Australians are expected to receive the Pfizer-BioNTech coronavirus vaccine from mid to late February, Prime Minister Scott Morrison said.
Mr Morrison said high-priority groups, including healthcare and quarantine workers among others, would receive the treatment first.
He hoped the initial phase would start with about 80,000 inoculations a week.
However, Mr Morrison said this timeline with depend on a number of factors including final approval from the Therapeutic Good Administation, and delivery of the vaccine from the supplier.
He said the Pfizer vaccine would only be delivered and released once TGA approval was given, which he anticipated would occur by the end of January.
