Is "Australia doesn't experience earthquakes" true?
Geography class made Australia sound seismically boring: middle of a plate, nowhere near New Zealand's chaos, so no earthquakes to worry about. That plate-boundary story is half true and got flattened into something false. Australia still gets intraplate quakes from stress building inside the continent, less often than Japan or NZ, but often enough that people feel them and cities can take real damage. Newcastle in 1989 made that impossible to shrug off.

Australia doesn't experience earthquakes
What we know now
Australia does experience earthquakes. It sits in a stable continental region of the Australian Plate, so quakes are less frequent than at plate boundaries, but intraplate faults still rupture. Geoscience Australia records on average about 100 earthquakes of magnitude 3 or more each year. Notable events include the 14 October 1968 Meckering quake (magnitude 6.5), the 1988 Tennant Creek sequence (up to magnitude 6.6, Australia's largest recorded), and the 28 December 1989 Newcastle earthquake (about magnitude 5.6), which killed 13 people and damaged tens of thousands of buildings.
Was "Australia doesn't experience earthquakes" taught in school?
Yes — and not as a joke question on a quiz. This geography claim showed up in textbooks, worksheets, and classroom posters through the 1980s, which is why so many people still remember it as settled fact long after the science moved on.

When was this understanding updated?
The evidence had largely shifted by around 1989. Schools don't flip overnight, though — plenty of classrooms kept teaching the older version for years after researchers had already moved on.
