There were 725 new COVID-19 infections reported in the ACT on Sunday, which included 376 positive PCR test notifications and 349 positive rapid antigen test results.

No deaths were reported on Sunday.

There were 58 people in hospital and three people in intensive care at 8pm on Saturday, however no one was receiving ventilation support.

There were 55 people in hospital in the previous reporting period, after a peak of 64 earlier in the week.

There have been 99,471 cases of COVID-19 reported in the ACT since March 12, 2020.

About 40 per cent of future COVID-19 cases in the ACT will go unconfirmed by tests for the virus, health authorities have said, before the territory embarks on the most relaxed isolation requirements since the pandemic began.

Short-term modelling on case numbers predicated stable cases over the coming weeks that were generally inline with current daily case counts, a spokesman for ACT Health said.

"ACT Health does not model the historic number of unreported cases, which international and interstate experience shows are generally mild or asymptomatic cases," the spokesman said.

"Instead, ACT Health has used modelling to predict future short-term projections of daily cases numbers, hospital and ICU admissions."

A woman in her 80s died with COVID-19 in Canberra, ACT Health said on Saturday, confirming the 50^th death of a person with COVID-19 in the ACT since the start of the pandemic.

The ACT's latest epidemiological report has revealed that most people who died with the virus in the territory had not received three vaccinations.
