Surf Life Saving (SLS) has over 37,500 active members and more than 1,000 lifeguards around Australia. They are based at more than 400 Surf Life Saving Clubs.

SLS works closely with council lifeguard services in managing Australia's beaches. SLS is the authority on beach management should a tsunami occur on the Australian coastline. SLS has the capacity to assist by:
Below are the delegated State Emergency Authorities (SEA) in each state/territory:
The SEA in each state/territory will have the overall responsibility of coordinating and managing the response to a tsunami warning. The SEA may also delegate particular responsibilities to SLS, such as warning the community or assisting in rescue and recovery. It is important that SLS should act upon its Tsunami Response Plan (for more information see Surf Life Saving response) only after it has been asked to do so by the relevant SEA. It is not SLS's responsibility to determine if a tsunami warning should be issued or not, with subsequent plans put in place.
The Bureau of Meteorology (the Bureau) is the delegated authority to issue a tsunami warning. The SEA then determines what level of response should be taken by relevant authorities, such as SLS.
Important:
According to the Tsunami Response Plan, the Area Director of Lifesaving is
responsible for starting or ending all actions taken by a lifesaving service.
If you, as a lifesaving service member/employee, hear of a tsunami warning
in the media, confirm with your direct supervisor
before beginning a surf lifesaving action plan.
However, where television, radio or the like is providing instructions on general
public safety, please follow accordingly.
