More disadvantaged parts of Australia, including COVID-hit southwest Sydney, have some of the country's lowest vaccination rates.
Just 14.6 per cent of people aged 15 and older in southwest Sydney have received both vaccine doses as the city's coronavirus outbreak worsens.
The federal government has released data detailing vaccination rates across Australia from the start of the rollout up until Sunday.
The Grafton region in NSW has a similar jab rate to southwest Sydney.
Just 14.1 per cent of people in the NSW Hunter Valley region, excluding Newcastle, have received both doses.
The rate falls to 13.6 per cent in the state's far west.
Meanwhile, Victoria's lowest double dose rate is in Melbourne's northwest.
It climbs to 16 per cent and 16.5 per cent in the city's southeast and west, respectively.
People in Queensland's Mackay, Isaac and Whitsunday regions are that state's lowest vaccinated, sitting at 10.2 per cent.
Just 13.2 per cent of people are fully immunised in Logan and Beaudesert
Across central Queensland, the rate rises to 14.7 per cent of people.
In the Darling Downs, Maranoa and Ipswich regions, 15.3 per cent and 15.7 per cent of the population, respectively, are jabbed up.
Australia's lowest vaccination rate is in the northern part of outback Australia, where 8.6 per cent of people are double dosed.
The rate for Perth's southeast and WA's Wheatbelt region is sitting at 15.1 per cent. It falls to 14 per cent for northwest Perth.
In Adelaide's north and South Australia's Mid North, 15.4 per cent of people have received two doses.
Australia-wide, just under 20 per cent of people aged 16 and older are fully immunised.
Prime Minister Scott Morrison on Tuesday told reporters there was strong demand for the vaccine.
The head of the country's vaccine task force, Lieutenant General John Frewen, said they were trying to ensure more uniform rates across states and territories.
