Genomics testing has confirmed the hotel quarantine worker who tested positive to COVID-19 on Wednesday has the UK variant of the virus.

Victorian authorities are still working to establish how the highly infectious virus strain was transmitted to the worker, who is a 26-year-old man from Noble Park.

Sixteen of the man's close contacts have tested negative for COVID-19. Test results from a 17^th close contact are still being processed.

Premier Daniel Andrews said a strong testing turnout in the previous 24-hours, which had yet to detect any new community transmission, were "the best outcomes we could hope for".

He thanked Victorians for the part they were playing in keeping the community safe, but said it was not over yet.

Mr Andrews reiterated calls for Victorians to get tested for COVID-19 at the earliest sign of symptoms.

The press conference ended as leaders of Australian state, territory and federal governments headed into a national cabinet meeting.

The meeting is expected to cover topics such as COVID-19 vaccines, caps on returning international travellers, and the potential for more hotel quarantine arrangements in regional locations.
