Millions of dead carp will fill the Murray-Darling Basin after the government releases a targeted virus. Scavengers like turtles and crayfish might help – as long as we protect them.
Malcolm Turnbull likes to portray himself as a pragmatist who wants this parliament to work.

Malcolm Turnbull didn’t actually trade his first-born this week but it felt like it might come to that. In a whatever-it-takes frame of mind, the government conceded a great deal to get its legislation…
The Murray-Darling is a complex freshwater ecosystem.

Many pet fish end up in ponds, fountains and waterways. But before ditching your goldfish in the park, stop and think about the viruses you could also be releasing.

For the Barkindji people, the Darling River has been a symbol of Aboriginal survival since colonial times. Now, the once busy NSW town of Wilcannia is in danger of losing its water.
Northern rivers could increase Australia’s irrigated land by 50%. But we need to think about the environmental impacts.

It's full steam ahead for bringing vast increases in farming to northern Australia. In fact, probably too fast to adequately consider the environmental impacts.

As El Nino looms, the Murray-Darling is facing another drought. But after almost a decade of investment in water trading and other policies, its prospects are better this time around.
The Murray-Darling: a complex river system with a complex set of regulations to match.

Water isn't straightforward. And by putting the Nationals in charge of policy for water assets like the Murray-Darling Basin, the government will trigger a complex round of bureaucratic musical chairs.
Soil and water are crucial resources that need to be carefully studied and preserved.

There will be increasing demands placed on our soil and water in coming years, so we need greater research into how to preserve and maintain these precious resources.
Go with the flow: scarce water has allowed Outback species to persist for millennia, where otherwise they might have died out.
Jenny Davis
The Outback covers 70% of Australia, and its water is precious and scarce. Yet there is no joined-up plan to monitor and manage Outback water, despite the wealth of species and communities that depend on it.

Imagine a future where the yearly flow into one of the largest water reservoirs of a major Australian city could halve within 70 years. This is a scenario that Adelaide could face if the world continues…
Queensland’s cuts to water red tape could leave outback bores high and dry.

On Wednesday, Queensland’s parliament passed water reform legislation that will make it easier to take and use water, particularly for large mining and agriculture projects. The state government also recently…
Australia’s north is home to many pristine rivers, but most national parks are focused on land-based conservation.

Freshwater ecosystems such as rivers, lakes and wetlands are precious. They contain several-times more vertebrate species per unit area than land and ocean environments, and they are more degraded. Protected…
Spending on water-saving infrastructure could expose Murray-Darling farmers to debt and drought.

The federal government’s approach for the Murray-Darling Basin Plan has shifted again, and now favours water-saving infrastructure over purchasing water rights. But is it the right move? The new scheme…
Carp have spread throughout Australia’s waterways - but CSIRO is hoping to bring a new genetic weapon to bear on them.

A genetic modification that creates male-only populations could give us a new weapon against invasive fish such as carp that plague our waterways. “Daughterless technology”, which works by removing females…
Selling water back to farmers could work out for the Murray River too.

The Commonwealth Government’s decision to sell up to 10 billion litres of its water allocation in the Murray-Darling Basin back to farmers could prove to be a win-win for irrigators and the river. On the…
The Murray River was listed as critically endangered on August 5, the day before the Australian federal government went into caretaker mode before the election campaign. The Weekly Times claimed that this…
Australia is famous for its natural beauty: the Great Barrier Reef, Uluru, Kakadu, the Kimberley. But what about the places almost no one goes? We asked ecologists, biologists and wildlife researchers…
