The Northern Territory has now declared areas of Queensland, including Brisbane, coronavirus hotspots.
From today, any arrivals from Brisbane, Logan and Ipswich will be required to go into mandatory supervised quarantine for 14 days.
These areas of Queensland join Victoria, Sydney and other NSW hotspots as a risk to Territorians.
It follows the NT's first positive case for several weeks after a Darwin man tested positive for coronavirus after arriving on a flight from Melbourne yesterday.
The man is now under the care of Top End Health Service.
All close contacts to the man have now been notified and are in mandatory supervised quarantine at Howard Springs Quarantine Facility.
All 33 cases of COVID-19 in the Northern Territory are related to international or interstate travel, with no cases of community transmission.
Chief Minister Michael Gunner yesterday said while the numbers in Brisbane are still low, the Chief Health Officer has considered the data and advised that the risk of spread in these areas is unacceptably high.
"I know this may shock people. I know it will disrupt a lot of lives. And I'm sorry about that," Mr Gunner said.
"We've seen what happens when you wait too long or act too slowly with coronavirus."
