Cooper Floodplain below Windorah: Introduction

For years at a time, this is desert. Some 290 millimetres of rain falls here in an average year, the land lies cracked and pale, and the few waterholes shrink under a furnace sky. Then the Cooper comes down. Rain that fell hundreds of kilometres away in the Queensland highlands gathers into Cooper Creek and spills out below the town of Windorah across a 1,741-square-kilometre maze of shallow channels and swamps. And as the water spreads, the birds arrive, in their tens and hundreds of thousands, until a corner of the continent's dead heart becomes one of the most extraordinary wetlands in Australia.

Cooper Floodplain below Windorah: The Cast of the Flood

The roll call reads like a survey of inland Australia's waterbirds. Great egrets nested here in their thousands during the 2004 flood, alongside royal and yellow-billed spoonbills sweeping the shallows. Grey teal, pink-eared duck and plumed whistling duck rafted across the water ...

Cooper Floodplain below Windorah: Boom, Bust, and the Pulse of the Inland

Mon, 22 Jun 2026 00:00:00 GMT

Major floods reach this plain only about once every five years, and that irregular pulse is the whole logic of the system. The waterbirds of arid Australia are nomads and opportunists, sweeping in to breed explosively when the water arrives and dispersing when it dries. Sites lik...
