The Northern Territory has recorded four new COVID-19 cases after four returned overseas travellers tested positive while quarantining near Darwin.
The 31-year-old man, 82-year-old woman and two children, both aged three, were passengers on a Commonwealth repatriation flight that arrived from India on Tuesday.
All four are in isolation at the Howard Springs camp under the care of medical staff and remain well, NT Health said on Thursday.
The total number of active cases in the NT is now five.
It follows the diagnosis of a 31-year-old woman on Wednesday, who was on the same flight from Delhi.
She tested negative for the virus before travelling, but positive at the re-purposed mining camp on Darwin's outskirts.
NT Health says returned overseas travellers are a high-risk group and five to 10 per cent could test positive for the virus.
This brings the total number of cases diagnosed in the NT to 39.
All the COVID-19 infections have been related to international or interstate travel and there have been no cases of community transmission.
