SYDNEY: Australian authorities on Wednesday confirmed the detection of the highly pathogenic H5 bird flu strain in a second state, raising concerns about the virus’s spread among migratory birds while officials seek to safeguard the country’s poultry industry.
The latest case was identified in South Australia after the virus was found in a migratory seabird, just days after Australia recorded its first H5 detection in Western Australia. The development marks a significant moment for the country, which had long remained free of the H5 strain that has devastated bird populations in many parts of the world.
Agriculture Minister Julie Collins said the new detection was concerning but not unexpected given the global spread of the virus through migratory bird routes. She noted that authorities have not observed any large-scale bird deaths linked to the outbreak and stressed that there is currently no evidence of infection within Australia’s poultry sector or broader agricultural production system.

Officials have also maintained that the risk to human health remains low, although surveillance and biosecurity measures have been intensified across affected regions. The H5 strain has caused severe outbreaks internationally, leading to significant losses in poultry flocks and wild bird populations. Its arrival in Australia has prompted heightened vigilance among producers and government agencies.
One of Australia’s largest poultry companies has already implemented strict lockdown measures at farms in Western Australia in an effort to prevent the virus from entering commercial operations.
The outbreak has also had implications for trade. Papua New Guinea temporarily suspended imports of Australian eggs and chicken products following the initial detection, although most restrictions have since been eased.
Authorities said ongoing monitoring of migratory birds and rapid response measures would remain critical in preventing the virus from spreading into commercial poultry farms and causing wider economic disruption.
The H5 strain of avian influenza has triggered outbreaks across multiple continents in recent years, leading to the deaths or culling of millions of poultry birds and causing substantial economic losses to the global poultry industry.
Health and agricultural experts have repeatedly warned that migratory birds are a major pathway for the virus’s international spread, underscoring the importance of surveillance, rapid detection and robust biosecurity measures.
