Australia evacuates Antarctic researchers over bird flu

In late August, the federal environment department removed all twenty four expeditioners from Macquarie Island, located about one thousand five hundred kilometres south-east of Hobart, citing bird flu concerns.

Psychosocial risk cited for removal

The department said evacuation was necessary to avoid the psychosocial impacts of a potential outbreak of the H five strain of bird flu, which has caused mass mortality events among wildlife elsewhere.

“We can't ignore the psychosocial risks of living near potentially large numbers of affected animals.”

Expeditioners dispute the decision

Days after evacuation, multiple researchers sent a letter questioning the rationale, saying the decision undervalued their rigorous preparation, training and resilience and overstated the psychological hazard.

“characterising the potential of witnessing wildlife mortality as an unmanageable psychological hazard overstates the risk”

Researchers say they were prepared

The expeditioners, who arrived in April expecting to stay up to a year, had undergone psychological and medical assessments and specific bird flu training as part of the department's official response plan.

“every individual who signed their contract did so with the full awareness that the risk of the virus arriving was high”

Other countries maintained presence

The letter noted other countries had maintained a presence on sub-Antarctic islands impacted by bird flu, including Crozet, South Georgia and the Falklands, questioning why Australia evacuated without confirmed cases.

“Evacuating a station that currently lacks confirmed cases of bird flu based on predictive distress is not only unnecessary”

Fuel farm poses environmental risk

Expeditioners warned that aging infrastructure on the island, particularly the fuel farm, could pose an environmental hazard without personnel on-site to prevent or detect critical failures or leaks.

“The age and current condition of the station fuel farm presents an unacceptable risk to the environment without personnel on-site”

Bird flu confirmed on the island

After expeditioners returned to Hobart last week aboard the RSV Nuyina, samples confirmed the presence of H five bird flu in an elephant seal and a kelp gull on Macquarie Island.

Department defends decision

The department said the evacuation was based on detailed risk assessment and workplace health and safety legislation, and that the situation would create pressures far beyond usual expectations for personnel.

“the situation on Macquarie Island was likely to create pressures that went far beyond the usual expectations”

Remote monitoring installed, return date unclear

The department installed cameras on the island for remote monitoring and is planning to remove remaining fuel. It remains unclear when expeditioners will be able to return to Macquarie Island.
