The ACT's COVID-19 death toll remains at 78.
With a cancer clinic closed following a COVID-19 outbreak, the ACT has been warned to brace for another wave in infections.
On Tuesday, Canberra Hospital Cancer Centre clinic Paul Craft said while there was a "significant outbreak" at the clinic they have not had any new cases for four days.
"No one's got very ill from it fortunately so we haven't had to transfer patients to the COVID ward," he said.
The ward has been closed until all patients recover, meaning others in need of cancer treatment are in other parts of the hospital.
People who have had a COVID-19 booster shot are far less likely to die or be hospitalised with the Omicron variant.
An Australian-first study on the effectiveness of coronavirus vaccines has found a third COVID jab provides two thirds more protection from death or hospitalisation from Omicron.
The National Centre for Immunisation Research and Surveillance found having a booster provided 65 per cent better protection against hospitalisation and death from Omicron, compared with someone who had two doses.
People aged over 70 saw significant benefits - the study finding for every 192 people over 70 who was boosted, at least one hospitalisation or death had been prevented.
