Lake Eyre: Introduction

It is a blinding white salt pan stretching to every horizon, the lowest place in Australia at around fifteen metres below sea level, so flat and so bright that pilots crossing it can lose the line where ground meets sky. The Arabana people, on whose country it lies, have known its moods for far longer than any map, and their name, Kati Thanda, carries that long acquaintance. Then, perhaps three times in a century, everything changes. Water that fell as monsoon rain hundreds of kilometres away in Queensland finds its way down desert channels over weeks and months, and the dead salt flat becomes the largest lake on the continent - up to 9,500 square kilometres of shallow water where, days before, there was only crust.

Lake Eyre: The Patience of the Basin

Lake Eyre is the drain at the bottom of an enormous endorheic basin - a sealed-off region where rivers flow inward and never reach the sea.

As the water spreads, life detonates: dormant brine shrimp hatch, fish carried down the rivers breed in astonishing numbers, and then come the birds - pelicans, banded stilts, avocets, gulls and terns - in flocks of sta...

Lake Eyre: Pink Water and the Sailing Sky

Mon, 22 Jun 2026 00:00:00 GMT

When the water saturates with salt, the alga Dunaliella salina blooms and floods the surface with beta-carotene, turning vast stretches of the lake a startling shade of pink. The salinity climbs f...

Lake Eyre: The Day the Salt Flat Held a Record

Mon, 22 Jun 2026 00:00:00 GMT

Photo credit Phanly, CC BY-SA 3.0. On 17 July 1964, the salt flat held something other than water: it held the fastest car on Earth. Donald Campbell brought his turbine-powered Bluebird-Proteus CN7 to the dead-flat expanse of Lake Eyre, gambling that its endless smooth surface could carry a machine to 500 miles pe...
