Despite Australia’s relatively low frequency of tsunami events, the impact of such incidents can be devastating, making awareness and preparation essential.  

According to the Bureau of Meteorology, Australia has had more than 50 tsunami events since 1788. While onshore tsunamis are rare, coastal areas are regularly affected by marine threat tsunamis, which can generate dangerous rips, waves, and strong currents.  

NSW SES Director of Emergency Management Melissa Daley said it was important the community talk about their risks and what to do to prepare for all natural hazards.   

“When Australians think of tsunamis, they often recall the tragic events in Indonesia and Japan. However, it’s crucial for coastal residents to understand they are at risk of tsunamis,” Mrs Daley said. 

“We know marine threat warnings are issued from time to time, and people should know what to do. In the event of a marine or foreshore threat, the community should move away from the beaches and estuaries, and boats should return to moorings or stay in water 25 metres deep.  

“In a land threat tsunami, people should move at least one kilometre inland or if unable, 10 metres above sea level on higher ground and take only essential items and evacuate on foot, as roads may be congested or closed. If you cannot reach higher ground, seek shelter in the upper story of a sturdy building.”  

While the NSW SES is the lead agency for tsunamis, the Service collaborates with local councils, Surf Life Saving, and Marine Rescue to ensure a coordinated response.   

To mark World Tsunami Awareness Day, NSW SES members will host community engagement events along the east coast, providing an opportunity for locals to have a chat about their tsunami risk.  

The events being held will offer Evacuation Area map reading and opportunities to learn about tsunamis. Some units will have Paddy the Platypus visit and pose for photos. While some units will offer a complimentary community BBQ.
