The Border Force even issued a notice instructing the 2,700 passengers that they could travel home in the normal manner, but should self-isolate for 14 days. Health authorities had classed the Ruby Princess as low risk, given it had sailed from Sydney to New Zealand. 'They should not have let us on, and they should not have let us off, and they should not have let us out of the country,' she told The Australian. She said she only learned about the outbreak on the ship when she got to London's Heathrow Airport on Sunday. Several passengers and crew members from the Ruby Princess, including Rona and Michael Dobrin (pictured, left) and Greg Butler (right) have since tested positive for coronavirusĮlisa McCafferty, 48, her husband and her parents were among the 2,700 passengers on the Ruby Princess. The ship, carrying nearly 3,000 passengers, docked in Sydney on March 18, with the holidaymakers pouring into Australia and some even taking domestic flights. In a shocking audio clip played on the Kyle and Jackie O Show on Thursday, a member of staff is heard allegedly telling thousands of passengers they could 'walk off and go home', without the need to self-isolate. There are now 2,725 confirmed cases across Australia, with NSW having 1,219 and seven deaths - the highest number nationwide. It was one of four ships to dock in Sydney in the last week with infected passengers aboard, with authorities fearing the thousands who disembarked may have contributed to a spike in the number of cases of COVID-19 in Australia. The Ovation of the Seas, which docked in Sydney on March 18, has since been linked to 31 cases of COVID-19 in New South Wales alone. Thousands of cruise ship passengers were allegedly told they could 'walk off and go home' with no medical checks, before at least 31 of them were diagnosed with coronavirus.
