Queensland has recorded one new locally acquired case of COVID-19, but the teenager was already in home quarantine and authorities believe the outbreak is under control.
Chief Health Officer Jeannette Young says the new case emerged on Tuesday after 13,396 tests in the previous 24 hours.
The case is a 15-year-old girl who is a student at the Saint Thomas More College in Sunnybank, where three other students and some of their family members have also tested positive for COVID-19.
Dr Young is confident the outbreak in southern Brisbane is under control because the new case was not infectious while in the community.
"So it's not surprising, and they'll be then managed and their family, of course, so this is very good news," Dr Young told reporters on Tuesday.
"It looks like, due to the fantastic contact tracing work and the superb work done by that family, that we've managed to get this outbreak controlled so quickly.
"But we know that we could have another case come into Queensland at any time, so could everyone please continue to do that work and come forward and get tested, with only the most minor symptoms, any symptoms at all, just come forward and get tested.
"It doesn't matter where you live in the state, because this could pop up anywhere."

Meanwhile, police say Queensland's hard border with most of NSW could remain in place until the state hits its vaccination coverage targets of 70 per cent or 80 per cent.
The news comes as Queensland confirms eligibility for support packages for businesses in its border communities will be extended to align with the NSW lockdown.
"Businesses along our border have suffered because of the actions and inactions of the New South Wales government, resulting in outbreak, lockdown, and the border restrictions that necessarily follow to protect Queenslanders," state treasurer Cameron Dick told parliament on Tuesday.
The support is part of a $600 million package agreed with the Commonwealth, and Mr Dick said the state would also invest "directly" through contributions including an extra $1 million to Gold Coast City Council's voucher scheme.
The Queensland border has been shut to NSW for almost two months due to the ongoing COVID-19 outbreak in that state, which grew to 14,633 active local cases by Monday.
Queensland is granting special exemptions for residents of NSW border communities as far south as the Clarence Valley and as far west as Moree Plains local government areas to enter.
Only residents in those areas who have received one vaccine dose and who cannot work or study from home, need to do essential shopping or care for vulnerable people are allowed to enter Queensland.
Deputy Police Commissioner Steve Gollschewski says there is no clear end date for when border restrictions will ease.
"We were planning a little bit open-ended," he told ABC radio on Tuesday.
"We are obviously dealing with what the here and now is and adjusting to the changes as they come."
