The ACT has reported 23 coronavirus cases following the extension of Canberra’s lockdown for another fortnight.

Concerns about continued unlinked infections and people unknowingly out and about with the virus, means lockdown will run until at least September 17.

Chief Minister Andrew Barr said 14 of Wednesday’s cases were linked and 11 had been in quarantine throughout their infectious period.

He earlier warned restrictions could not ease significantly until at least 80 per cent of the eligible population had been vaccinated.

The outbreak in NSW, which has recorded its fifth straight day of 1000-plus new local cases, means Canberra remains vulnerable.

To soften the blow of another two weeks of lockdown, the ACT is relaxing some restrictions, including allowing small weddings, funerals and outdoor gatherings.
