Australia has recorded its first confirmed cases of H5 high pathogenicity avian influenza in local, non-migratory seabirds, marking a new phase in the country's response to the virus. While previous detections were limited to migratory seabirds arriving from sub-Antarctic regions, the recent identification of the virus in a greater crested tern in South Australia indicates the disease is now interacting with local wildlife populations. As of mid-July 2026, the national tally of confirmed H5 detections stands at 13, spread across Western Australia, South Australia, and New South Wales.
Despite this escalation, federal and state authorities maintain that the risk to human health remains low. There is currently no evidence of the virus spreading to commercial poultry farms or the wider agricultural sector, and no mass mortality events have been observed in wildlife. The government continues to emphasize that poultry products, including meat and eggs, remain safe for consumption when handled and cooked according to standard food safety practices.
National coordination is being led by the Department of Agriculture, Fisheries and Forestry, which is working closely with state agencies to monitor the situation. Surveillance efforts have been intensified, with authorities urging the public to report any sightings of sick or dead wildlife to the national Emergency Animal Disease Hotline. This reporting system is critical for early detection and helps scientists track the movement of the virus across the continent.
While the arrival of H5 bird flu in local species is a significant development, officials describe the situation as a managed biosecurity event rather than an uncontrolled outbreak. The government has allocated significant funding to support national response plans, including enhanced monitoring and biosecurity measures. Experts continue to study the genomic data of the virus to understand how it is moving through the environment and to refine protective strategies for the nation's poultry industry.
