Australia has confirmed its first-ever case of the highly infectious H5 avian influenza, detected in a brown skua found on a beach near Esperance, Western Australia. Local veterinarian Dr. Toni Howlett discovered the sick bird while walking, later followed by a second confirmed case in a Giant Northern Petrel identified by Dr. Alex Hockton. Both cases have prompted state authorities to activate emergency biosecurity protocols to contain the virus.
How was the H5 bird flu detected in Australia?
The detection of the H5 variant resulted from a collaboration between private veterinary clinics and the Department of Primary Industries and Regional Development (DPIRD). According to Dr. Toni Howlett of Swans Vets, she initially suspected the bird was suffering from botulism due to its dehydrated state. After transporting the bird, she worked with local wildlife carer Lori-Ann Shibish to facilitate testing. Five days later, her colleague Dr. Alex Hockton identified a second infected bird, a Giant Northern Petrel, based on clinical symptoms. Dr. Enoch Bergman, owner of Swans Vets, stated that this “early recognition” by regional staff was critical in establishing an immediate response.
Why is the Esperance region a focal point for this outbreak?
Veterinarians in the region had been preparing for a potential H5 incursion for approximately two years. Dr. Alex Hockton noted that Esperance’s geographical position on the south coast made it a likely entry point for migratory birds. The clinic had received specific training from DPIRD to recognize and report symptoms of exotic diseases. Agriculture Minister Jackie Jarvis confirmed that the state government invested in a network of private regional vets throughout 2023 specifically to bolster the state’s animal biosecurity response and surveillance capabilities.

What are the risks to Australia’s biodiversity?
Experts warn that the arrival of the H5 variant could be catastrophic for Australia’s vulnerable species. Unlike other regions where the virus has circulated for years, many Australian endemic species have no prior exposure to this strain. Because the virus is highly infectious, it poses a direct threat to seabird colonies and other emblematic wildlife. Dr. Alex Hockton emphasized that the current priority is to mitigate the risk of viral spread to keep both the environment and the public safe.
Did you know?
The brown skua, the species involved in the first confirmed case, is a subantarctic migratory bird. These birds travel vast distances, which is why scientists have long identified them as potential vectors for global disease transmission across hemispheres.
Frequently Asked Questions
Is the H5 bird flu in Australia dangerous to humans?
While the focus is on the impact on animal populations, the Department of Primary Industries and Regional Development (DPIRD) and local vets are managing the situation to ensure public safety. Authorities advise the public to avoid contact with any sick or dead wild birds.

What should I do if I find a sick bird on the beach?
Do not attempt to rescue or handle the bird. Leave it where it is and report it to the Emergency Animal Disease Hotline. Reporting helps officials track the movement of the virus.
Why are private vets involved in this response?
Private vets act as “first responders” in regional areas. Their training, funded by the state government, allows for rapid identification of exotic diseases before they can spread further into the ecosystem or agricultural industries.
