Australian man Jon-Paul Kennedy was sleeping next to his terminally-ill mother in an Indonesian hospital when a "terrifying" earthquake rocked the building.
At least 10 people died when the magnitude 6.4 magnitude quake hit the popular tourist island of Lombok early on Sunday, followed by a magnitude 5.4 aftershock near the city of Mataram.
Mr Kennedy had flown to Lombok where his terminally-ill 72-year-old mother, Lu Lu, lives. The pair were sleeping in the Risa Sentra Medika Hospital when the first quake struck shortly before 9am AEST.
"There was silence and then a second quake hit, which seemed shorter but more powerful," he told AAP.
"We were all evacuated out on the street in front of the hospital. Absolutely terrifying."
Mr Kennedy said he and his mother were moved into emergency rooms "which are full of people and very easy to get out if something goes wrong".
"There are still patients on the street," he added.
A spokesman for Indonesia's National Agency for Disaster Countermeasure, Sutopo Purwo Nugroho, has said the ten fatalities and injuries were caused by falling slabs of concrete.
In a statement, the Department of Foreign Affairs and Trade said no Australians were known to have been directly affected.
