NSW reports 127 new cases, including three cruise ship crew members

New South Wales has reported 127 new coronavirus cases overnight, including three crew members who were medically evacuated from a luxury cruise ship off Sydney's coast.

NSW Health said there are 1918 confirmed cases of COVID-19 in the state.

Of this number, 26 are in intensive care units, with 13 of the cases requiring ventilators at this stage.

Cruise ship passengers continue to make up the state's highest confirmed number of cases.

There are 189 cases from the Ruby Princess, 66 cases from the Ovation of the Seas, 26 cases from the Voyager of the Seas and two new cases from the Celebrity Solstice.

Yesterday a team of one doctor and four paramedics transferred three crew members from the Voyager of the Seas who are thought to have the virus. They have been moved to RPA Hospital.

"Approximately 70 swabs from unwell crew members on the Voyager of the Seas have been tested for COVID-10. Four crew members have tested positive for COVID-10," NSW Health said in a statement.

"NSW Health is working with the cruise line (Royal Caribbean) to ensure infection control, isolation of all crew and care of unwell people aboard the ship."

Meanwhile, three cases of COVID-19 have been confirmed at Tyndale Christian School in Blacktown.

The cases involve two students and a staff member.

The school is closed today and tomorrow for contract tracing and cleaning.

Three more cases of the virus have been confirmed at Rose of Sharon childcare, with a childcare worker and two children contracting COVID-19.

"All children have been isolated as close contacts," NSW Health said.
