It means gatherings of up to 100 people may be allowed as early as next weekend.

The territory is due to move to stage 2.2 restrictions on June 20, which would allow more businesses to open and raise gathering limits to 50 people. But it's understood the government will jump straight to stage 3 restrictions for some elements of the territory's reopening plan.

It's unclear exactly which elements of the plan will be brought forward, but permitted gathering sizes are expected to increase.

Stage 3 of the plan would allow gatherings of up to 100 people, where social distancing can be enforced. It could allow venues which are large enough - including pubs, restaurants and cinemas - to host up to 100 people. The one-person-per-four-square-metres rule would remain in place.

Mr Barr has also pre-empted further easing of community sport restrictions.

He is due to announce the full details of the easing of restrictions on Friday afternoon, with changes to come into effect on June 20.

"I suspect a lot more of national cabinet discussions tomorrow will be on the easing of restrictions and state borders being reopened," Mr Barr said on Thursday.

"There will be an economic discussion though, and we'll have more to say about that."

It's understood the low infection rates in the ACT and NSW have given the chief health officer more confidence to approve the fast-tracking of some restrictions.

The hospitality sector is hopeful the next round of restrictions easing will allow more businesses to feasibly open. The clubs sector has been pushing for pokies to be given the green light to come back online.

Australian Hotels Association ACT president Anthony Brierley said the industry was banking on the government allowing at least 50 people per enclosed space in pubs, restaurants, cafes and bars by June 20.

"This has been their commitment and we expect the government to honour it," he said.

He wants the government to do away with the requirement for table service and the need to buy food with alcohol, saying the rules were not supported by scientific evidence.

The industry is also pushing for the halving of social distancing requirements, from one patron per four square metres to one patron per two square metres.

"TABs should be permitted to reopen, both in agencies and licensed venues," Mr Brierley said.

"Lotteries like KENO - already permitted in newsagents - should be permitted to resume in licensed premises."
