The state of Victoria in southeastern Australia reported the state's first case of wild birds infected with the H5N1 highly pathogenic avian influenza virus on the 30th. This means that the virus has already been detected in all five states of mainland Australia. The Victorian Department of Agriculture said the H5N1 virus was detected in the body of a large crested tern found near the state's coastal city of Portland, which is about 300 km west of the state's capital Melbourne. Further genetic testing is being carried out by the Australian Centre for Disease Control and Prevention to confirm the test results. Victoria's Chief Veterinary Officer Graham Cook said on the same day that the state has initiated an emergency animal disease response plan to reduce the impact of this highly pathogenic avian influenza virus as much as possible, especially to protect highly threatened species and reduce the risk of poultry farming. Australian Minister of Agriculture, Fisheries and Forestry Julie Collins said on the 29th that local transmission of the H5 avian influenza virus has occurred among large crested terns in South Australia, but the country's poultry farming industry has not yet been affected. In June of this year, the H5N1 highly pathogenic avian influenza virus was first discovered in mainland Australia. According to data released on the official website of the Australian Department of Agriculture, Fisheries and Forestry on the 30th, Australia has detected 28 confirmed cases of H5 avian influenza virus infection in wild seabirds, including 10 in Western Australia, 15 in South Australia, 2 in New South Wales, and 1 in Queensland.
