Six passengers quarantined at the Centre for National Resilience in Bullsbrook, north-east of Perth, have been cleared to return home after completing one of Australia's strictest recent quarantine operations. The group had been exposed to a hantavirus outbreak linked to the expedition cruise ship MV Hondius.
The travellers — five Australians and one New Zealander — arrived at the quarantine facility on May 15 after being evacuated from the cruise ship, which was affected by an outbreak of the rare Andes hantavirus strain. Health authorities initially planned a shorter quarantine period but later extended it to June 23 after additional infections were detected among other passengers overseas.
The outbreak aboard the ship resulted in multiple infections and three deaths internationally, prompting an extensive global public health response. The World Health Organization identified the outbreak as involving the Andes strain of hantavirus, a rare form capable of limited person-to-person transmission.
Australian health authorities adopted a cautious approach, requiring the six travellers to complete the full 42-day incubation period in quarantine. Throughout their stay, the passengers underwent repeated testing and medical monitoring, with all tests returning negative results.
Federal Health Minister Mark Butler previously described the operation as one of the strongest responses undertaken globally to the outbreak. The Bullsbrook facility, originally established during the COVID-19 pandemic, was used to ensure there was no risk of community transmission.
Australia's Chief Medical Officer Michael Kidd formally cleared the passengers for travel after the quarantine period ended. The group was transported to Perth Airport and allowed to return home without any further isolation requirements. Health officials confirmed no additional monitoring would be necessary.
The release marks the conclusion of Australia's direct quarantine response to the cruise ship outbreak. Similar monitoring programs were conducted in other countries, including the United States, where exposed passengers also completed 42-day quarantine periods before being released.
Health authorities say the successful completion of quarantine without any infections among the Australian group demonstrates the effectiveness of the country's biosecurity and public health systems. The operation was closely watched internationally because of the rarity of the virus and concerns about potential human-to-human transmission.
