Queensland's current Covid-19 outbreak added 10 cases at Friday's Covid update.
Deputy Premier Steven Miles said the new cases were all linked to the original Indooroopilly cluster.
The new cases bring the number of cases in the current outbreak to 89.
Five cases are household contacts of Ironside State School cases.
Three are household contacts of Indooroopilly State High School and two are household contacts of Brisbane Boys' Grammar School cases.
Eight of the cases were not infectious in the community.
Two further cases were infectious in the community for one day but during the lockdown period.
'We need to continue to see low case numbers all linked, declining infectious days in the community and a high rate of testing and if we can keep that up, then we will be able to begin to ease these restrictions,' Deputy Premier Steven Miles said.
Chief health officer Dr Jeannette Young said: 'Hopefully, and I genuinely am hopeful that we will be able to lift [lockdown] this on Sunday.'
The new cases came as some Brisbane residents joined long queues for the opening of an acclaimed pastry retailer in South Brisbane.
