The ACT has reported 1078 new cases of COVID-19 in the 24 hours to 8pm Tuesday.
The new cases bring the active total to 5601.
There are 23 people in hospital because of COVID, three of them are in intensive care, and two are being ventilated.
This comes as NSW and Victoria record a combined death toll of 42, a grim milestone for both states.
In December, ACT Health Minister Rachel Stephen-Smith said health authorities had expected before Christmas the hospitalisation rate to be higher by the new year, and projections always took into account the potential impact of COVID-19 cases in the surrounding NSW region.
There were 3586 negative tests received in the 24 hours to 9am Wednesday.
Meantime, the percentage of the eligible population who have received booster shots has reached 25.6 per cent.
