The Greater Brisbane lockdown will end at 12pm on Thursday after only one new case of community transmission was recorded in Queensland.

The single case is linked to an existing cluster and has been in quarantine during their infectious period.

Premier Annastacia Palaszczuk said the key factors in relaxing the stay-at-home restrictions before Easter were high testing rates and no unlinked cases in the community.

"If you have plans, the lockdown is lifted from 12 noon today," she said.

"Easter is good to go."

Several restrictions remain in place for the whole state for the next 14 days.

Queenslanders must wear a mask when indoors except when eating and drinking and must be seated in restaurants and pubs.

Gatherings in homes are capped at 30 people and visits to hospitals, aged care and disability facilities and prisons are not allowed, apart from end-of-life situations.

Queensland's Chief Health Officer Jeannette Young described Thursday's new case as "perfect".

She confirmed it was another guest at a Byron Bay hen's party who tested negative on Monday before returning a positive result on Wednesday.

She said testing rates during the lockdown had been "astronomical", with more than 34,000 tests in the past day.

"We can be reasonably confident we don't have other trains of transmission ... in the community," Dr Young said.

More than two million Queenslanders will be free of the stay-at-home restrictions that came into force on Monday, as the state tried to contain two separate clusters linked to healthcare workers.

The lockdown was due to end at 5pm on Thursday, but has been brought forward to midday.

Ms Palaszczuk said the new deadline would help manage traffic as Queenslanders departed for the Easter break.

"Please look out for each other on the roads, take your time," she said.

The Princess Alexandra Hospital, which is linked separately to the state's two clusters, is at the centre of efforts to ensure the virus does not spread further.

Any workers who set foot inside the ward from March 23 to 26 have also been ordered into two weeks of quarantine, even if they weren't directly involved in patient care.

The state's cases include a nurse from the hospital who travelled to Byron Bay with her sister without realising she was sick or that she had infected her sibling.

During a weekend away for a hens' night, they infected others in their group.

A man who sat near them at the town's Byron Beach Hotel has also tested positive, sparking health alerts in NSW.

The virus scare in Byron Bay prompted the cancellation of the tourist town's Bluesfest music festival and the reintroduction of restrictions in northern NSW.

Queensland recorded a further nine cases in hotel quarantine.
