Local environmentalists and biosecurity officials are expressing growing concern over the rapid spread of H5 bird flu in South Australia, following a series of distressing discoveries along the coastline.

Authorities are currently investigating a major bird mortality event after more than 80 sick and dead birds were uncovered on Baudin Rocks, located roughly five kilometres off the coast of Cape Jaffa. Test results from the site are expected in the coming days as officials work to confirm the cause of the deaths.

A Shift to Local Transmission

The discovery comes on the heels of confirmation that local transmission of the virus has occurred among native wild birds in South Australia for the first time. Species such as silver gulls and greater crested terns are among those severely affected.

BirdLife Australia senior advisor Sean Dooley warned that the country is entering a new, more serious stage of the outbreak. Rather than isolated infections, experts are now seeing the virus pass between native populations. Because these species are abundant along the coastline, officials anticipate further outbreaks as the birds move around regional waterways.

Community Distress on Local Beaches

For dedicated citizen scientists monitoring coastal health, the unfolding situation has been deeply heartbreaking. Local volunteers at Glenelg Beach, who spent months tracking the impact of recent toxic algal blooms, say finding birds suffering from viral symptoms is particularly distressing.

Volunteers have been actively searching shores and reporting suspected cases, including infected silver gulls, directly to the Department of Primary Industries and Regions in an effort to track the spread in real time.

National Case Count and Sector Readiness

Nationwide, confirmed H5 cases have reached 54, with South Australia bearing the brunt of the surge with 40 confirmed instances. Western Australia has recorded 10 cases, New South Wales two, and Queensland and Victoria one case each.

Importantly, biosecurity authorities confirmed there have been no detected cases in commercial poultry farms or livestock. Federal Health Minister Mark Butler stated that while officials remain concerned about the rising wild bird numbers, extensive preparation and talks with the poultry industry have been underway for months to help mitigate potential agricultural impacts.
