Coongie Lakes, Goyder Lagoon & Kallakoopah Creek
In the heart of Australia is an incredibly diverse landscape where desert and vast wetlands support hundreds of species, and millions of birds.
Lake Eyre Basin
The Lake Eyre Basin has a long past—let's make sure it has a living future.
At the heart of Australia, a complex system of waterways drain inland never reaching the sea. The result is an incredibly diverse landscape where deserts and vast wetlands support hundreds of species and millions of birds.
The Lake Eyre Basin encompasses the heart of Australia, comprising some of the world’s most extensive desert, rivers and wetlands.
It represents one of the biggest inland draining water systems on the planet, and the only one in Australia to not flow into the ocean. Covering 1.2 million square kilometres, it's six times the size of Victoria and straddles South Australia, the Northern Territory, Queensland and the western fringes of New South Wales.
For millions of years its complex system of waterways, lakes and underground aquifers has been sustaining incredible environments that play host to remarkable biodiversity.
First Nations people have lived in this fluctuating landscape for tens of thousands of years. Over seventy languages can be ascribed to the region that is alive with songlines, trade routes, and language groups.
When rainfall saturates Channel Country in Queensland's south-west, filling the Diamantina and Georgina Rivers and the Cooper Creek, it transforms an arid landscape into a network of lush waterways. Water flows down through the desert, enabling carpets of wildflowers to spring across vast areas including the wetlands of Goyder Lagoon and the Coongie Lakes region in South Australia. When the wetlands fill, water then flows through the Kallokoopah Creek section of the Munga-Thirri, where over 900 species of flora and fauna can be found.
Sometimes there is enough water to continue the journey south until it floods the lowest point in Australia at 15 metres below sea level, what the Arabana people call Kati Thanda (Lake Eyre). When Kati Thanda floods it turns bare, red and white desert into a huge wetland, becoming home for millions of birds.
A world under threat
The Lake Eyre Basin is a vast system of water, people, flora and fauna that has been working in harmony for millennia, and yet the relatively recent industrial expansion of fossil fuel exploration and cattle farming threatens all of that.
Drilling for oil and gas and the damaging infrastructure that comes with it—roads, gas wells, pads, pipelines, wastewater storage ponds—risk disrupting the fragile network of waterways that feed wetlands and water holes throughout this globally significant system. Desert ecosystems that depend on the water going where it’s intended to go could be wiped out if these water systems are disrupted or polluted by the expansion of dirty oil and gas.
The Wilderness Society is now working across the Lake Eyre Basin to protect these sensitive environments including Goyder Lagoon, Coongie Lakes region and the Kallakoopah Creek section of the Munga-Thirri/Simpson Desert National Park.
The Lake Eyre Basin must be protected and respected. Below, find out how the Wilderness Society is working with the community to do this.
Munga-Thirri / Simpson Desert
Thanks to your support, together we've helped deliver the biggest national park in Australia in the Munga-Thirri / Simpson Desert, protecting 3.6 million hectares of undamaged desert ecosystems. However, even now, the threat of fossil fuels remains.
Channel Country
The free-flowing rivers of the Channel Country in the south-west corner of Queensland replenish the Simpson Desert and Kati Thanda to the south. Developing these delicate rivers and floodplains for oil and gas poses a terrible risk to the future health of the whole of the Basin and to the overland flows—the lifeblood that feeds the heartlands of Australia. Thanks to your support, these rivers and floodplains are now protected from the ongoing expansion of dangerous oil and gas.
