The Northern Territory will continue with plans to open its borders from July 17.
But the Victorian coronavirus "hotspots" will be excluded from those plans.
You will still need to complete a border arrival form and declare if you have travelled to or through a coronavirus hotspot in the last 28 days.
Anyone arriving in the Territory who has been in a hotspot will be required to self-quarantine for 14 days in a regional centre at your own expense.
The Victorian government had identified six local government areas within their state as COVID-19 hotspots, all of them Melbourne suburbs.
A hotspot is defined as more than 5 non-overseas acquired cases since June 1.
Chief Minister Michael Gunner said the NT's "hard" borders will stay in place for hotspot areas indefinitely.
"Hard borders will stay in place for all arrivals until July 17," Mr Gunner said.
"If you are in a hotspot, you should be in lockdown.
"If you try to come here, we will lock you down.
"And if you break our rules, we can lock you up."
From Friday, Queensland will move into some aspects of Stage 3 including opening the borders a week later but entry from Victoria will not be permitted.
"The border with Victoria will remain closed and will be strengthened," Premier Annastacia Palaszczuk said.
"Anyone who has travelled from Victoria including Queenslanders will be prevented from entering or will have to quarantine at their own expense for two weeks."
