Kati Thanda–Lake Eyre, located in the Far North region of South Australia, is an endorheic lake known for its vast salt pan and low elevation. When filled with water, it becomes Australia's largest lake, covering up to 9,500 km2. The lake's salinity varies depending on water levels, with a pink hue appearing due to algae. Floods occur every few years, bringing temporary life to the area. Despite proposals to flood it with seawater, practical challenges have hindered such plans. Overall, Kati Thanda–Lake Eyre is a unique natural wonder that showcases the beauty and harshness of Australia's outback landscape.
