The Australian Capital Territory has recorded 22 new local coronavirus cases overnight amid concern more schools are linked to transmissions.
Chief Minister Andrew Barr said the ACT cluster had grown to 67, with 63 of those all linked to a known cluster.
"Fortunately all 22 of the new cases can be linked to existing cases and due to the excellent work of our contact-tracers," Mr Barr said.
"Now is not the time to be easing restrictions," he warned.

There are 12,500 people in quarantine in the ACT.
Mr Barr said 57 per cent of people in the ACT have had a first dose of the vaccine, and one third are fully vaccinated.
This is above the national average.
ACT Chief Health Officer Dr Kerryn Coleman said all of today's cases are linked, "which is fabulous news".
"Only four of the 67 cases are still under investigation," she added.
There are also more than 190 exposures sites across the ACT, and Dr Coleman asked people to continue to check the list on the government website.
Three more schools have been linked to COVID-19 cases in the ACT.
"We are actually now seeing more young people in our cases," Dr Coleman said.
The new schools are Harrison School Public School, University of Canberra Senior Secondary College Lake Ginninderra and St Thomas Aquinas Primary School.
There are now 15 cases linked to Lyneham High School.
An emotional Mr Barr said he acknowledged how tough lockdown was on residents.
"It's been a really tough winter across Australia and particularly in Canberra," Mr Barr said.
"I want to hold out hope for people that we will get through this, but we need to look after each other.
"Please stay at home, but do keep in touch with family and friends online and through the telephone."
