9.5 Shark Incidents

Purpose

To recognise and reduce risks associated with sharks, and the role of lifesaving services in managing an environment that sharks inhabit.

Overview

SLSSA requires lifesaving services to follow the provided guidelines regarding shark sightings/incidents.

Procedure

This procedure applies to shark sightings by member of public, lifesaving service and the State Fixed Wing Aircraft.

Sighting or evacuation siren sounded within 500m of a patrolled/flagged area

• Activate the Emergency Evacuation Alarm (continuous tone from either Fixed Shark Siren or handheld Loudhailer / Megaphone) and raise the red and white quartered flag.
• Inform everyone that the water is being evacuated due to a shark sighting and strongly recommend they leave the water.
• Lower the red and yellow patrol flags and, if available, display Shark Warning sign.
• Document the specific location targeted by the Fixed Wing’s circular path (i.e., the centre of its flight trajectory) and the time its siren commenced.
• Continually monitor all areas.
• Maintain minimum personnel, qualification and equipment requirements.
• Maintain an active presence on the beach to advise/warn public.
• Wherever possible monitor all areas from an elevated position (i.e. tower, jetty, patrol room etc.).
• Contact the State Operations Centre (SOC) to:
  • inform them of the shark sighting and status of patrolled area (i.e. closed); and
  • determine if additional State assets (WP1, JRB or RPAS) are available to search the area.

Sighting or evacuation siren sounded greater than 500m of a patrolled/flagged area or over a populated section of SLSC service area

• Contact the SOC and inform them of the shark siren and request additional information (Note: the Fixed Wing aircraft will provide shark sighting details to SAPOL which will be relayed to the SOC, which may be several minutes and is subject to Fixed Wing aircraft call times);
• Monitor the flight path of the aircraft and if it moves toward the patrolled area – and comes within 500m - while sounding its siren, commence evacuation of the beach (as detailed above).
• If the Fixed Wing is sounding over a populated section of your area of responsibility, dispatch a roving patrol to evacuate that section of the beach. Advise any swimmers that a shark has been sighted by the Fixed Wing aircraft and recommend that all person’s swim between the flags.

When the Fixed Wing ceases its siren and/or departs the area

• Note the time that the siren ceased, and the aircraft departed your area.
• The patrol flags should remain lowered until:
  • There has been no sighting for a minimum of 60 minutes; and/or
  • A visual clearance has been completed from the shoreline, and the Patrol Captain / Lifeguard / Safety Emergency Management Coordinator / Referee is confident that there is no obvious risk posed by the shark to swimmers / surfers / beach-users.
• Contact the SOC and inform them when the siren ceased, when the fixed wing departed and the status of patrolled area (i.e. open).
