The US and Canada are already vaccinating children as young as 12.
Moderna says its COVID-19 vaccine strongly protects children as young as 12, a step that could put the shot on track to become the second option for countries already vaccinating teenagers.
The Australian government has signed a deal for 25 million doses from the Massachusetts-based company but the Therapeutic Goods Administration is yet to approve it.
Currently, the youngest Australians approved to be vaccinated are 16, with jabs rolling out to some South Australian teens.

With global vaccine supplies still tight, much of the world is struggling to vaccinate adults in the quest to end the pandemic.
But earlier this month, the US and Canada authorised another vaccine — the shot made by Pfizer and BioNTech — to be used starting at age 12.
Moderna aims to be next in line, saying it will submit its teen data to the US Food and Drug Administration and other global regulators early next month.
The company studied more than 3700 12- to 17-year-olds. Preliminary findings released on Tuesday showed the vaccine triggered the same signs of immune protection in children as it did in adults, along with the same kind of temporary side effects such as sore arms, headaches and fatigue.
There were no COVID-19 diagnoses in those given two doses of the Moderna vaccine compared with four cases among children given dummy shots.
In a press release, the company said the vaccine appeared 93 per cent effective two weeks after the first dose.
While children are far less likely than adults to get seriously ill from COVID-19, they represent about 14 per cent of the US's coronavirus cases.
At least 316 have died in the country alone, according to a tally by the American Academy of Pediatrics.
With plenty of vaccine supply in the US, younger teens flocked to get Pfizer's shot in the days after FDA opened it to them, part of a push to get as many children vaccinated as possible before the next school year.
Both Pfizer and Moderna have begun testing in even younger children, from age 11 down to 6-month-old babies. This testing is more complex: teens receive the same dose as adults but researchers are testing smaller doses in younger children. Experts hope to see some results in the Australian Spring.
