The update informs of 17 passengers and one crew member diagnosed in NSW, and 8 passengers diagnosed interstate (as of 8 pm Saturday).

This follows an official announcement by Princess Cruises Friday, informing of three passengers and one crew.

The Ruby Princess cruise to New Zealand left Sydney on 8 March and returned to Sydney and docked Thursday morning.

There were a total of 2,647 passengers on board who disembarked Thursday. They were all advised to self-isolate at home or in their accommodation for a period of 14 days as part of the management of returned travellers, in accordance with the Public Health Order for quarantine that is in place in New South Wales.

In light of the above, as of midnight March 22, NSW Health will go even further beyond the National Protocol and its current own State protocols and will hold all cruise ships in port until any patients highlighted as having respiratory issues are tested for COVID-19.
