Anyone seeking to enter the NT must fill in a border arrival form to declare:

You can't self-quarantine at a park or reserve.

"If you are staying in the Northern Territory, you must self-quarantine at the nearest available suitable accommodation," a NT Government spokesman said.

Accommodation options are available throughout the Territory, with a number of roadhouses and wayside inns offering rooms suitable for self-quarantine purposes.

For two full weeks, you will need to stay in accommodation with a bathroom and not leave the room.

"Accommodation providing shared bathroom facilities and/ or communal kitchens are not suitable for the purpose of self-isolating," the spokesman said

The Caravan Industry Association of Australia chief executive Stuart Lamont said caravan parks stood ready to assist with the quarantining of arrivals from Australia's international airports.

Designated facilities will be determined by the relevant state or territory government and will ordinarily be in the city of entry where the traveler has cleared immigration, but facilities in other areas may be used if required at the discretion of each government.

"We have caravan park accommodation in Perth, Adelaide, Brisbane and Melbourne which are all close by to international airports and would be ideally suited to be part of the solution around self-isolation for returning Australians from overseas announced this morning," Mr Lamont said.

"We are asking for cabin accommodation within caravan parks to be treated the same as hotels and motels with regard to workers and those required to self-isolate."

"We can be part of the solution in the government's initiative to stop the spread of COVID-19 and are frustrated that up to 38,000 cabins may sit idly empty around the country unnecessarily. We implore state governments to pick up the phone and activate our industry to support you in this time of need."
