First H5 Bird Flu Case Confirmed on SA Metro Beach

Two native birds found dead on separate South Australian beaches have tested positive for the H5 strain of bird flu, marking the first time the virus has been confirmed on a metropolitan beach in the state, according to the CSIRO. The detections involve a greater crested tern found near Robe on the Limestone Coast and another greater crested tern discovered at a beach ramp near the Semaphore Surf Life Saving Club north-west of Adelaide.

Current Detections and Geographic Spread Across Australia

Acting Australian chief veterinary officer Sam Hamilton stated that there are now 20 confirmed or presumed positive detections of H5 bird flu across Australia. “All of these have been individual wild seabirds found in coastal locations,” Dr Hamilton said in a public statement, adding that there remains no evidence of mass mortality events or any detections within the agricultural poultry production system.

South Australia now accounts for seven confirmed cases, while Western Australia records 10, New South Wales holds two, and Queensland confirmed its first case after a dead petrel was found on Moreton Island east of Brisbane. SA Environment Minister Emily Bourke noted that the bird discovered in Robe was located just four kilometres from the site where Australia’s first seabird confirmed with the H5 strain was found. Previous confirmed cases involved migratory birds originating from the sub-Antarctic region, whereas these newer cases involve local bird species.

Poultry Industry Impact and Official Monitoring

State officials continue to monitor the situation closely, emphasizing that commercial flocks remain unaffected. Premier Peter Malinauskas stated prior to the latest confirmations that government policy regarding the virus remains steady. “We still don’t have any evidence of it being anywhere near poultry facilities or the poultry industry, which of course is the biggest risk that we’re keeping a close eye on,” Mr Malinauskas said.

While evidence confirms the virus exists in the native Australian bird population, Premier Malinauskas noted that officials have received advice indicating it cannot be automatically assumed to mean a widespread transmission throughout the population. Authorities stress that the overall risk to human health remains low.
