Australia’s confirmed bird flu cases continue to increase, with health authorities reporting 52 laboratory-confirmed detections in total. Reporting from Perth and Western Australia states that the latest growth brings the national figure above 50 cases. The update also says that more than a dozen additional cases were confirmed overnight, linked to testing of greater crested terns. These birds have been identified as testing positive for avian influenza, contributing to the rising national case count. The two outlets provide the same core information: the total number of confirmed cases and that a significant portion of the recent increase comes from newly confirmed greater crested tern detections. Both reports are consistent in naming the same species and in describing the overnight rise as involving more than a dozen newly confirmed results. No additional details about geography, timing of earlier cases, or measures taken to contain spread are included in the provided text.
