Highly pathogenic H5N1 bird flu has been confirmed on the Australian mainland after a brown skua tested positive near Esperance, Western Australia. While no commercial poultry detections have been reported, Ingham’s Group has initiated a complete lockdown of its Western Australian operations to prevent the virus from entering the food supply.
How did H5N1 arrive in Western Australia?
The virus was identified over the weekend after a brown skua was found on a remote beach near Esperance. A giant petrel in the same area also returned a preliminary positive result for the H5N1 strain. Beyond these specific birds, reports indicate more than a dozen cases of sick or dead birds have been observed along the Western Australian coast.
Until this detection, Australia was the only continent on Earth that remained free of the H5N1 virus. Since 2021, the highly pathogenic strain has caused the deaths of millions of birds and thousands of marine mammals globally.
Australia’s status as the last continent free of H5N1 made this coastal detection a significant biosecurity event for the entire nation.
How is the poultry industry reacting to the threat?
Ingham’s Group, Australia’s largest poultry producer, announced a “complete lockdown” of its Western Australian sites on Monday. The company has stopped all nonessential access to its operations. Ingham’s is also requesting permission from the state government to move free-range chickens into indoor housing to minimize exposure to wild birds.
The announcement triggered immediate volatility in the stock market. According to Bloomberg, shares in Ingham’s dropped as much as 14% on Monday. This decline follows a broader downward trend; the company’s share price has fallen more than 23% year-to-date.
This biological threat arrives during a period of financial transition for the company. The Australian Financial Review reported on June 1 that the $777m firm was already in “turnaround mode” following a restructured contract with Woolworths.

What is the government doing to prevent a spread?
Australia’s chief veterinary officer, Beth Cookson, told ABC’s Radio National that the virus has not yet been detected in poultry or agricultural systems. However, Cookson noted that authorities are investigating whether the infected wildlife has already spread the disease into other animal populations.
“Our approach is to really learn from the overseas experience and look at the practical actions that can be put in place to mitigate the impacts as far as possible,” Cookson said on Monday.
Federal Environment Minister Murray Watt confirmed that the government has invested $113m into preparedness efforts, which included $11m in the most recent budget. Cookson and threatened species commissioner Dr. Fiona Fraser are currently briefing state and federal environment ministers on the situation.
Biosecurity experts suggest that maintaining strict access controls and transitioning free-range stock to indoor environments are the most effective immediate defenses against wild bird-borne pathogens.
