Confirmed or presumed positive cases of H5N1 bird flu in Australia reached 203 on Saturday, marking a 290 percent increase since the end of July.
South Australia recorded 147 cases, including 28 new detections in wild seabirds, while Victoria reported 43 cases, prompting new indoor housing requirements for poultry.
The Victorian government mandated that poultry producers with at least 50 birds must keep them indoors for 14 days to prevent the spread of the deadly strain.
