The pandemic death toll remains at 31.

The new cases were diagnosed from 303 PCR tests and 186 rapid tests.

The number of ACT residents aged 12 and over who are fully vaccinated remains at 98.6 per cent.

A total of 58.9 per cent of people have received their booster, and 75.1 per cent of children aged 5-11 are vaccinated with a single dose.

Walk-in vaccinations will be available for five to 11 year olds from 9am to 5pm on Saturday at the AIS Arena, as the mass vaccination clinic is transformed into a superhero centre.

Nurses and support staff will be in superhero costumes, and little ones (and their carers) have been encouraged to dress up as their favourite superheroes, too.

Local superheroes and favourite characters will drop in throughout the day to make children feel welcome. Depending when families visit, they might run into characters from Paw Patrol, Princess Belle from Beauty and the Beast, Canberra Capitals Cappie, Captain Starlight from the Starlight Children's Foundation or Canberra Hospital Foundation mascot Hearty.

Real life heroes from the Emergency Services Agency are joining in the fun, bringing fire safety mascot Sparky and SES mascot Paddy, plus service vehicles and fire trucks.

Superhero-level extra security and work, health and safety measures are in place to keep everyone in and around the AIS Arena clinic tomorrow safe and happy throughout the event.

Despite a video that surfaced on social media on Thursday night targeting the campaign, Chief Minister Andrew Barr said the AIS will remain a "safe place for vaccinations to take place".

The Chief Minister said authorities were aware of the threat, and access points into the vaccination hub would be "well protected".

"Parents should feel confident that they're coming to superhero Saturday with their kids to get vaccinated and that will be managed safely," he said.

"Certainly people are not going to be standing over you whilst you're waiting in line. So I think it will be a safe place for vaccinations to take place".

Meanwhile, mandatory mask wearing indoors could continue throughout winter for the ACT.

This comes after the Health Minister indicated on Thursday that some public health restrictions could be relaxed in a fortnight if the COVID situation in the territory improves.

A range of public health measures could be removed by the end of the month bringing dancing back to the capital and scrapping density limits.

However, mask wearing is not expected to end anytime soon.

"Indoor mask wearing is not a big imposition on people, it's something that's very simple for all of us to do to just reduce the risk of transmission," the minister told ABC Canberra on Friday.
