Cruise captain bars passengers from Hobart

More than 1000 passengers and staff have been stuck on a cruise ship docked at Hobart over coronavirus fears.

About 1400 passengers and staff abroad the MCS Magnifica, which arrived in Tasmania on Saturday, have been told they can't return to the ship if they disembark, an MSC Cruises spokeswoman has told The Mercury.

No one on the ship has the illness but the captain has made the call as a precaution to protect passengers' health.

The ship left Italy in early January before the coronavirus became a global concern.

More than 200 cases of the coronavirus have been confirmed across Australia, including six in Tasmania.

But authorities stress there has been no local transmission on the island state.

Among the two latest cases are a man aged in his 60s who became unwell after arriving in Tasmania following a trip to Canada and the US.

He was not infectious on the flight.

The other case is a woman in her 60s, who has been a close contact of a previous confirmed Tasmanian case who had travelled overseas.

Both the man and woman are in a stable condition and in isolation at Royal Hobart Hospital.
