Seismicity in Australia
Earthquakes can occur in almost every part of Australia, although certain regions have a higher likelihood of experiencing an earthquake than others. Possibly the most earthquake prone regions of Australia are the West Australian wheatbelt, and the Flinders Ranges of South Australia. The alpine region of eastern Australia is also relatively active. Three Australian earthquakes are known to have caused fatalities. The 1902 earthquake near Warooka, on the Yorke Peninsula of South Australia (mag 6.0), caused two deaths, attributed to heart attacks. The 1935 Gayndah earthquake in Queensland caused one death. By far the most significant was the 1989 earthquake at Newcastle, NSW (mag 5.6), which caused 13 fatalities, mostly because of the catastrophic structural collapse of the Newcastle Worker’s Club.
West Australian seismicity is treated separately on this site. Seismicity for the rest of Australia is summarised below.

This map shows that the coastal regions of NW Australia are the most earthquake prone, and the region of east Australia to the west of the dividing range is the least.

Although the Newcastle NSW earthquake of December 1989 was one of our most significant in terms of loss of life and damage, for sheer energy release, the activity which began in Tennant Creek, NT in January 1988, is probably more significant. Three magnitude 6 events occurred there within 24 hours, and complex surface rupturing occurred. Many thousands of aftershocks have occurred there since those events, and aftershocks are still occurring there.
Since the Tennant Creek earthquakes, the largest Australian event has been the Mag 6.3 event off Cockatoo Is., northern WA, in August 1997.
Between 2000 and 2002, a large swarm of earthquakes occurred near Burakin, WA. Burakin is approximately 200 km NE of Perth. Three earthquakes of magnitude 5.0 or more occurred in this earthquake swarm.
Since the 1997 Cockatoo Is. event, the largest Australian earthquake has been the magnitude 5.4 earthquake at Mt. Redvers, N.T., near the West Australian border. It occurred on Feb 11 2004.
