A criminal investigation will be launched to into how the cruise line operator Carnival Australia was allowed to disembark the Ruby Princess in Sydney and spread coronavirus.
"The only way I can get to the bottom of whether our national biosecurity laws and our state laws were broken is through a criminal investigation," NSW Police Commissioner Mick Fuller said on Sunday.
He said there was clear evidence COVID-19 has come off the Ruby Princess and at least 10 passengers have died in Australia because of it.
The investigation will cover the actions of the port authority, ambulance, police, the NSW Health deportment and Carnival Australia.
Detective Chief Inspector Jason Dickinson of homicide will lead the investigation and the coroner will be notified.
