Western Australia has recorded one new COVID-19 case but the infected crew of a ship off the state's coast are continuing to recover.
The new case is a man in his 30s who returned to Perth from Dubai. He is in hotel quarantine.
WA now has 16 active cases, including 14 among crew of the Patricia Oldendorff bulk carrier anchored off Port Hedland.
Three previously infected crew are no longer considered to be a risk of spreading the disease, WA Health has confirmed.
The vessel, carrying 20 Filipino nationals and the captain, arrived from Manila on September 16 and is anchored eight nautical miles off WA's northwest coast.
Nine people remain on the ship as essential crew and there are also a dozen crew members in quarantine at the fenced-off Hedland Hotel.
All but four returned positive tests.
None of the crew are seriously unwell and WA Health is confident the ship will have enough healthy crew to set sail in the next week.
Meanwhile, a cargo ship docked at Fremantle Port is expected to depart later on Monday after a crew member tested negative to COVID-19.
The crew member aboard the Kota Legit vessel was tested after it emerged they had been unwell while the ship was at sea.
"The crew member is not ill and no other crew members onboard the ship have been reported with illness," WA Health said.
"The ship can recommence activities and depart Fremantle to travel to its next port."
The ship arrived in Fremantle after a seven-day voyage from Port Klang in Malaysia. It's believed to have been in China and Singapore before that.
