The looming deadline for certain Territory workers to get the jab in order to keep their job has also pushed people into rolling up their sleeves, according to Katherine West Health Board CEO Sinon Cooney.

"The looming deadline of needing to be vaccinated by the end of this week has changed the narrative a little bit in the bush," Mr Cooney said.

"Those who were sitting on the fence waiting for a reason or were mildly hesitant have come forward to get vaccinated.

"There's been a sharp uptick in the last couple of weeks...we expect that will improve again this week."

He said there had also been a slow but steady increase in uptake of the vaccine among the organisation's Indigenous clients too.

"Two or three weeks ago we were around 28-30 per cent first dose, now we're around 45-50 per cent first dose," Mr Cooney said.

"We'd love to be at 80 per cent, but it's just a slow burn."

Team members from the Royal Flying Doctors Service are set to spend a week in the community of Timber Creek administering vaccines.

COVID Project Officer for Wurli-Wurlinjang, which services the Katherine town and surrounds,Antony King said the lock-out has prompted a surge in people getting vaccinated and also seeking their vaccination paperwork.

In the current "lockout conditions", people must provide proof of being fully vaccinated in order to move freely in the community.

"There's certainly a lot of activity down in the vaccination centre," he said.

"A lot of people are looking for their certificate so they can move around, there's also a lot of people getting vaccinated.

"People are arming themselves with whatever they need to be able to move around."
