Shark control equipment

Nets

Nets do not prevent sharks from entering a particular area. They’re intended to catch 'resident sharks' and sharks that pass through the area while feeding on bait fish.

Equipment is installed far enough offshore to prevent human and shark interaction.

The Shark Control Program’s (SCP) large mesh nets are designed to catch sharks over 2 m in length. The SCP aims to reduce the number of potentially dangerous sharks in particular areas rather than create an impenetrable barrier against shark attack.

Fisheries Queensland’s net specifications and are 186 m long, a depth of 6 m, and a mesh size of 500 mm.

The nets are set adjacent to the shoreline according to the prevailing tides and currents. The topographical features of the area and sea conditions determine the nets distance from the shore.

Drumlines

Drumlines catch actively feeding sharks using only fresh, natural bait attached to shark fishing hooks suspended from a large plastic float, which is anchored to the sea bed.

Equipment maintenance

SCP equipment is serviced every second day by independent contractors who work under Queensland Boating and Fisheries Patrol supervision, weather permitting.

All fishing equipment is removed from the water for maintenance and replaced with fresh equipment at least once every 21 days.

Contractors also assist with collaborative research projects associated with the SCP and provide a 24-hour, seven-day service in case of emergency. Regular reviews are performed on contractor procedures and performance.
