Australia has warned that H5N1 bird flu is likely to spread further after the country recorded its first mass mortality event linked to the virus in seabirds. The alert follows confirmed infections in greater crested terns found off the coast south of Adelaide.
According to the details released, testing confirmed H5N1 in a group of 49 dead terns and 35 sick birds. The development marks a significant moment for Australia, where authorities are now facing a more serious wildlife outbreak involving a highly pathogenic strain of avian influenza.
The agriculture minister said the findings point to a likely wider spread of the virus. The warning reflects concern that more wild birds could be affected as officials monitor the situation and assess the risk of further transmission.
The outbreak adds to global concern about H5N1, which has caused major losses in bird populations in other parts of the world. In Australia, the confirmed seabird deaths south of Adelaide now stand as an early sign that the virus may become a broader challenge for wildlife health monitoring.
