A powerful 7.7 earthquake has struck a region in Indonesia, with reports the tremors were felt in northern Australia.
The quake impacted Tanimbar region early on Tuesday, the European Mediterranean Seismological Centre (EMSC) said.
There is no tsunami threat to Australia but reports on social media say tremors were felt in Darwin in the Northern Territory, about 1800km from the Tanimbar province.
"I'm in Palmerston, NT, … felt the earthquake," one witness said.
Darwin 9News reporter Olivana Lathouris said residents were woken by the after shocks early this morning but no injuries have been reported.
The quake was at a depth of 97kms below the Earth's surface, EMSC said.
This is a developing story … more to come.
