It has also been revealed there are 14 cases in the ACT disability care sector. As well, a high-density community housing complex, Condamine Court in Turner, has been listed as an exposure site.

There are three people in hospital in Canberra with COVID-19. Only one is due to coronavirus symptoms although they are stable and not being ventilated.

ACT Chief Minister Andrew Barr says 17 of the new Canberra cases are linked to known cases and two are under investigation.

Mr Barr had previously flagged that Sunday's results could be higher than the eight reported on Saturday due to a reporting change. The cut off time to include numbers changed on Saturday from 9am that day, to 8pm the night before.

"That [19 new cases] is a larger number than yesterday," he said. "It does reflect the situation that we face, that there will still be new cases in the days ahead and what we are striving for is that all of those new cases are not infectious in the community."

The new cases bring the total number of cases in the current ACT outbreak to 121, and 117 of those are linked to known cases or exposures sites. Four cases, in total, remain under investigation.

There are almost 18,000 people in home quarantine across the ACT and more than 320 exposure locations.

About 40 per cent of the ACT's cases are aged 17 years or under, 47 per cent are between 18 and 44 years and 13 per cent are 45 or older.

Of the cases in disability care cluster, four are people with disabilities and the others are care workers and a tradesperson. Twelve of the 14 are ACT residents.

ACT Health Minister Rachel Stephen-Smith says she does not have vaccination status of the people involved.

There is also a wider group affected.

"There are a significant number of disability support workers who are impacted by the current COVID 19 outbreak either as close secondary or casual contacts," the Health Minister said.

The ACT government has known about the disability cluster for a few days and has been working with the sector to assist and protect privacy.

"The team has been working very, very closely with the providers involved and the individuals involved," Ms Stephen-Smith said.

"There are two outbreak management teams that have been formed in accordance with the protocol that exists to specifically focus on outbreaks."

The high density public housing complex Condamine Court is listed as a potential exposure site. It is still being investigated, but officials say a positive case may have visited the complex. There are no known cases living in Condamine Court.

ACT chief health officer Kerryn Coleman says it is regarded as an evolving situation.

"I would like to assure everyone that our approach here will be far more than a health response," she said.

"Our focus will be very much on supporting the tenants and their needs as we work through this.

"We are working closely with a broad range of our partners including Housing ACT and the Community Services Directorate to communicate directly with those affected, as we need to."

Mr Barr has also urged anyone waiting to get testing to do so on Sunday, saying forecast rain would have an impact on pop-up testing centres early next week.

"So our advice today is, if you have been waiting to get a test, wait times are much lower. And today would be a good day to do so," he said.

ACT Health says waiting times have been lower at all testing facilities across the territory this weekend.

Meanwhile, new Covid exposure times have been identified at Woolworths stores at Gungahlin and Belconnen. New exposure sites were listed late on Sunday morning and include post-lockdown exposure times. There are now more than 320 exposure sites in the ACT.

Mr Barr revealed the ACT had now reached 60 per cent of its population with a first dose of a coronavirus vaccination. He said it was encouraging how many Canberrans had come forward to be vaccinated, and he urged people to continue doing so.

Authorities also confirmed there had been a Covid case recorded at the ANU, but said no exposure sites at the university had been identified at this time.

The student is a resident of Warrumbul Lodge and has been in isolation in a self-contained unit for the duration of the ACT lockdown.
