Children as young as 12 will soon be offered the Pfizer coronavirus vaccine after the jab was approved for use in kids.
Before today only those aged 16 or over were recommended to get the jab.
The Therapeutic Goods Administration, which oversees Australia's medicines and vaccinations, has approved the vaccine for over 12s.
The Australian Technical Advisory Group on Immunisation must now give its approval before it can be rollout out to teenagers.
For children with under-lying health conditions which can make coronavirus more serious, approval to get the vaccine is set to be fast-tracked.
Health Minister Greg Hunt said the the new vaccination program would aim to 'protect children' and was an 'important and welcome additional step'.

The official approval through the ATAGI should take around four weeks, amid a spate of outbreaks within schools in Victoria.
Several New South Wales schools have also been affected during Sydney's recent outbreak, including South Coogee Public School in the city's east where at least four children tested positive.
The outbreak forced 555 primary school students into two weeks of isolation after they were deemed close contacts.
Children as young as 12 have already been receiving vaccines in America for several months.

In the UK, Pfizer has not yet been approved for anyone under the age of 16.
However those most at risk as young as 12, including children with severe disabilities, immunosuppression disorders and Down's syndrome can get the jab.
The huge change to Australia's vaccine rollout comes after Scott Morrison apologised for the program not meeting its targets but insists some of the issues were out of his control.
The prime minister had repeatedly refused to say sorry for the bungled immunisation program, which is lagging behind most of the developed world.
'I'm sorry that we haven't been able to achieve the marks that we had hoped for at the beginning of this year - of course I am,' he told reporters in Canberra on Thursday.
