Bird flu outbreak threatens wildlife and poultry in Australia and New Zealand

The H5N1 avian influenza outbreak is causing significant ecological and economic disruption across Australia and New Zealand. In Australia, hundreds of cases have been confirmed in wildlife, including seabirds and mammals, raising fears of mass extinctions among vulnerable species. The virus has spread to regions such as the Illawarra and the Far South Coast, prompting government responses to protect both native fauna and the poultry industry.

The Australian government has announced a $145 million funding increase to address the crisis, with $125 million earmarked for biosecurity and $20 million for threatened wildlife. However, the Invasive Species Council has criticized this amount as “deeply unserious,” arguing it is insufficient to prevent catastrophic declines in biodiversity.

In New Zealand, three positive detections of H5N1 have been confirmed in the Wellington region. Industry experts warn that the virus could lead to the permanent closure of some poultry farms, particularly in the egg sector, as the disease may become a permanent presence.

Researchers are exploring mitigation strategies, including the potential use of edible bait vaccines to protect scavenging mammals like Tasmanian devils from consuming infected carcasses.
