There has been another confirmed case of COVID-19 in the Territory overnight.
That brings the official coronavirus tally in the NT to six.
Again the latest case is travel-related.
Health officials said the 75-year-old man followed the recommended health protocols and there is no community spread of the virus at this time.
The man returned to Darwin from Sydney on QF840 on Friday arriving at 1pm.
The Top End Public Health Unit will be in touch with close contacts over the next 24-hours, and in line with national clinical advice other passengers on the flight should monitor their health until Friday, April 3 and arrange testing if they develop any symptoms.
The man and his partner both followed all public health protocols and went straight into isolation, and there is little risk to the NT community.
He has been admitted to Royal Darwin Hospital. All confirmed COVID-19 cases in the NT remain at Royal Darwin Hospital.
All six cases in the Territory now were overseas travellers.
