H5N1 bird flu confirmed in Coorong; conservationists seek $200M emergency funding

A migratory petrel found dead in the Coorong has tested positive for H5N1 bird flu, marking the 58th confirmed case in South Australia and triggering urgent warnings about the survival of one of the country's most ecologically vital wetland regions. The discovery comes weeks after more than 80 birds died from the virus in the state's southeast, a mass-mortality event that has left conservationists bracing for what could unfold across the Coorong's dense breeding grounds.

The Coorong is no ordinary patch of water. It is the setting for Storm Boy, the beloved novel and film centered on a boy and his orphaned pelican companion, Mr Percival. More importantly, it serves as a breeding and resting site for over 20,000 waterbirds each year and is designated a Ramsar wetland of international ecological significance. Within its boundaries, 48 migratory species depend on the site, along with countless native birds that breed there or shelter during hardship. The region's pelicans—iconic, visible, loved—now face a threat that spreads with terrifying efficiency through the very water that sustains them.

Craig Wilkins, national co-director of the Murray-Darling Conservation Alliance, described the outbreak as potentially the beginning of "a pretty horrific journey" for the basin and Coorong. The virus spreads rapidly among waterbirds because they breed in dense clusters and contaminate water through their droppings. Pelicans, swans, terns, and herons—species that inspire public affection and scientific concern alike—are all vulnerable. The timing could hardly be worse. Earlier this year, the Lower Murray region, including the Coorong, was declared critically endangered, meaning there is a 50 percent chance the ecosystem will collapse within a decade. The bird flu outbreak is another stress on a system already buckling under pressure.

The Murray-Darling Basin itself looms as the likely epicenter for bird flu impacts across Australia. It is the feeding and breeding heartland for migratory and wetland species across the continent. Without intervention, Wilkins warned, the consequences for waterbird populations could be catastrophic. The Australasian bittern, already reduced to an estimated 1,300 mature individuals in the wild, faces particular peril.

In response, the Murray-Darling Conservation Alliance and BirdLife Australia are calling on the federal government to commit $200 million over two years to a national wildlife resilience package. The funding would support emergency environmental water deliveries to extend breeding seasons and increase wetland availability, accelerated wetland protection and restoration, rapid investment in wildlife resilience measures, removal of avoidable pressures like habitat destruction and hunting, and enhanced surveillance and rapid response capability for future outbreaks. South Australia's Environment Minister Emily Bourke acknowledged the spread from seabirds into the breeding grounds where waterbirds shelter, while Acting Premier Kyam Maher noted the state has invested more than $11 million since 2022 in wildlife and industry support.

The spring breeding season is approaching. Without coordinated emergency action to restore wetlands and deliver environmental water before then, the Coorong's waterbirds—and the broader Murray-Darling ecosystem—face a reckoning that could reshape the region's ecology for decades.
