A ship off the South West coast — which is carrying eight COVID-positive crew and was set to dock in Bunbury on Thursday — has been asked to drop anchor and wait at sea. WA Health is monitoring the vessel and has made contact with the oil carrier MV Ballard, confirming today it will not dock as originally scheduled. Of the 23 crew aboard the ship, which last docked at Manila, eight have tested positive for the virus and are isolating in their cabins. It comes as two new cases linked to the cluster at a Kemerton lithium plant were recorded among the State’s 13 new positive tests on Tuesday. Eight of the 13 cases are linked to a known cluster. Five more remain under investigation. The total number of cases linked to Albemarle’s plant now stands at 23 with only one new case recorded on Monday. The five new mystery cases prompted a fresh plea from authorities for anyone in the Perth, Peel, Wheatbelt and South West — “particularly the greater Bunbury area” — to immediately get tested and isolate if they experience any COVID-like symptoms. “This applies to anyone symptomatic — even if you have not visited a listed exposure site,” WA Health said. Locations across Perth, including Northbridge and CBD nightspots, have been added to the list of confirmed exposure sites but no new South West locations have been posted.
