World’s largest bird flu vaccination campaign on Phillip Island

THE historic wildlife rescue operation now underway on Phillip Island marks the largest wild bird vaccination effort ever attempted worldwide with the ambitious, high-stakes program aiming to protect up to 5,000 of Victoria’s iconic Little Penguins from a devastating strain of avian influenza.

Highlighting the urgency of the environmental crisis during a recent tour of the Bass Coast Minister for Regional Development Michaela Settle welcomed the groundbreaking initiative.

"The death of even one Little Penguin is very sad," Minister Settle said, emphasising the profound ecological and economic impact the loss would have on the region.

The unprecedented operation required strict federal clearance and rigorous environmental assessments before wildlife teams could safely hit the ground.

Due to the experimental nature of administering avian influenza vaccines to wild populations, state authorities worked closely with national biosecurity officials to secure the necessary exemptions.

“We needed the Federal Government to approve the vaccinations before we could begin,” Minister Settle explained. “We got that approval and began the vaccinations as soon as we possibly could.”

The rollout has presented immense logistical hurdles for field officers and veterinarians.

Teams must carefully locate the penguins, microchip each individual for tracking, and manually administer the vaccine via injection. Achieving full immunity requires a strict two-dose schedule, presenting a massive challenge when dealing with wild animals.

Fortunately, the unique homing behaviour of Little Penguins provided researchers with a distinct tactical advantage. “Vaccinations require two doses,” Minister Settle said. “One of the reasons we can work successfully with Little Penguins is that they tend to go back to the same burrow at night. The program began with an initial vaccination and a tag.”

Targeting the birds within their known nesting boxes and burrows under the cover of darkness, handlers will be able to reliably able to locate the same individuals weeks later to deliver the crucial booster shot.

While the immediate frontline focus remains on the world-famous wild colonies at Phillip Island and St Kilda, federal and state authorities are taking no chances with the highly contagious virus.

Protective measures are simultaneously being extended to vulnerable captive bird populations housed across various Victorian zoos to prevent further spread.

Minister Settle assured the public that the campaign is backed by rigorous scientific testing and international veterinary data. “The community should have confidence that we are running the vaccination program,” she said.

To safeguard the local commercial poultry sector and keep everyday eggs affordable, Minister Settle has introduced temporary housing mandates. Free-range poultry farms across high-risk zones must now keep their flocks strictly indoors to eliminate physical contact with infected wild birds.

This unprecedented intervention has highlighted the severe threat avian influenza poses to both commercial food production and vulnerable native ecology. Victoria's swift action aims to build a wall of immunity around its most famous avian residents.

As field teams brave the elements to secure the penguin colony, conservationists worldwide are watching closely. The success of this mammoth task could rewrite the playbook for saving endangered seabirds from global disease outbreaks.
