Almost three-quarters of Australians aged 16 and above have received their first coronavirus vaccine dose seven months into the rollout.
More than 10 million people are fully vaccinated, with 48.5 per cent of the over-16 population having received both jabs, while 73.4 per cent have had a single shot.
A national reopening agreement has set 70 and 80 per cent double-dose coverage as crucial milestones to easing restrictions.
Prime Minister Scott Morrison, who is meeting with world leaders in the United States, continues to entice people to be vaccinated with the prospect of borders opening.
“We keep that up, people will be able to travel again. Particularly in those states that are achieving those marks,” he told reporters in Washington DC.
“I want to encourage everyone across Australia to go and get that jab.”
Almost one in five per cent of children aged five to 11 have received a jab in the eight days since they were included in the rollout.
Tourism and Trade Minister Dan Tehan said the nation was on track to lift travel restrictions this year.
“I do empathise with the Australians who have been denied the opportunity to travel overseas this year. It's another reason why everyone should get vaccinated,” he told the National Press Club.
“We have to stick to the national plan that will see our international border open up – at this rate by Christmas at the latest.”
More than 45,000 Australians are stranded overseas with the figure rising in recent months due to reduced passenger arrival caps.
About 4700 are considered vulnerable.
Mr Tehan confirmed travel bubbles were under negotiation with other countries, mirroring the New Zealand arrangement.
“That will mean there will not be the restrictions on 14-day quarantine that otherwise would be the case for people returning to Australia,” he said.
Labor leader Anthony Albanese said the federal government leaving arrival caps to states and territories was absurd given it was responsible for customs, immigration and borders
“It is terrible that people are stranded. We need to fix it,” he told ABC radio.
“This is a tragedy for people who are stranded overseas. It's also a tragedy for people here who want to see their loved ones.”
