Murray-Darling river authority accused of 'ignoring climate science' over mass fish deaths

The authority that oversees Australia's largest river system was accused of "maladministration", "gross negligence" and ignoring climate science Thursday, as its waterways were carpeted with hundreds of thousands of dead fish.

A Royal Commission report into the Murray-Darling Basin Authority -- which happened to coincide with a series of mass fish kills -- was scathing in its assessment, accusing the body of illegality.

The Murray-Darling Basin is a river network sprawling for one million square kilometres (400,000 square miles), about twice the size of Spain.

It affects the livelihood of millions of people, but it had been over-exploited for years and seriously depleted by drought.

A South Australian inquest said the authority acted unlawfully in setting water levels while it "completely ignored" climate change projections.

"Politics rather than science ultimately drove the setting" of limits on the amount of water that could be taken out of the river, the report said.

The commission charged that the authority failed to be guided by "environmental priorities", as required by law. "It is an unlawful approach. It is maladministration."

An investigation by the national broadcaster the ABC in 2017 found billions of litres slated for environmental flows was being used to irrigate farmland in New South Wales.

A review of water management compliance in 2017 found inconsistent and poor enforcement in some states.

The report comes as debate rages over a series of mass fish kills over the past few weeks in rivers connected to the Murray-Darling.

Up to a million were killed last month -- with scientists pointing to low water and oxygen levels as well as possibly toxic algae -- in drought battered eastern Australia.

The royal commission recommended a complete overhaul of the water river management plan, with revised levels based on "the best available scientific knowledge".
