Outbreak of H5 bird flu in Australia’s migratory seabirds and surveillance efforts
Consensus Summary
Australia is facing its first confirmed cases of H5 bird flu, a highly pathogenic strain, detected in migratory seabirds since late June [DATE UNVERIFIED]. Five cases have been confirmed across Western Australia and South Australia, with the first case identified last month in a brown skua at Cape Le Grand in WA. The outbreak has since spread to New South Wales, where a giant petrel near Hawks Nest tested positive for H5 influenza, marking the first suspected case on the east coast. Both state governments have emphasized that poultry flocks remain unaffected, and surveillance efforts have been in place for years, including preparations following an H7 outbreak two years ago. Public reports of sick or dead birds have surged, with WA receiving 375 reports since the first suspected case was announced last Friday, though most have tested negative. Authorities are increasing surveillance and coordinating nationally to monitor the situation, as the virus poses risks to both wildlife and agriculture.

Points of Difference
Details reported by only one source:
- The New South Wales government said last week it had surveillance in place for early detection following the arrival of H5 bird flu in other parts of Australia
- The NSW agriculture minister, Tara Moriarty, stated that the disease had not been detected in any poultry flocks, captive or other wild birds in NSW
- Initial testing at NSW labs confirmed the petrel was positive for H5 influenza, pending further confirmation by the Australian Centre for Disease Preparedness
- The fifth confirmed or suspected case in Australia was reported on Sunday 21st of June, with five giant petrels found on Roses Beach near Esperance in WA
- Only one of the five petrels tested positive for H5 bird flu, while the other four returned negative results
- WA Agriculture Minister Jackie Jarvis reported 375 public reports to the emergency animal disease hotline since the first suspected case was announced last Friday, with 43 prioritized for investigation and 12 negative test results
- An emergency meeting was convened on Thursday with the Wildlife Emergency Advisory Group to discuss Australia’s response to the outbreak
- The public has been urged to report sick or dead birds to the Emergency Animal Disease hotline on 1800 675 888
Contradictions
Conflicting information between sources:
- The Guardian states 'five cases have already been confirmed since late June,' while ABC refers to 'the fifth confirmed or suspected case in Australia,' implying the fifth case is still under investigation
- The Guardian mentions 'four in Western Australia and one in South Australia' as confirmed cases, while ABC states 'two cases of the deadly avian influenza have been confirmed so far in migratory seabirds in WA, and one in South Australia,' suggesting a discrepancy in confirmed vs. suspected cases
