Australia has reached a significant benchmark in its vaccine rollout with the number of people aged 16 and over who have received two doses passing 80 per cent.
But in some states, immunisation rates remain worryingly low, particularly among the young, raising more concerns about Western Australia's plan to keep its border closed until it reaches 90 per cent coverage.
It's a rollout that's had its fair share of hiccups and critics, with hundreds rallying through the streets of Melbourne in protest at mandatory vaccination, chanting slogans including "No vaccine passports! No more mandates!"
But the country's COVID-19 vaccine program has finally reached a crucial milestone.
Prime Minister Scott Morrison announced the news on Saturday morning, calling it "another magnificent milestone" and a "massive national effort".
Mr Morrison praised older Australians for leading the way.
"Eighty per cent of Australians aged over 16 have now been fully vaccinated that four out of every five. How good is that? It's been a true, Australian national effort," he said.
"Ninety-nine per cent of Australians aged over 70 have had a first jab and over 90 per cent have had a second. That's just extraordinary."

While states like Victoria and New South Wales are continuing to record strong vaccination rates among the young, in Queensland less than 50 per cent of 16 to 29 year-olds are double dosed.
"The key issue here is if Queenslanders want us to open up quicker both domestically and internationally, it's in their hands," Queensland's Health Minister Yvette D'Arth said.
"Go out and get vaccinated now and we can open up sooner."

There are similarly low vaccine figures among the young in Western Australia.
And as the state announces it wants to achieve 90 per cent full vaccination before re-opening borders, it's prompted a call to arms from industry groups in the state to those delaying getting their COVID-19 shots.
Chris Rodwell is chief executive officer with the Chamber of Commerce and Industry Western Australia.
"If they are not getting that dose then they are putting WA businesses at a disadvantage. While the east coast and other states open up, WA businesses will find it harder harder to to business than their counterparts in other states. They're already facing really significant skill shortages, difficult supply chain impacts, other price impacts," he said.
With the state not expected to hit that 90 per cent mark until February, travel industry figures, like Flight Centre chief executive Graham Turner, are considering legal action.
"If you look at Queensland and WA, reaching 90 per cent particularly of over 12s is not a given. There's a fair reluctance in some areas to be vaccinated ... so it may never get there to over 90 per cent," he said.
"But if there is a definite date [given by the premier for reopening WA’s borders], that's fine."
Mr Turner described the WA government's approach as "very conservative", and called for the science behind it to be made clear.
"We would ask why is it okay for 80 per cent in New South Wales and Victoria, and Queensland, for that matter. But WA somehow wants 90 per cent?," he said.
"So let's see what is the science behind that, there must be some reason why they’re having this very conservative measurement."
