Ormiston Gorge, 130 kilometres west of Alice Springs in the West MacDonnell National Park, became a natural amphitheatre for the concert.
It was one of the final events for the 10-day Desert Song Festival, and director Morris Stuart said it was a big turnout.
"The crowd is up and happy and positive, so it's a wonderful way to round off the 2017 Desert Song Festival," he said.
"I think we had well over 1,000 people here today which put a bit of pressure on us, but logistics apart, beautiful afternoon, wonderful contribution from singers and from musicians as well.
