Queensland Deputy Premier Steven Miles said the case, a young child linked to the Indooroopilly Delta cluster, was in home quarantine for their entire infectious period.
The contained new case means restrictions on community sport, gatherings, weddings, funerals, indoor and outdoor events across 11 LGAs will ease from 4pm today.
Easing of restrictions will affect the local government areas of Brisbane, Moreton Bay, Ipswich, Lockyer, Somerset, Logan, Redland, Sunshine Coast, Gold Coast, Noosa and Scenic Rim.
Thirty people will be allowed in homes and public spaces, while weddings and funerals can have up to 100 people.
Community sport can resume with reduced spectators and there will be a 75 per cent capacity for indoor ticketed events and stadiums.
Residents will still need to carry a face mask at all times and wear it when indoors or when they are not able to social distance outside.
High school students will also be required to continue wearing masks in their classrooms for another week.
Queensland Chief Health Officer Jeannette Young said health authorities remain on notice with the ongoing COVID-19 situation in New South Wales.
"Cases are gradually moving north, and it's really important that for another week we maintain some of those restrictions," Dr Young said.
"Masks protect people from getting infected and protect people around someone who is infected from spreading."
Health Minister Yvette D'ath also announced the state had set a COVID-19 vaccination daily record yesterday, administering 20,420 jabs in the past 24 hours.
"We are thrilled so many are coming forward and getting vaccinated … but I do want more people registering for their vaccine," Ms D'ath said.
