The H5 strain of bird flu has been confirmed in South Australia, marking the second Australian state to detect the virus following earlier cases in Western Australia. According to South Australian Premier Peter Malinauskas, a southern giant petrel tested positive after being found unwell at Port Elliot on June 14. This brings the national count of confirmed or suspected cases to four, as federal and state authorities coordinate monitoring and response efforts.
How is the H5 bird flu spreading in Australia?
Australian authorities have traced the likely source of the initial H5 infections to migratory seabirds arriving from subantarctic territories. Chief Veterinary Officer Beth Cookson stated that genome testing on a brown skua—the first confirmed case in Western Australia—linked the strain to the Heard Island and McDonald Islands region. This area has seen significant wildlife mortality, including thousands of southern elephant seal pups and hundreds of king penguins, throughout 2025 and 2026. While the virus has now appeared in multiple states, Federal Agriculture Minister Julie Collins confirmed that there remains no evidence of the virus spreading to domestic poultry or local native wildlife populations.
Wildlife rescue organizations play a critical role in early detection. In the South Australian case, a volunteer-run facility in Goolwa cared for the infected petrel for several days before authorities were alerted via social media, leading to the eventual positive test by the CSIRO.
What are the risks to Australia’s poultry industry?
The detection of H5 in migratory birds has prompted immediate trade and biosecurity responses. Papua New Guinea briefly suspended imports of Australian poultry products this week, though Federal Agriculture Minister Julie Collins confirmed that this restriction was lifted by Wednesday. To mitigate risk, state governments are maintaining hotlines for the public to report sick or dead bird life. Premier Malinauskas noted that officials are currently in contact with rescue volunteers who handled infected birds, with protocols in place to provide antiviral treatments like Tamiflu if human exposure is suspected.
How does the current outbreak compare to global trends?
The H5 strain identified in Australia is part of a global wave of highly pathogenic avian influenza that has devastated wildlife populations worldwide. The Invasive Species Council has highlighted a contrast between current government responses and the long-term needs of the environment. While the government’s active monitoring is acknowledged, the council’s policy director, Carol Booth, argues that $200 million in urgent conservation funding is required. This funding would aim to reduce secondary threats to native species, ensuring they are resilient enough to survive if the virus spreads further into the continent’s interior.
Pro Tip: Reporting Sick Wildlife
If you encounter a bird that appears lethargic, “beach washed,” or dead, do not handle it. Contact your state’s agriculture department or local wildlife rescue hotline immediately to ensure professional assessment and safe sample collection.
Frequently Asked Questions
- Is the H5 bird flu currently in Australian poultry? No. As of late June, the federal government reports no evidence of the virus spreading to domestic poultry farms.
- What should I do if I find a dead bird? Do not touch it. Report the location to your state’s primary industries or agricultural department via their official hotline.
- Is this virus dangerous to humans? While the virus is primarily a wildlife concern, authorities are monitoring anyone who has had direct contact with infected birds and can provide preventative antivirals if necessary.
- Where did the virus originate in Australia? Scientists have traced the infection to migratory seabirds arriving from the subantarctic, specifically the Heard Island and McDonald Islands region.
