park tends to be low and stunted, consisting mainly of samphire, saltbush and bluebush, with some acacia and cassia. Lake Eyre has only been full of water three times in living memory (and those only in the last fifteen years).
