Red alert for Brisbane and Sunshine Coast while lockdown lifts in Sydney

More than two million Queenslanders will be able to come out of lockdown today.

While the Premier added she was "absolutely thrilled" that there had been no new community cases, there had been four worldwide cases identified in quarantine.

"The compliance has been exemplary so thank you to the community of southeast Queensland and those areas that are impacted for what you've done to work with us", he said.

Masks will have to keep being worn in indoor places, including shopping centres and supermarkets, gyms, workplaces, places of worship, libraries, taxis and ride shares.

Queensland chief health officer Dr Jeanette Young says a man gave the United Kingdom variant of COVID-19 to a hotel cleaner who sent Brisbane into lockdown.

This could include walking the dog, while travelling in your private vehicle or going out for "strenuous exercise".

Offences include leaving home without an exempt objective, having too many visitors and the refusal to wear a mask. Measures included mandating face masks for indoor public areas and reducing patron limits on bars, restaurants and other venues.

Health authorities urged residents living in Maleny to watch for symptoms after a Victorian woman - also carrying the United Kingdom variant of coronavirus - travelled there to visit her parents.

The highly contagious United Kingdom variant has potentially been active in the community since January 2 but no locally acquired cases have yet been detected.

Chief Health Officer Dr Jeannette Young says the man has been in quarantine since 7 January and additional contact tracing is underway.

Two of those people had travelled to the United Kingdom, but Dr Young said it was too early to know if they had the more contagious strain of the virus.

Additionally, retail and indoor hospitality venues will revert to the one-person-per-four-square-metre density rule (smaller venues up to 200 square metres can have one person per two square metres - up to a maximum of 50 people). Gatherings of 20 people will be allowed in public areas and in homes, while weddings and funerals will be capped at 100 people. Other outdoor stadiums (with Covid-safe plans) will operate at 50-per-cent capacity.

This doesn't mean there won't be more cases, but Dr Young says if any of those contacts do come down with the virus, they're in quarantine now and won't pose a danger to the wider community.

"We are also asking those people to come forward for testing regardless of whether they have symptoms or not", she said.

Premier Annastacia Palaszczuk announced earlier that Queensland has recorded zero new cases overnight.

People from Greater Brisbane will now be able to travel to the ACT, the Northern Territory and Tasmania without restrictions after the state and territories revoked their classification of the region as a COVID-19 hotspot on Monday.

Chamber of Commerce and Industry Queensland's Amanda Rohan said the lockdown and the new rules were a setback for businesses during the crucial school holiday trading period.
