Remote communities in the Northern Territory's Top End have been closed to all non-essential travel in response to concerns about the spread of COVID-19.

The Northern Land Council (NLC) says all existing permits to Top End Aboriginal communities for non-essential travel will be suspended and no new permits will be granted until further notice.

The council said people who provide essential services to the community including doctors, nurses, teachers, police officers and council workers will not be affected by the ban.

Chief executive officer Marion Scrymgour said the move was to protect Aboriginal people in the communities who already faced issues like chronic health conditions, lack of resources and overcrowded housing.

"The NLC has received many calls from community members asking that we do all we can to ensure the safety and protection of Aboriginal people in their communities who are very concerned about the spread of COVID-19," Ms Scrymgour said.

"Should this virus break out in our communities, we don't have the manpower to deal with this."

She said the NLC will be launching an information campaign in Indigenous languages to inform people about hygiene, testing for coronavirus and for them to avoid travel outside communities.

NLC staff have also cancelled their non-essential travel to communities including its regional council meetings.

"Somebody could come out and they could get infected and then go back into the community," Ms Scrymgour said.

"The position we're taking is if we can push back that virus taking hold in our communities, that's a good thing. It means we can work at getting better prepared."

The decision comes after the Northern Territory Government decided it will stop its employees from making non-essential travel to remote communities.

A similar decision has also been made in the APY lands in South Australia, where visitors have been asked to sign statutory declarations about their potential exposure to the virus before being granted access to the region.

The NLC's decision will mean tourist activities like cultural tours will also be cancelled in the Top End region.

Ms Scrymgour said she will seek advice from the Federal Government and NT Government about whether tourism employees can access some support while the restrictions were in place.

She said she would also raise the concerns of Kakadu National Park Traditional Owners to the Commonwealth to decide whether park access and permits should continue.

"We've had a huge concern from Aboriginal people in the Kakadu lands, traditional owners, who are saying there's been no consultation with us about having people come in and visit when we are at risk as well," she said.

The Central Land Council said it will consider whether travel restrictions like those taken by the NLC are necessary for Central Australian Aboriginal communities next week.

It's already advised on its website, "non-resident travel to remote communities in Central Australia should be reconsidered other than required travel for health, supply and essential services personnel."

It said permits issued in the last 14 days to people who have travelled to any of the countries listed in the Australian Government travel advisories will become invalid.
