The Moderna vaccine has been approved for use by Australia’s medical regulator with one million doses due in September.
Prime Minister Scott Morrison said the green light was an “important step” forward for the nation’s vaccine rollout.
“This is another important tool we have in our battle against COVID,” he told reporters from Canberra on Monday.
“We’ll have it in our hands and we will have the jabs in our arms starting next month.”
The Therapeutic Goods Administration has given provisional approval for the use of Moderna for Australians aged 18 and over.
The government says the first one million doses are expected to arrive next month, with supplies to be directed to pharmacies.
The vaccine rollout would then be bolstered by 3 million doses in each month of October, November and December.
Australia has ordered 25 million doses of the Moderna vaccine, with 15 million due to arrive from 2022.
