Geelong’s CSIRO lab is conducting further tests on a wildbird with suspected H5 bird flu.
The greater crested tern was reported by a community member in Portland this week.
Agriculture Victoria has sent samples to the Australian Centre for Disease Preparedness in Geelong.
There is now one confirmed case and one suspected case in the state.
There are 33 confirmed cases across Australia.
Chief Veterinary Officer Dr Graeme Cook said it highlighted the importance of early reporting of any sick or dead wildlife.
“We have been preparing for the arrival of H5 bird flu, and we’re now using those plans to support surveillance, testing and response activities across the state,” Dr Cook said.
“We ask Victorians to avoid contact with sick or dead wildlife, record what they see and report it. Early reporting gives us the best chance to reduce the impacts of the disease.”
Federal Environment Minister Murray Watt said there was a low risk for humans, but the country was also prepared.
“It is reasonable to expect that we are going to see more (cases) now that bird flu has arrived on Australian shores,” he said.
“You may have seen this week as well, that it has been confirmed that there has been local transmission of bird flu.”
Anyone who sees any sick or dead wildlife is being urged to call the Emergency Animal Disease Hotline on 1800 675 888.
