The ACT has recorded 30 new cases of COVID-19 to 8pm Thursday.
Twelve of the new cases were in quarantine for their entire infectious period, 14 spent some time in the community.
Nineteen cases have been linked to previous cases and the remainder have not yet been linked.
There are eight people with COVID-19 in hospital in the ACT. One person is in intensive care and requires ventilation. The youngest patient in hospital is in their 30s and the oldest is in their 70s.
Chief Minister Andrew Barr said the case number was "simply too high" but it was too early to say if it was a trend.
Mr Barr said there would be more compliance activity around the ACT border to prevent people moving around during the school holidays.
"Yes the Defence Force will be involved and yes, there will be boots on the ground," he said.
Chief Health Officer Kerryn Coleman said the higher case number was not necessarily an indication that cases were trending upwards.
"The number of cases we're seeing depends on very much our testing every day. So if we're doing a lot of people who are coming to the day-seven tests as part of their quarantine or the day-two or -three test of an exposure site, we might expect to see a glut of cases coming through," she said.
"This is just part of the ebbs and flows, it's very difficult to link it to any event or cluster."
Dr Coleman said the total number of cases for the current outbreak stood at 586. A total of 341 people have recovered from COVID-19 after a further 26 recovered in the 24 hours to 8pm Thursday.
Two of the new cases have been linked to the Busy Bees childcare centre and were household contacts of previous cases.
The Department of Education, Skills and Employment building listed as exposure site on September 10.
Dr Coleman said the computer science and information technology building and Birch Building at the Australian National University have also been identified as COVID-19 exposure sites and will be listed on the public exposure locations website today.
A student at the University of Canberra has also reportedly tested positive.
Health Minister Rachel Stephen-Smith said 98.2 per cent of aged care staff have had one dose of a vaccine and 83 per cent have had both doses of a vaccine. On Friday it became mandatory for all aged care workers to be vaccinated.
Ms Stephen-Smith said disability care cluster was at 30 cases with 13 of these being workers, including two NSW cases, and six people are clients of disability services. The remaining people were one tradesperson and ten household contacts of workers.
Meanwhile there have been 17 new cases reported in southern NSW to 8pm Thursday, including five cases in Yass, four in Batemans Bay, three in Queanbeyan, two in Googong and three in Goulburn.
