Greater Brisbane will enter a hard lockdown from 6pm on Friday after a cleaner at a quarantine hotel was diagnosed with the highly contagious UK variant of COVID-19.
Residents in the council areas of Brisbane, Logan, Ipswich, Moreton Bay and Redlands will be required to stay at home until 6pm Monday except for essential work, exercise, essential shopping and to access healthcare.
Masks will also be mandated for people leaving home in the Greater Brisbane area.
The cleaner is Australia's first case of the more infectious strain of the coronavirus outside of quarantining returned overseas travellers.
Chief Medical Officer Paul Kelly said the situation in Queensland was concerning.
"We do know that we've had cases of the UK variant in our hotel quarantine system," he told ABC RN on Friday.
"And we do know sometimes with a very complex system which relies on humans, mistakes can happen. That apparently is the case here."
The hotel cleaner's infection ended almost four months of zero locally acquired cases in Queensland.
She visited several locations while potentially infectious and contact tracers are tracking her movements.
The woman travelled on a train from Altandi station to Roma Street station at 7am on January 2, then returned on the 4pm service the same day.
She also visited Woolworths at the Calamvale Central Shopping Centre from 11am to 12pm on Sunday 3 January.
She was at Coles in Sunnybank Hills for 30 minutes from 7.30am on Tuesday 5 January and a newsagent at Sunnybank Hills Shopping Town from 8am to 8.15am on the same day.
Residents of Algester, Sunnybank Hills and Calamvale who have symptoms of the infection are especially urged to get tested as soon as possible.
