There is intense pressure on the NT Government to place a ban from July 17 on all Victorians.

The government yesterday decided to abandon its ban on Melbourne's suburban hot spots and make all of Melbourne a hot spot.

The "hard border" closure to Melbourne will extend beyond July 17.

"I will stop travel from hot spots wherever they are, whenever they appear. And today I have made the decision that all of Melbourne is a hot spot," Chief Minister Michael Gunner said.

"We had already declared six areas in Melbourne as COVID-19 hot spots. Following today's new cases in Melbourne, I asked the Chief Health Officer to review the situation to determine if additional locations needed to be considered as hot spot areas.

"The Chief Health Officer's advice is that there are outbreaks in Melbourne suburbs that have not yet been identified as hot spots.

"He also advised me that while these outbreaks are confined to the Melbourne metropolitan area, they extend across Melbourne, making them more difficult to contain to specific suburbs.

"As a result of this advice, I have directed him to designate every local government area in Greater Melbourne as a COVID-19 hot spot, for the purposes of travel to the Northern Territory," Mr Gunner said.

NSW is closing the borders to travelers from Victoria from tomorrow.

Other states like Tasmania and South Australia are reviewing their border arrangements.

"This means that from July 17, anyone who lives in or has visited the greater Melbourne metropolitan area will still not be permitted free access to the Territory," Mr Gunner said.

"Our borders will stay closed to Melbourne until further notice.

"Any arrivals will be required to undertake 14 days of mandatory supervised quarantine, most likely at the Howard Springs facility, at their own cost.

"These rules applies to everyone, not just Victorians. That includes Territorians. Territorians should reconsider any planned travel to any location in Melbourne in the near future.

"Right now, the problem is confined to Melbourne, but we will keep a watching brief on the rest of Victoria.

"Hot spot areas may be added prior to 17 July, depending on the health advice. However, I want to make clear that no area in the greater Melbourne region will be removed from the list prior to 17 July. They will stay shut off from the Territory until further notice.

"This gives interstate travelers certainty about our rules.

"Most importantly, it gives Territorians confidence that our hard borders will stay in place for any area, in any part of Australia, which poses an unacceptable risk to the Territory."
