The Northern Territory has reported another 760 COVID-19 infections including more cases in remote communities under a seven-day lock-in.
In a Facebook post, Chief Minister Michael Gunner said Sunday's case numbers had also been revised up from 849 to 901 after the inclusion of more rapid antigen test results.
Of the new infections revealed on Monday, 27 were reported at Gawinwin'ku on Elcho Island which has begun a week-long lock-in to stem the spread of the virus.
The lock-in, which allows locals to move around, but not leave the island, will continue until February 6 and comes after the end of a more restrictive lockdown in the area.
Coronavirus cases in the area have now grown close to 350 since January 10 with around 300 of those considered active infections.
Masks must also be worn both indoors and outdoors, particularly where people cannot socially distance, with more masks being sent to the island to bolster supplies.
"The rules of the lock-in allow people to move around Galiwin'ku and the Elcho homelands, but people cannot leave Elcho Island to go to other parts of Arnhem Land or places like Darwin and Nhulunbuy," Secure NT said on Monday.
"This is because there is more COVID-19 and the government wants to stop it spreading to other places like Gapuwiyak and Ramingining.
"Residents of Elcho Island can return but will need to stay once they are back. Essential workers who are fully vaccinated can continue to enter and exit."
Lock-ins are also in place in other communities including Ampilatwatja, Palumpa, Milingimbi, Milikapiti, and Wessel Island including Martjanba.
Mr Gunner said 114 people were in hospital with COVID-19 across the Territory with five of those in intensive care.
The NT has about 5,550 active coronavirus infections.
