Both restaurants were found to have allegedly exceeded limits on how many people were allowed inside the venue at one time.

Patrols carried out by ACT Policing and Access Canberra found in one instance a restaurant had double the maximum amount of people inside.

A patrol on September 4 revealed that one restaurant had 53 diners inside at the time when the occupancy limit was 43.

The following day, another restaurant had 49 people inside when its maximum occupancy was 25.

Restaurants and other venues are limited to one person per four square metres under coronavirus rules.

In addition to the two restaurants, police have issued six coronavirus infringements, three of those to businesses while the other three were for individuals since the start of the pandemic, including 15 cautions and one arrest.

ACT police superintendent Stephen Turnbull said while the majority of businesses were compliant with the restrictions, there were some instances where the rules were flouted.

"During inspections, our primary concern is the maximum capacity limit being adhered to," Superintendent Turnbull said.

"The rules are in place for a reason and ACT Policing will continue to work with ACT Health and Access Canberra to ensure business compliance."

It comes as a new contact tracing app for Canberra businesses and patrons, Check in CBR, was launched this week.

The app will log the details of diners and visitors to Canberra locations for 28 days to assist health authorities in contact tracing should a coronavirus case be detected.

Superintendent Turnbull said there had been multiple businesses that had been inspected multiple times.

"We have generally found businesses are eager to work with us if there are any areas of concern and quickly take all the steps needed to ensure compliance with the health directions," he said.

"Businesses have their staff and patrons at front of mind because they're aware the community expects they are doing all they can for their safety."
