Australia pledges action on H5N1 after bird flu case confirmed 

Prime Minister Anthony Albanese says Australia will do “whatever we can” to curb H5N1 bird flu after the first mainland case was confirmed in a seabird, which means the virus has now spread to every continent.

Tests confirmed a migratory brown skua found in ‌Western ‌Australia’s Cape Le Grand National Park had the deadly virus, authorities said on Saturday, and a giant petrel found in the same area was also suspected to be infected.

“This is concerning,” Albanese told reporters in Sydney, adding his government would do “whatever we can to restrict any spread”.

Previously, Australia had been the only continent without a confirmed mainland case, although the virus was detected in late 2025 on Heard Island, a sub-Antarctic territory about 4,100km (2,550 miles) from the mainland.

Agriculture Minister Julie Collins said the virus had not yet been detected in Australia’s poultry or agriculture sector.

“We all knew we couldn’t be bird flu-free forever,” she said.

Human infections remain rare, but the highly pathogenic avian influenza has led to the culling of hundreds of millions of birds globally in recent years, disrupting food supplies and driving up prices.
