Canberra, August 11: Australia is taking decisive action against the rapidly spreading H5N1 bird flu by initiating a vaccination program aimed at protecting rare and vulnerable bird species.
Agriculture, Fisheries, and Forestry Minister Julie Collins announced on Tuesday that the government has secured an initial 1,500 doses of the H5N1 vaccine. These doses will first be administered to captive birds that are at the highest risk of contracting this highly contagious virus.
According to a report by Xinhua News Agency, Collins stated, “We have been very clear that we cannot prevent H5 bird flu from spreading among wild birds, but we can take necessary steps to protect the species that are most at risk, and vaccination is now part of that strategy.”
She warned Australians that further spread of H5N1 could be expected in various parts of the country, along with a significant number of bird deaths and mass mortality events.
As of Monday, official figures indicated that Australia had confirmed 231 cases of H5N1. The virus was first detected in June, and the number of cases has surged by over 300 percent since the beginning of August.
Environment and Water Minister Murray Watt mentioned that consideration will be given to vaccinating wild birds where feasible, but captive birds will be prioritized for now.
Watt also highlighted that the government has strengthened captive breeding programs in zoos to protect rare and endangered birds. This initiative aims to ensure that even in the event of mass bird fatalities due to H5N1, these species can survive.
In an interview with ABC Radio on August 4, Watt expressed concerns about the potential for large-scale bird mortality events in Australia due to H5N1.
The first major indication of this risk emerged on August 3, when the federal government confirmed the first mass mortality event on the Australian continent involving a flock of Greater Crested Terns on an island off the coast of South Australia.
The impact of H5N1 is not limited to birds. In 2022, the virus was responsible for the deaths of an estimated 30,000 sea lions in South America. Additionally, between August 2025 and January 2026, around 13,359 South Elephant Seal pups on Heard Island, located in the Southern Ocean, are suspected to have died from H5N1.
Given the rapidly increasing cases and the severe impact on wildlife, Australia’s vaccination campaign is seen as a crucial step towards the conservation of rare and sensitive species.
