Breaking: H5 bird flu strain detected in Australian seabird for first time

The H5 strain of bird flu has been detected in an Australian seabird for the first time.

Previous confirmed cases have involved migratory birds from the sub-Antarctic region.

Agriculture Minister Julie Collins says CSIRO lab testing has confirmed the deadly strain in a greater crested tern found in Robe in South Australia's Limestone Coast.

There have also been two further confirmed cases in South Australia and one in Western Australia, bringing the total number of detections to 12.

Ms Collins says there is still no evidence of mass mortality among wildlife and no evidence of any spread to agricultural settings.
