Suspected H5 Bird Flu detection in Western Australia

19 June 2026

Animal Health Australia (AHA) is aware of a suspected detection of H5 avian influenza in a wild bird in Western Australia, with authorities working to confirm the results.

The virus was detected in a single wild seabird (a skua) found unwell near Esperance on the state’s south coast.Samples have been sent to CSIRO’s Australian Centre for Disease Preparedness for confirmatory testing, with results expected shortly.


There are currently:

  • no reported cases in poultry or livestock 

  • no impact on Australia’s food supply


A second seabird from the same area has been tested, with results pending.

Government agencies are responding quickly. The WA Department of Primary Industries and Regional Development is leading the investigation, with support from the Australian Government. National response arrangements have been activated, with governments and industry working together through established biosecurity frameworks.


Surveillance is also being stepped up in the region to detect any further wildlife cases.

While the detection is being taken seriously, it is still possible that this is a single, isolated detection. Australia has also successfully managed other avian influenza strains in recent years.


There is an official process for communications during outbreaks, but given this is already in the media, we are sharing now.  AHA will continue to monitor the situation closely and will keep members informed as more information becomes available.
