There have been no reports of damage so far and the Joint Australian Tsunami Warning Centre says there is no threat of tsunami.
Geoscience Australia seismologist Hugh Glanville told ABC Radio Adelaide it was the largest earthquake in the state in 10 years.
“It is possible for minor damage from a magnitude-4 but it’s reasonably unlikely for this earthquake,” he said.
