A search is underway for a light plane with two people aboard that failed to arrive at its destination in the Northern Territory's Top End more than a day ago.
The pilot and one passenger took off in the aircraft from Gove Airport in East Arnhem about 8.30am on Saturday, NT Police say.
The plane was due to land at Katherine, 530km southwest, about two hours later but it never arrived.
Police and the Australian Maritime Safety Authority have been looking for the aircraft in remote parts of the Top End since Christmas Eve.
