How common are tsunamis in Australia?

Tsunamis are rare events in Australia, usually only occurring once every two years and presenting little threat of land inundation to our coastal communities.

Is Australia vulnerable to tsunamis?

WHILE Australia is seen as a nation largely immune from the risks of earthquakes, experts have revealed that Australia is susceptible to a devastating tsunami. Given that more than 85 per cent of Australians live within 50km of the coast, the consequences could be devastating.

Is Sydney prone to tsunami?

Why do tsunamis not occur in Australia?

Tsunamis created by subduction zone earthquakes at these trenches have several hundred to several thousand kilometres of ocean to travel across before reaching our shores.
