* NSW recorded nine new locally-acquired COVID-19 cases in the 24 hours to 8pm on Wednesday from a record of more than 60,000 tests.
* Seven of the cases are linked to the 104-strong cluster on the northern beaches, while the sources of the other two infections are under investigation.
* NSW Chief Health Officer Kerry Chant said health authorities are now concerned about the possible emergence of another outbreak in the Sydney CBD. Three cases have been connected to Paragon Hotel Sports Bar at Circular Quay.

* Queensland Chief Health Officer Jeannette Young cast doubt on the NSW road border reopening on January 8, indicating it could be pushed back five days if authorities cannot find the source for the infection of a van driver in western Sydney.
