The Northern Territory will keep its borders closed to all Sydneysiders for at least another four weeks, NT Chief Minister Michael Gunner has confirmed.
"There is still community transmission which means Sydney will present a threat for the foreseeable future," he said.
"For anybody who does come, they know what's waiting for them, two weeks in a supervised facility and a bill for $2500."
Other NSW locations currently on the NT's hotspot list include Port Stephens, north of Sydney, and the Eurobodalla Shire Council area on the south coast.
The entire state of Victoria was also declared a hotspot before NT opened its borders on July 17.
Mr Gunner said he expected the NT's borders with Victoria to be closed for some months to come.
"In recent weeks I think the entire nation got a reality check," he said.
"Any hopes that we'd be through the crisis in a few short months have been dashed. Right now we can't see the finish line.
"We are all in this for the long haul. Coronavirus is not going anywhere, which means our hard borders are not going anywhere."
NT recorded no new cases of the coronavirus overnight and currently has no community transmission.
