THE CITY'S Pfizer surge was no "one day avalanche", Bendigo Health chair Bob Cameron says as bookings continue to flood in.
Another 4000 people have booked in for their first Pfizer jab since 9am on Wednesday when the first 17-year-old was vaccinated at the Mollison Street centre under eased age restrictions.
It means 9000 people have now booked in since Tuesday's announcement that Pfizer vaccines would be open to people aged 16 to 39, Mr Cameron said.
"Young people might be frustrated about the slow rollout of the vaccine rollout but, to their credit, they are rolling up their sleeves and doing something about it," he said.
Bendigo Health warned on Tuesday that anyone wanting to get their first Pfizer jab by the end of September would need to act fast given the high demand, which has helped crash booking websites and triggered long delays on phones for many people around town.
The health service currently expects to run out of available September slots some time in the next few days and is now offering times up until 10 October.
The hub is understood to be vaccinating about 900 people a day, this week hitting a record 933.
Numbers are capped to help manage the supply of vaccine so it is unlikely Bendigo Health will knock its record out of the park any time soon, Mr Cameron said.
That could change rapidly though depending on when more vaccine arrived, he noted.
Meanwhile, the federal government expects to announce plans to vaccinate children as young as 12 within days.
Prime minister Scott Morrison expects to reveal the guidelines for those aged 12 to 15 years old on Friday.
"As the vaccine supply continues to increase week by week ... we will be able to vaccinate those aged between 12 and 15, alongside the rest of the population in weeks and months," he told parliament during Question Time.
NAB chief executive Ross McEwan also weighed in to the vaccine debate at an Australian British Chamber of Commerce event, claiming "Freedom Day" should be pencilled in for Melbourne Cup day.
The date is roughly around when immunisation rates should exceed the 70 per cent threshold.
Mr McEwan said states and territories need to stick to the plan for the benefit of the economy and for Australia to begin living with the virus.
"We've got a national plan, let's stick with it and then this economy will open up and it will grow," he said.
