Kangaroo Island grapples with H5N1 outbreak as mass bird deaths spark vaccination debate

Authorities have confirmed three mass mortality events involving over 1,000 crested terns on remote South Australian islands, including two incidents off Kangaroo Island, and are investigating a little penguin found at D’Estrees Bay for H5N1 infection. Mayor Michael Pengilly described the situation as distressing and noted waste-depot facilities and eco-bins are being used to manage carcasses. Environment Minister Emily Bourke said testing is underway and that a prior site at Baudin Rocks may have seen over 500 deaths.

Local penguin tour operator Renee Daniell, whose business relies on a growing colony of about 200 birds, expressed anxiety and openness to vaccinating the species. Premier Peter Malinauskas confirmed that a vaccination scheme is being considered, but emphasized the need for regulatory approval and the logistical challenges of administering doses to wild birds. Volunteer Stephen Hedges on nearby Granite Island also warned of potential impacts on his penguin population.
