What TsunamiSafe means for you

Commercial Shipping Tsunami NSW SES

Ports & Commercial Shipping


Did you know that even if you are at sea, there may still be a potential risk in the event a Tsunami Warning is issued. Below are some tips to remember when at sea, and a Tsunami Warning is current.

Marine Rescue NSW will be authorised to disseminate warnings to commercial shipping and Ports in the event of a Tsunami Warning being issued.



You may be in an area where an official warning will not be available, so you should be aware of the natural warning signs that a tsunami is approaching.

  • You may see the ocean drop. As tsunami approach the shoreline, the sea level may, but not always recede or drop dramatically before returning as a fast moving series of waves.
  • You may hear an unusual roaring sound from the ocean before the arrival of a tsunami.

Actions to take when a Tsunami Warning is issued

  • Boats in harbours, estuaries and in shallow coastal water should return to shore. Secure your boat and move away from the waterfront
  • Vessels already at sea should stay offshore in deep water until further advised

  • Check that other shipping have received this advice
  • Keep listening to your local radio station and emergency broadcast channels for updates and advice
