The federal government on Sunday launched a new campaign promoting an expanding network of vaccination sites, targeting a "younger" age group.
Health Minister Greg Hunt said research showed a growing number of people were willing to be jabbed, as the nation looks to a 70-80 per cent fully vaccinated rate before easing lockdown and travel restrictions.
"Eighty-one per cent of people say they will be or intend to be vaccinated," Mr Hunt said.
"This campaign targets those who are still unsure to be vaccinated, as it will enable them to do things they enjoy, such as being with family, attending weddings, going to concerts and travelling."
Meanwhile, Premier Daniel Andrews announced a series of pop-up vaccination hubs will be set up across Victoria, with the first five slated for COVID-ravaged areas.
As the state reported 392 new locally acquired COVID-19 cases on Sunday, Premier Andrews said the 100 pop-up vaccination hubs will be established across 100 "priority postcodes".
"Postcodes where there are case numbers, postcodes where there are perhaps not enough people through the vaccination program," he told reporters.
"This will be done in stages. The first of those are five community-based pop-ups.
"They will be in areas that need the most. So in the outbreak areas where cases are potentially growing in Hume, Dandenong and Casey."
The first of the pop-up hubs will open within days and demand will determine how long they remain before moving on.
The initiative has been incorporated into the state government's push to get all 12-year-old and up students vaccinated by the end of the school year.
Some 70 schools will become pop-up sites, with the first eight in Dandenong, Point Cook, Werribee, Gladstone Park, Caroline Springs, Brunswick and Tarneit.
Of the new cases announced on Sunday, 255 were from the city's north and another 89 came from the western suburbs.
Another five infections were detected in regional Victoria, including one in Greater Geelong, one in Mildura, two in Gippsland and one related to V/Line.
More than 66 per cent of eligible Australians aged over 16 have received at least one COVID vaccination and 41 per cent are fully vaccinated, with some 22 million doses administered across the country.
South Australian Premier Steven Marshall told the program his state is on board with the national plan and expects state lockdowns and lockouts will be a thing of the past before Christmas when the 80 per cent vaccination rate is met.
"There is a lot of time to go until we get to that position, but we do know that as we increase our vaccination rate we reduce that transmission rate, we reduce hospitalisation," he said.
NSW is already planning for its domestic reopening at a 70 per cent vaccination rate, even though its daily infection rates remain stubbornly high at above 1000 and the death toll continues to steadily climb.
Federal Labor frontbencher and NSW MP Tanya Plibersek is looking forward to reopening, but has some concerns.
"I would be much more confident about the 70 per cent target if it was clear the premier was getting health advice that backed it," she told ABC's Insiders program.
Queensland authorities are breathing a sigh of relief after recording no new COVID-19 cases on Sunday, having warned that it might have to take swift action after detecting five cases the day before.
