There are 40 active cases in the state, including those in hotel quarantine and no COVID-19 cases in hospitals or ICUs.

Testing figures do not include more than 10,000 results held on Friday due to a malfunction at a testing lab. The last confirmed local infection was on Wednesday when the MCG and Chadstone Shopping Centre were listed as possible acquisition sites for a mystery case of the virus which authorities have yet to confirm the source of. Genomic sequencing has linked the strain to the outbreak in Sydney’s northern beaches.

The source of the Black Rock cluster, which grew to 27 cases, also remains unknown. There are currently 2,000 people isolating or in quarantine for 14 days after being deemed close contacts by visiting or coming in contact with a positive case.
