The ACT's coronavirus restrictions are easing further, with Canberra's pubs and bars to be able to accommodate more patrons indoors.
The changes, announced last week, take effect on Wednesday.
Businesses that have registered with the Check In CBR contact tracing app will be allowed to have one person per two square metres in their venues.
More than 2700 businesses across the ACT have signed up to the Check In CBR app, which has been downloaded more than 80,000 times since it was launched. Venues will have until December 16 to start using the application.
The cap on crowd numbers at Manuka Oval and Canberra Stadium will be lifted to 65 per cent of the venues' capacity.
Cinemas and theatres will also be able to sell 65 per cent of their seats, up to a maximum of 500, provided the venues are using the government's contact tracing app to collect patron details.
But the easing of restrictions comes with a warning from ACT health authorities.
More people gathering outside due to warmer weather along with end-of-year celebrations could increase the risk of COVID in the ACT in coming months.
Marking the beginning of summer on Tuesday, acting ACT chief health officer Vanessa Johnston urged Canberrans to be more alert during the warmer months with more large gatherings and festivities taking place.
"If a case was to occur there's a much greater risk of transmission into the wider community and people need to stay vigilant," Dr Johnston said.
"When things start to open up, like gathering restrictions being relaxed, then people can become complacent.
"What I'm asking people is to celebrate, it's been a hard year, but stay COVID-safe."
Canberrans have been also urged to avoid large crowds where social distancing is difficult to be carried out, such as busy times at shopping centres during the Christmas rush.
Dr Johnston said COVID considerations should also be made when hosting events during the summer period.
"When the weather permits, host celebrations outdoors or if you hold an event inside, increase the ventilation inside.
"When Canberrans are out and about ... take extra care with people particularly with others you don't know and if an area is too crowded, stay away and go back another time."
Despite the larger gatherings being held across the city and bars, pubs and restaurants allowed to have more patrons, ACT police have said compliance patrols won't be ramped up during summer.
Chief police officer Neil Gaughan said regular patrols were already carried out would continue at pre-existing levels.
"Compliance checks are the same as they have been," he said.
"We'll be patrolling precincts and making sure that people do the right thing and comply with the restrictions so Canberrans can enjoy their summer as much as possible."
Deputy commissioner Gaughan said while the issue had gone away since the earlier days of the pandemic, some Canberrans were still leaving fake names on contact tracing forms at venues across the city.
"I think people are well educated at what the restrictions are, and we have focused our entire police arrangement around coronavirus that we've been maintaining an education process," he said.
"We'll be flexible where we nee to be, but if people are blatantly going outside the rules, we'll issue infringements."
Health Minister Rachel Stephen-Smith said the changes struck a balance between moving forward and protecting the community from COVID-19.
Restrictions will next be considered in February.
"This will give the chief health officer enough time to review these changes and make deciosisn based on the current health advice ... post the busy summer holiday period," she said.
Ms Stephen-Smith said widespread us of the Check-In CBR app would give the government confidence it could respond to an outbreak quickly and effectively.
The check-in details go directly to ACT Health and are only accessed in the event of a COVID case at a location a user has visited.
