Three more cruise ships left Sydney Harbour; Ruby Princess remains

Three more cruise ships have left Sydney Harbour overnight following a mass police operation to send vessels affected by the coronavirus crisis home — but the stricken Ruby Princess, which has been linked to 600 cases and 10 deaths, remains off the New South Wales coast.

NSW Police Commissioner Mick Fuller has confirmed there will be a criminal investigation into how thousands of passengers were allowed to disembark from the Ruby Princess cruise ship.

All five other ships left after following a 14-day isolation period except Ruby Princess. All ships returned to their home ports with only crew on board.

Four more Australians have died overnight from COVID-19, taking the national death toll to 34.
