One in four eligible people in the Northern Territory are now fully vaccinated against COVID-19, with data from health authorities showing the jurisdiction's immunisation rate is racing ahead of the national average.
More than 47,000 people in the NT have now received both vaccine doses.
That equates to a vaccination rate of 25 per cent, 10 per cent higher than the national average.
It follows the expansion of the NT's rollout to anyone aged 16 and over last month.
Meanwhile, Western Australia is trailing the rest of the nation, with just 12 per cent of the state's population, or 260,000 people, fully vaccinated.
Almost 45 per cent of the NT's eligible population has had at least one dose, with Tasmania and the Australian Capital Territory close behind on 44.5 and 44.3 per cent respectively.
These figures differ slightly from the federal government's vaccine count, which says the ACT has the highest first-dose vaccination rate, but does not account for a significant number of NSW residents crossing the border to get the jab.
NT Health Minister Natasha Fyles said she expected the strong vaccination rate to continue because of high demand for more appointments.
"We're working closely with the Commonwealth around supply and we've been quite public that there will be an uptick in supply of the Pfizer vaccine in September and into the end of the year," she said.
"We're working across the community to make people understand that the vaccine is safe, it's effective, it's been rigorously tested and it is their best tool in fighting the coronavirus pandemic."
In May, figures showed the NT had the nation's lowest utilisation rate for the vaccines it had been supplied, but Chief Minister Michael Gunner said that was because it needed to reserve some supplies for second doses.
