A Queensland-made coronavirus vaccine could be available to the public in the third quarter of 2021.
CSL and University of Queensland revealed on Friday enough vaccine had already been made for phase three trials, for which the manufacturer is seeking regulatory approval before the end of this year.
Early data from phase one clinical trials shows the CSL-UQ vaccine is safe, well tolerated and induces a strong immune response, UQ's Professor Paul Young said.
It has also been shown lower doses are just as effective, so the amount of vaccine being made will stretch further.
Health Minister Greg Hunt said that while the CSL-UQ version of the vaccine would not be available until late 2021, there would be other forms available by March to start vaccinating frontline health workers and others on the priority list.
Pfizer reported its candidate vaccine had a 90 per cent effectiveness rate in late-stage clinical trials.
Mr Hunt said the national goal was for all Australians who want to be vaccinated to have the shots by the end of next year.
Prime Minister Scott Morrison is meeting with state and territory leaders on Friday to discuss how to rollout the vaccines.
Mr Hunt said the strategy would involve making the vaccine available through hospitals, respiratory clinics, GPs and possibly special vaccine centres if the states agreed.
National cabinet is also considering the framework to reopen Australia by Christmas as infection rates plummet across the country.
The blueprint received in-principle support from premiers and chief ministers at the last meeting but has been criticised by doctors who warn it moves too fast.
Australian Medical Association president Dr Omar Khorshid said allowing large gatherings, more people indoors, returns to workplaces and public transport could deliver the wrong message.
"It represents a significant change in direction, sending a message to the community that will drive complacency," Dr Khorshid said.
"Living with the threat of COVID-19 means that sensible restrictions must remain part of our lives for the foreseeable future."
The Australian Industry Group, which represents some of the country's biggest employers, says committing to reopening domestic borders is a crucial step toward the eventual easing of international travel restrictions.
Deputy Opposition Leader Richard Marles urged the prime minister to show leadership.
"He needs to bring people along on a process which sees our borders open up before the end of the year," Mr Marles told the Nine Network.
The leaders will receive Chief Scientist Alan Finkel's review of contact tracing systems around the country.
Australia continues to post tiny numbers of new coronavirus cases, with no community transmission on four of the past five days.
Victoria has marked a 14-day streak without new infections while NSW has gone six days straight without a locally acquired case.
International arrival caps will be also discussed at national cabinet, with 35,000 Australians who want to return home still stranded overseas.
Special repatriation flights from New Delhi and London arrived in Darwin this week bringing home a combined 319 people.
There have been four flights into the Northern Territory capital since a deal was struck to use a mining hub outside of Darwin for two-week quarantine periods.
