Twenty-one crew are quarantining aboard a cargo vessel in northern Tasmania after being identified as primary contacts of a Victorian dock worker who tested positive to COVID-19.
The crew of the African Rook have returned negative tests but must remain on the ship until at least October 1, when their 14 days of quarantine elapses.
"There is no risk to the Tasmanian community as the crew remained on board at all times and had no contact with members of the public," deputy state public health director Julie Graham said on Monday.
All 21 crew were classified as primary close contacts of a Victorian stevedore who worked on the vessel in Geelong on September 17 and subsequently tested positive.
They were tested on board on Saturday and will be retested prior to the vessel being allowed to continue its journey.
"Confirmation of the crew's status was received on 20 September after the vessel had departed Geelong and as it reached Tasmanian port limits," Dr Graham said.
The vessel, which was scheduled to unload cargo at Devonport, was diverted to Bell Bay on Saturday and is berthed in a secure port zone.
It comes after the Spirit of Tasmania ferries were forced to suspend sailings across Bass Strait when a contractor with operator TT-Line tested positive in Melbourne.
Services were halted on Friday night but were given the all-clear to resume on Sunday evening after close contacts tested negative.
