The Northern Territory Police Force can confirm a 79-year-old man has died at Nitmiluk National Park.

The German national was part of a tour group that was camping within the National Park.

Around 3:30pm yesterday, the JESCC received a report that the man had not returned to the camp after leaving on foot that morning.

Emergency services personnel, along with members from the NT Parks and Wildlife Department, deployed to the area and began search operations.

At 5pm, the man was found deceased on a track in the Southern Rockhole area.

A crime scene was established and at this stage the death is believed to be non-suspicious.

A report will be prepared for the Coroner.
