A US marine has tested positive to coronavirus in Darwin.

Health Minister Natasha Fyles said the 21-year-old Marine arrived in the city a few days ago on a charter flight.

She said the Marine had very minimal contact with any residents after he travelled through the military side of Darwin airports to the Robinson barracks.

“The man has been in quarantine since his arrival in Darwin on 8 July,” NT chief minister, Michael Gunner told reporters.

All 32 cases of COVID-19 in the NT are related to international or interstate travel, with no cases of community transmission.
