Australia Detects Third H5N1 Bird-Flu Case in Migratory Seabird
6/24/2026, 10:20:02 AM
Third Confirmed H5N1 Case in South Australia
A giant petrel (Macronectes giganteus) found on Knights Beach, Fleurieu Peninsula, tested positive for the highly pathogenic H5N1 avian influenza virus on 19 June. The bird was rescued on 14 June, and state authorities confirmed the result on 24 June, marking the third mainland case after two detections near Esperance, Western Australia.
First Mainland Detections and Ongoing Surveillance
The first Australian mainland detections were a brown skua (Stercorarius antarcticus) and a northern giant petrel (Macronectes halli) on a remote beach near Esperance on 14 June. Prior to these events, 774 bird samples had been tested in South Australia and 11 in Western Australia, with 94 public reports of dead or sick birds in the preceding three days.

Timeline of Key Events
- 14 Jun – Brown skua and giant petrel found dead near Esperance (WA).
- 14 Jun – Giant petrel rescued at Knights Beach (SA).

- 24 Jun – SA confirms positive result; federal and state ministers hold joint press conference.
Data & Statistics
- Confirmed cases: 3 birds (2 WA, 1 SA).
- Samples tested: 11 (WA), 774 (SA).
- Funding: A$8.1 million allocated to SA’s Department of Primary Industries and Regions; A$11.2 million federal commitment for at-risk species; total national preparedness investment A$113 million.
- Surveillance: Ground and drone surveys at sea-lion breeding sites; hotline 1800 675 888 receives >100 reports daily.
Why It Matters
The virus threatens endemic wildlife, including Australian sea lions (Nuyts Reef colony), orange-bellied parrots, and Tasmanian devils, and could disrupt the poultry sector despite current biosecurity. Human infection risk remains low, but the strain’s capacity to infect mammals raises precautionary concerns.
Official Statements & Responses
South Australian officials emphasized rapid testing and the provision of antiviral medication to volunteers. Federal Minister Collins assured the public that chicken meat and eggs are safe and that no mass mortality has been observed. WA Minister Jarvis noted the absence of evidence for spread to native fauna. The Australian Chief Veterinary Officer highlighted that repeated introductions could increase spill-over opportunities.
Criticism & Opposition
The AVA called for an additional AU$7.5 million to support veterinarians handling wildlife cases. The Invasive Species Council urged AU$200 million over two years to bolster resilience of vulnerable species, arguing current funding may be insufficient.
On-the-Ground Reports
Marine-tourism operator Rod Keogh discovered three dead seabirds at Fowlers Bay, reported them to PIRSA, and warned of potential impacts on the nearby sea-lion population. Local wildlife rescue groups facilitated sample collection within hours.
Conflicting Reports & Gaps
Western Australia’s third case remains unconfirmed pending CSIRO analysis. Samples from a dead porpoise near Esperance are also being tested, but the timeline for results is unclear. WA chief veterinary officer Michelle Roden indicated the strain is unlikely to spread mammal-to-mammal, yet surveillance of mammals continues.
Verbatim Quotes
- “Once that was drawn to the attention on June 19 to the relevant authorities in South Australia, we responded quickly and enabled and facilitated active testing of those birds for H5 bird flu,” — Peter Malinauskas, SA Premier
- “Generally with mammals, the way that they get infected is actually consuming a bird, so usually it's animals that eat birds,” — Michelle Roden, WA Chief Veterinary Officer
- “We can’t overstate how significant this moment is for Australian wildlife,” — Kate Millar, BirdLife Australia CEO
- “Readiness is not free,” — Dr Diana Barker, AVA President
- “This strain of bird flu has caused huge die-offs of birds and sea mammals.” — Wayne Boardman, Wildlife Veterinarian, Adelaide University
- “We are working to determine whether or not the H5 bird flu has established in the wildlife or established in Australia, other than these two isolated birds,’ Collins told reporters.” — Julie Collins, Federal Agriculture Minister
What’s Next
Authorities will expand testing to additional shorebirds and marine mammals over the next week, maintain drone monitoring of sea-lion colonies, and review funding allocations for wildlife resilience. The CSIRO’s confirmatory results for the WA suspected case are expected within days, guiding any further movement restrictions or biosecurity actions.
