At least two dozen of the cases were infectious while circulating in the community while seven were in quarantine. Twenty-six of the infections have been linked to previous cases.

The territory now has 233 active cases with 492 patients having recovered. Ten remain in Canberra hospitals, four of them in intensive care and three requiring ventilation.

Authorities say more than 2600 tests were conducted in the 24 hours to Friday evening, while almost 85 per cent of ACT residents have received a first vaccine dose and 58 per cent have been administered with two shots.

Meanwhile, nine patient cases have emerged at a Canberra aged care home after two fully vaccinated workers tested positive.

"What we know is that of the staff at the Calvary Haydon Retirement Community, 100 per cent have received their first dose and 53 per cent are fully vaccinated," Chief Health Officer Kerryn Coleman said.

"In this way, we are very assured that the progress of this outbreak will be very different to what we saw last year when we were all very nervous about aged care facilities."

The initial infection of the two workers happened despite them being double-dosed and wearing appropriate protective equipment.

Across the ACT's aged care sector, about 87 per cent of staff are fully vaccinated while more than 99 per cent have received at least one dose as mandated.

Two virus cases have also been reported in patients sharing a room at Canberra Hospital.

Health Services CEO Dave Peffer said a risk assessment was underway and staff and patients were undergoing testing.

"This sort of incident is not new. It has occurred more than 20 times in our healthcare facilities and we are prepared for it," Mr Peffer said.

ACT Chief Minister Andrew Barr said on Saturday that as regional NSW health services began feeling the burden of caseloads, some COVID patients were being sent to ACT hospitals for treatment, a trend he expected to continue.
