The first case of the Omicron variant of COVID-19 has been recorded in the Northern Territory.
Health Minister Natasha Fyles announced on Monday morning that a man who arrived in the NT on a repatriation flight from South Africa on November 25 has contracted the new variant.
Ms Fyles reassured Territorians that the man went straight to the Howard Springs quarantine facility and was not a threat to the broader community.
Acting Chief Health Officer Dr Charles Pain said he was not "overly concerned" about the case.
"We've dealt with variants the whole way through this... it's business as usual."
Meanwhile, a 19-year-old woman has tested positive to COVID-19 in the Binjari community in the last 24 hours, and a 17-year-old girl from Binjari has tested positive for the virus in Howard Springs.
The 19-year-old tested positive during a third round of testing in Binjari conducted over the weekend.
She and her household contacts will be taken to Howard Springs to quarantine.
"Because Binjari is still under the hard lockdown conditions we are confident that case is not a threat to the NT community."
No new cases have been recorded in the remote community of Lajamanu after 147 tests were conducted over the weekend.
The community went into lockdown on Saturday after COVID-19 was detected in wastewater in the region.
In Katherine, the Bicentennial Road wastewater catchment has returned a "presumptive positive" result as well as the Chamber Crescent catchment.
Ms Fyles said the signal was weakening but urged people in Katherine to get tested if they have any symptoms.
More to come.
