Canberra will receive 86,797 Pfizer doses from the federal government, as part of the 4 million additional doses it secured in a swap deal with the UK.
"This is above our population share, the reason for this is that there is rebalancing under way across Australia," Chief Minister Andrew Barr said.
"To see the the jurisdictions that didn't receive their per capita share of the Poland 1 million doses, or the Singapore 500,000 doses are seeing that now made up in this 4 million swap from the United Kingdom."
Mr Barr announced the distribution on the same day the ACT recorded 32 new COVID-19 cases, the highest it has recorded in any 24-hour period.
"We've seen through the pandemic that daily numbers can be volatile. These headline numbers are not what we wanted today," Mr Barr said.
"Our contact tracers are now going to have a very busy weekend."
The newly allocated Pfizer doses will largely go to Canberra's GPs and pharmacists and will arrive on a week-by-week basis, Mr Barr said.
The first shipment is due to leave the UK this weekend. Mr Barr anticipated that once it had landed in Australia and undergone batch testing by the Therapeutic Goods Administration (TGA), Canberra would receive the first allotment at the end of next week.
Mr Barr said a decision on moving second doses of the AstraZeneca vaccine forward "is one that is under consideration".
In government clinics second doses are administered 12 weeks after the first dose, though it is possible to book a second dose earlier at pharmacists and GPs.
"It's obviously an issue that requires firm medical advice coming out of ATAGI," Mr Barr said.
Seventy per cent of the ACT population aged 16 and over will have received at least their first dose of a COVID-19 vaccine this weekend.
On Saturday, 69.5 per cent of the population aged over 16 had received their first dose; 46 per cent were fully vaccinated.
The AIS mass vaccination hub administered 1451 doses on its opening day on Friday. This will increase significantly as more Pfizer doses become available, Mr Barr said.
The hub has a daily capacity of 24,000 doses per day.
The TGA has also given provisional approval of the Moderna COVID-19 vaccine for children aged between 12 and 17.
"We're also expecting pharmacies to start administering the TGA-approved Moderna vaccine," Mr Barr said.
"With the announcement this morning that that will be available for people 12 years and older by the end of this month, there's going to be many more options available for people to get vaccinated sooner."
