Under the national reopening plan, the Commonwealth automatically lifts its hotspot declaration once more than 80 per cent of a state or territory's 16-and-over population has received both doses.

The ACT ticked over that threshold on Monday, more than two months after it was officially declared a Commonwealth hotspot, and the declaration was lifted a minute before midnight.

Commonwealth support will be wound down over the coming fortnight.

Federal Emergency Management Minister Bridget McKenzie said claims for support had already been on a downward trend.

"While it's fantastic to see people in the ACT returning to work, the payment will remain available to workers who continue to be impacted by restrictions for another two weeks," she said.

Canberrans who have lost at least eight hours of work will be able to access $450 in the first week after the declaration lifted, cut to $320 in the second week.

An extra $100 available to those receiving Centrelink or the veterans support will remain for the first week, but cease for the second.
