Testing at CSIRO´s Australian Centre for Disease Preparedness (ACDP) has confirmed a positive H5 bird flu result for two greater crested terns found in Robe and Semaphore, South Australia.

There have now been 20 confirmed or presumed positive detections of H5 bird flu in Australia.

All of these have been individual wild seabirds found in coastal locations.

There remains no evidence of any mass mortality events and there are no detections in poultry or in our agricultural production system.

The risk to human health remains low.
