Chief Health Officer Jeannette Young says there’s a low risk of spread because of those arrangements.
However one of the newly positive students was infectious for a very short period of time before entering home isolation, so there are additional exposure sites that will be listed.
“But I’m fairly confident that cluster is in hand,” Dr Young told reporters on Monday.
Because of that confidence, she’s immediately lifted visitor restrictions on hospitals, aged care, residential disability care and prisons in southern Brisbane.
There were 14,506 tests and 15,378 vaccines delivered by Queensland Health in the past 24 hours.
That means 56.39 per cent of eligible Queenslanders have had one vaccine dose and 38.08 per cent are fully vaccinated.
There were no new local cases recorded on Sunday but there were five, all linked to the Sunnybank cluster, on Saturday.
All five were family members of the 13-year-old girl who attends St Thomas More College. The family lives across two different households.
It’s believed the girl was infected by a visitor from NSW. She was exposed when she and her siblings saw their father on Father’s Day and then returned to their mother’s home.
The man, who entered Queensland with two others on September 5, has since returned to NSW. All three men are believed to have crossed the border with the correct passes but police are investigating.
The Queensland-NSW border bubble arrangements resumed at 1am on Monday, allowing essential workers and students in a select number of local government areas, including Tweed Shire, to cross the border.
But they’re only allowed to cross for very specific reasons, including for essential work that can’t be done from home, for school, healthcare and caring for vulnerable people. And they must have had at least one dose of a vaccine.
