South-east Queensland has avoided going into lockdown today, after the state recorded 5 new cases of COVID-19 linked to the same family.

Authorities believe they have tracked down the source.

While there is no lockdown being announced, Premier Annastacia Palaszczuk implored Queenslanders “step up”  to wear a mask indoors, and check-in.

Yesterday it was revealed that a female student at St Thomas More College at Sunnybank in Brisbane had tested positive for COVID-19 and was infectious at the school and community for a number of days.

She also urged people to get vaccinated as there is a “sense or urgency” now.

She said the next 24-48 hours are critical to avoid a lockdown.

Both the Premier and Chief Heath Officer Dr Jeanette Young praised the mother of the girl who got her tested immediately when she complained of a headache.

“We now have all five members of that family positive, across two households,” Dr Young said.

“We know it’s the Delta variant.”

The Premier suggested people in those areas affected write down who has visited their household over the weekend.

It’s believed the father in the family had a visit from someone who was in NSW, and Dr Young believed it was the “likely source” of the outbreak.

It’s also been revealed that the mother, who lives in a separate house, works at Griffith University.
