The CSIRO’s Australian Centre for Disease Preparedness (ACDP) has confirmed positive test results for H5 bird flu in samples from 2 wild birds since yesterday’s update.

The new confirmed cases involve a greater crested tern and a silver gull, both from Port MacDonnell on the Limestone Coast.

All were previously reported as suspect detections and have now returned positive results for H5 bird flu following testing at the ACDP in Geelong, Victoria.

There have now been 297 confirmed positive H5 bird flu detections in South Australia.

A further 4 suspect cases of H5 bird flu in South Australia have been detected since the last update, bringing the current number of suspect cases to 14. These include:
