The Covid-19 threat is continuing to increase in Queensland again, with a major Brisbane high school closed for deep cleaning.
Indooroopilly State High School sent a late-night email to parents advising them the campus would not be open on Friday.
Acting executive principal Derek Weeks said a "person associated with" the school community had tested positive to the virus.
"As a result, our school will be closed effective immediately (on) July 30 for 48 hours to allow for Queensland Health to perform this contact tracing and, as an extra precaution, I have arranged for specialist cleaners to perform a deep clean," he wrote.
"The health, safety and welfare of your children, our students, continues to be my number one focus."
