Biosecurity Queensland has confirmed that initial laboratory samples taken from a deceased petrel washed up on Moreton Island (Mulgumpin) were positive for H5N1 as Queensland became Australia’s fourth state to confirm a case of the highly pathogenic H5N1 avian influenza (bird flu). The samples were later confirmed to be positive for H5N1 by the CSIRO.

When the disease arrived in ​June 2026, Australia was the final continent to confirm a mainland case ​of H5N1, although it had been detected in ⁠late 2025 on the sub-Antarctic territory of Heard ​Island, about 4,100 km (2,600 miles) from continental Australia.

Confirmed cases also appear to have arrived with seabirds travelling from the south. A second influx of the virus may come from the north with migratory shorebirds arriving on East Asian Australasian Flyway from mid-July-August from Siberia (via China, Japan and the Republic of Korea).

Mainly carried by birds, the virus has been known to jump to other species, such as marine mammals. Currently there have been no detections of the disease in native birds or poultry in Queensland, and no evidence of large-scale animal deaths.

Our focus remains on early detection, reducing biosecurity risks and protecting vulnerable species. To keep K’gari and her native animals safe, we need your help. If you see sick or dead wild birds or wildlife, remember:

• AVOID CONTACT: Do not touch or handle sick/dead animals (unless trained with appropriate PPE).
• RECORD: Note the location, date, time, and how many birds are affected. Take photos or videos from a safe distance.
• REPORT: Call the 24-hour Emergency Animal Disease Hotline on 1800 675 888 (24/7).
