Lake Eyre is the largest lake in the northern part of South Australia, and fascinating for a number of reasons. At 15m below sea level, it is Australia's lowest point, and most of the time it is a saltpan. After a monsoon season in Australia's Gulf region, the waters flow through the Queensland outback and ampty into Lake Eyre, partially filling it or, in rare years, completely filling it. At this time, the lake becomes alive with migratory water birds which fly in from other parts of Australia and start their breeding cycle there. Although the lake is usually dry, fish species seem to emerge out of hibernation, quickly populating the lake. One unique fish species is the Lake Eyre hardy-head. Other species of creatures are found only at Lake Eyre, such as the tiny Lake Eyre Dragon, which has special eyelashes that protect it from the glare of the summer sun and white salt crystals on the lake surface. There are various frog species which bury themselves during the long dry spells, reemerging after the lake fills.

These birds use the area as breeding grounds until the waters dry up once more.Once, there was a sailing club that took advantage of the lake's waters when they were filled, but sailing is no longer permitted on Lake Eyre.
