The Northern Territory has been rocked by one of the biggest earthquakes in Australia's recent history.
The magnitude-6.1 quake struck early Saturday morning about 125km west of Uluru, according to Geoscience Australia.
"Australia in recorded history hasn't had that many earthquakes of magnitude-6 and above," Geoscience Australia senior seismologist Jonathan Bathgate told AAP.
One of Australia's largest earthquakes hit in 1998 when a magnitude-6.3 earthquake struck off the WA coast.
In 1989, 13 people were killed when a 5.6 quake hit the NSW town of Newcastle.
Mr Bathgate told AAP reports of Saturday's earthquake had come in from as far away as Coober Pedy.
"It certainly is a sparsely populated area and that's probably a very lucky aspect," he said.
NT police said there has been no reports of damage or injury from the shake, SBS reports.
