Australia on Saturday confirmed its first mainland case of the highly pathogenic H5N1 bird flu strain after a migratory seabird tested positive near Esperance, in Western Australia. The discovery, announced by Agriculture Minister Julie Collins, marks the first detection of the virus on the Australian continent, which had previously remained free of the disease.
The infected bird, identified as a brown skua, was found on a remote beach south of Perth and underwent testing that confirmed the presence of the lethal H5N1 subtype. “This is a concerning development, though not unexpected given the global spread of this virus,” Collins said in a statement released on Saturday. The case follows earlier detections in Antarctica and surrounding islands, raising concerns about the potential for further spread via migratory routes.
Prime Minister Anthony Albanese described the detection as “concerning” and pledged immediate government action to contain the outbreak. “We are working closely with state and territory authorities, as well as wildlife and agricultural agencies, to assess the situation and implement appropriate biosecurity measures,” Albanese said, echoing statements made earlier in the day. Authorities have not yet confirmed whether the virus has spread to domestic poultry or wild bird populations beyond the initial case.
The H5N1 strain, known for its high mortality rate in birds and potential to infect mammals, has caused widespread outbreaks across Europe, Asia, and the Americas in recent years. While human infections remain rare, public health experts warn of the risk of spillover events, particularly in communities with close contact to infected animals. Australia’s Chief Veterinary Officer has urged poultry farmers and bird owners to enhance biosecurity and report any signs of illness immediately.
In response, Western Australia’s Department of Primary Industries and Regional Development has established a control zone around the detection site and is conducting surveillance of wild and domestic birds within a 10-kilometre radius. The department confirmed that no commercial poultry farms are located within the restricted area. Meanwhile, national biosecurity protocols have been elevated to “emergency response” level, with increased screening at airports and ports.
Global health and agricultural bodies, including the World Organisation for Animal Health (WOAH), have been notified. “This underscores the need for international cooperation in monitoring and responding to zoonotic diseases,” a WOAH spokesperson said. Australia’s status as one of the last regions free of H5N1 had been a point of pride for its agricultural sector, which exports billions of dollars’ worth of poultry and egg products annually.
As the situation develops, authorities are urging the public to avoid contact with sick or dead wild birds and to report sightings to local wildlife agencies. The government has also reiterated that the risk to human health is currently low, but remains under close watch.
