COVID cases in the ACT are edging towards four digits with 926 new cases reported in the 24 hours to 8pm Monday.
Cases are up by 412 from 514 reported on Monday.
The new COVID-19 cases bring the active total to 2789.
Meanwhile, the testing clinic at Holt has closed for Tuesday due to a blackout.
There are 13 people in hospital because of COVID, with one in intensive care, and one on ventilation.
On Monday, Health Minister Rachel Stephen-Smith said the hospitals were preparing for the worst-case scenario, but so far the worst predictions had not eventuated.
"The team is working on the basis of a worst-case scenario of seeing a few dozen people potentially in hospital by late this week, early next week. So they're doing the planning around what that might look like," Ms Stephen-Smith said.
"We know that's not entirely unrealistic, but we're also hoping our very high vaccination rates here in the ACT will keep those numbers of people needing to be hospitalised - and particularly that number of people needing intensive care - as low as possible."
There were 3485 negative tests received in the 24 hours to 9am Tuesday.
Meantime, the percentage of the eligible population who are now fully vaccinated remains at 98.5 per cent.
