Queensland health authorities are cautiously optimistic the current lockdown on the state's south-east will be able to lift on Sunday as planned, dependent on testing and COVID-19 case numbers.
The state recorded 16 new coronavirus cases yesterday. They were all linked to the west Brisbane cluster and only four of those cases had been out in the community while infectious.
Eight of yesterday's cases are aged 19 or under, meaning 52 of the cluster's 79 cases are children or teenagers. Meaning 52 of the cluster's 79 cases are children or teenagers.

The state also set a new testing record with more than 52,000 tests carried out in the previous 24 hour period.
Queensland Chief Health Officer Dr Jeannette Young said while she was "hopeful" lockdown restrictions could lift in Queensland's 11 south-eastern LGAs on Sunday, there was still work to do.
"We've still got a while to go," she said.
"We still need to do that 50,000-plus tests per day, we still need people, over 7000 of them, to remain in quarantine and not leave for any reason unless it is an absolute, dire emergency."
Queensland Health confirmed exposure sites including a school playing field in East Brisbane and a junior football game at The Gap.
