The Murray-Darling Basin is one of the world’s largest and most productive river basins providing one third of Australia’s food supply and accounting for $19 billion of agricultural output. It harbours some of our most important natural assets, supporting a diverse array of animals, plants and ecosystems of national and international significance.

With the damaging effects of drought, unsustainable agriculture, over-exploitation, poor management and other factors, the future of the Murray-Darling Basin and all life that depends on it is at considerable risk.

Ecosystem at risk

In early 2019, if you’ve heard about the mass fish deaths and devastation caused by drought in New South Wales, you know how heartbreaking it is to see fish dying because there is not enough water in the Murray-Darling Basin. In a recent assessment of overall ecosystem health, it’s no surprise that more than 80% of the Murray-Darling Basin’s river valleys were rated as being in poor or very poor health.

If this news saddens you, you’re not alone. You know that action needs to be taken to save the Murray-Darling Basin. Every little thing you, your family and friends are doing to help nature gives us hope that, together, we can make a difference. 

Our ecosystems are on life support

Take the lead and help us fight to protect them now and for the future of our planet.

With help from supporters like you, we're proving that the destruction of our natural world is not inevitable. 

Together, we can achieve large-scale victories across Australia—victories rooted in solid science, collaboration and a strategic framework for change. 

How we’re protecting the Murray-Darling Basin

The Nature Conservancy focuses on large-scale impact across Australia. Here is some of the work we're doing to help protect habitat in the lower Murray-Darling Basin:

We're reversing the damage at Gayini to reinstate a more natural flooding regime to give our iconic species a fighting chance to thrive again. Gayini Nimmie-Caira is an 88,000 hectare property in the lower Murray-Darling Basin, known as the "Kakadu of the South”. 

It's a remarkable place that's one of the few significant remaining areas of river red gums in Australia. During the wet season, the lakes and other wetlands in the area join up to become an inland sea that makes the perfect breeding ground for threatened species such as the Blue-billed Duck, Southern Bell Frog, and the Murray Cod.

Balancing water for people and nature

We established the world’s first impact investing project in Australia with the Murray-Darling Basin Balance Water Fund. 

The purpose of this innovative fund is to provide water security for farmers, while protecting culturally significant wetlands that support threatened species and ecosystems. 

The fund invests in permanent water rights in the Southern Murray-Darling Basin and allocates those rights in a smart way. 

When water is abundant and agricultural demand is lower, more water will be made available to local wetlands. When water is scarce and agricultural demand is higher, more water will be made available to irrigation. 

This approach optimises agricultural and environmental outcomes by replicating the natural wetting and drying cycles of the Basin. It’s a win-win approach, aligning the interests of people and nature.

The first wetland to receive water recorded an 800% increase in aquatic plant diversity, 135% increase in bird diversity, 250% increase in bird abundance and 46% increase in tree canopy health.

Nature CAN'T wait

We need people like you who understand nature’s struggles to stand with us.

It's going to take everything we've got to keep nature healthy and whole.

Australian researchers believe we are getting dangerously close to a threshold where whole ecosystems could collapse. 

There are so many natural places that need to be cared for. And like all conservation projects, it takes time and your unwavering support. Every donation over $2 is tax deductible. We urge you to make the most generous gift you can.
