COVID-19 case numbers in the ACT have nearly halved in the past day, falling below 1000 for the first time in more than a week.

Thursday saw the national capital record 892 new infections, with 254 coming from PCR tests, while the remaining 648 were from rapid antigen tests.

Despite the fall in new cases, hospitalisations rose slightly with 62 patients now being treated, up from 60 the previous day.

Five are being treated in intensive care, an increase from the three recorded on Wednesday, while there are two patients on a ventilator.

It comes as ACT health authorities revealed 80 per cent of those hospitalised with COVID-19 in the Territory are unvaccinated. This contrasts with NSW where on 18 January, 33 of 36 people dying with COVID-19 had received at least two doses of vaccine.

The number of active cases in Canberra has plummeted by about one-third in the past day alone.

There are now 4,447 active cases in the ACT, down from more than 6,600 the day before.

Vaccination rates have climbed to 34.7 per cent of Canberrans over 18 having had their booster shot.

The ACT Government on Wednesday lowered the waiting time for people to receive their booster shots from four to three months since their second dose.

Almost 38 per cent of five- to 11-year-olds have received their first vaccine dose.
