The company is also considering using Australia as a trial country for children as young as six months if the medicines regulator grants approval.
Finance Minister Simon Birmingham said the government ultimately wanted people of all ages included in the rollout.
“Moderna’s looking at a global trial, Australia may be part of that, but that will be subject to all of the technical and scientific advice that needs to be provided,” he told Sky News on Monday.
The Therapeutic Goods Administration is expected to approve Moderna for over-16s in coming weeks with around one million doses slated to arrive next month.
That will ramp up to three million in October, while bigger Pfizer shipments are also on the way with two million doses a week set to land from September.
While the rollout is considered one of the slowest in the developed world, Senator Birmingham said Australia was slightly above the global average.
“There will be a very strong supply coming to build on what is already a record rate of vaccination happening now,” he said.
Australia has fully vaccinated 22 per cent of people aged 16 and over.
Birmingham is confident the nation can achieve high enough vaccination coverage to ease interstate travel restrictions and reunite families at Christmas.
