Agriculture Minister Julie Collins stated that there is no evidence yet of the virus on Australian farms, which have been locked down as a precaution.

Story summary

Australia has confirmed its first mass death of seabirds from H5N1 bird flu, with about 50 greater crested terns killed off the coast south of Adelaide. The deaths were found on rocks off Cape Jaffa, which is 250 kilometers from Adelaide, and were confirmed by testing to be caused by H5N1 bird flu. This is the first time a mass mortality event has been confirmed in Australia, and the country's Agriculture Minister, Julie Collins, warned that Australians can expect to see more spread of the virus and larger numbers of wildlife affected. There is currently no evidence of the virus on Australian farms, but many have locked down their poultry flocks since June. The H5N1 bird flu has already caused significant losses in other countries, killing hundreds of millions of birds and mammals and infecting cattle in the United States.

Why this leaning score
The article presents a neutral tone, but slightly tilts towards a cautious or warning-oriented narrative, as evidenced by phrases such as 'the risk of a wider spread' and 'significant losses.' This framing is balanced by the inclusion of factual information and quotes from the Agriculture Minister that provide context and emphasize preparedness measures taken by Australia.
Written under an earlier scoring contract, which gave a paragraph rather than checkable quotes. Re-analysing this article replaces it.
