The Covid-19-stricken Ruby Princess cruise ship has finally docked in New South Wales - where sick crew are being treated onboard and the more serious cases transferred to hospital. About 200 of the 1,400 crew are said to be showing symptoms of coronavirus. The Ruby Princess cruise ship is Australia's single biggest source of Covid-19 with more than 600 cases linked to the ship. It also accounts for about one sixth of Australia's Covid-19 death toll - including a New Zealand-born woman. It is now the subject of a criminal investigation and a lawsuit - with conflicting reports about whether passengers who were likely to be ill were knowingly allowed to disembark in Sydney. Di Walker and her husband Robert, from Hawke's Bay, were in a tour group of 10. Six of that group have since tested positive for the virus. Di says she was never told of any issue onboard the ship - not even a rumour of illness and certainly had no idea she was at risk of Covid 19.
