People who have already arrived in Victoria and visited Great Brisbane on or since Saturday 2 January must get tested for COVID-19 as soon as possible, even if they have no symptoms, and quarantine at home or in their accommodation until 6pm on Monday, January 11.

The Greater Brisbane 'hotspot' covers the local government areas of Brisbane City, Moreton Bay, Redland, Ipswich and Logan.

On Friday the Queensland Government ordered a three-day lockdown of the Greater Brisbane area and all Victorians in those areas have been advised to follow the guidance of the Queensland Government and the state government has said Victorian with plans to travel to these areas should cancel them.

In a statement Victorian Chief Health Officer Brett Sutton said Victorians in Greater Brisbane could only enter Victoria if granted an exemption.

"Exemptions are limited and granted only in special cases," he said.

"National Cabinet has declared Greater Brisbane a national hotspot after the discovery of a UK variant of COVID-19 in a cleaner at a Brisbane quarantine hotel.

"We can confirm that a woman who tested positive to coronavirus in Queensland yesterday had been in hotel quarantine in Victoria.

"The woman arrived in Victoria from the UK on December 26 with symptoms and was immediately tested for coronavirus. She returned a positive result on December 27. Genomic test results later indicated that this woman had the B.1.1.7 lineage of the virus, that is currently predominantly found in the UK.

"The woman completed 10 days of isolation in hotel quarantine and was released from quarantine on 5 January in line with current national guidelines at the time."

The woman had been symptom-free for three days prior to medical clearance and release, which was consistent with national protocols.

"People who recover from coronavirus can continue to 'shed' the virus for several weeks, although they are not considered infectious," Mr Sutton said.

"In response to concerns about the UK variant, new national protocols were introduced that require hotel quarantine cases who test positive with the UK variant and recover to stay in isolation for 14 days and complete an exit test. These were immediately implemented in Victoria."

Victoria recorded one new case of coronavirus since yesterday in a member of an international flight crew in hotel quarantine.

According to the state government the new hotel quarantine case is in a woman aged in her 30s.

Victoria has recorded no new locally acquired cases of coronavirus and the number of active cases in the state is now 40, made up of 28 locally acquired cases which is no change since Friday and 12 cases in hotel quarantine, an increase of one in the past 24 hours.

On Friday there were 28,337 tests were processed.
