A cluster of COVID-19 cases at Wanniassa School junior campus has increased to 31 as ACT Health investigates a case at Namadgi School Boddington campus in Kambah.
The Wanniassa School community was first told on Sunday about a positive case that visited the junior campus last week.
Since then a cluster of cases has emerged, causing the junior campus and outside of school care to close.
All students, teachers and visitors to the site since Monday, October 25, have been directed to get a COVID-19 test and isolate until they receive the results.
A pop-up COVID-19 testing and vaccination clinic is open at Wanniassa School junior campus on Friday.
Health Minister Rachel Stephen-Smith said ACT Health would decide over the weekend whether the junior campus would reopen on Monday as more test results were returned.
"We know that we'll see household contacts becoming infected as a result of these school-based clusters. So I'll certainly expect to see those [case] numbers to increase over the next few days," Ms Stephen-Smith said.
The case at Namadgi School attended a small satellite program at the offsite Boddington Campus.
It's the fourth school in Tuggeranong this week to discover a COVID-19 case was on campus while unknowingly infectious.
Wanniassa School senior campus, Gordon Primary School and St Anthony's Parish Primary School had positive cases on site but were able to remain open.
Queanbeyan Public School was closed for cleaning and contact tracing on Wednesday and Thursday but was reopened on Friday.
The ACT recorded six new COVID-19 cases in the 24 hours to 8pm on Thursday. A man in his 40s also died from the virus on Thursday after being treated in the intensive care unit.
