According to ABC News, thousands of passengers and crew onboard the vessel from 24 February to 8 March and 8-19 March will be asked to fill in an electronic survey about their trip.
This is part of an Australian police investigation, announced in early April, looking into whether the company violated local biosecurity laws when guests were allowed to disembark in Sydney with flu-like symptoms.

A Carnival Australia spokesperson said: "Princess Cruises is willingly participating in the special Commission of Inquiry established by the New South Wales government and the police investigation announced previously."
