Shark watch: Intelligent buoys boost protection

Swimmers off the Australian coast are enjoying safer seas in the knowledge that Fendercare Marine's hi-tech buoys are keeping track of shark movements in the area.

Fendercare Marine Australia has been closely involved with the Australian Government’s ‘shark watch’ programme since 2008 but it recently landed a deal to supply dozens of  “shark monitoring buoys” in New South Wales – bringing the total of 71 buoys supplied in Australia’s coastal areas so far.

Each buoy is fitted with electronics and attached to a specially built leg which extends 4.5m below the surface to pick up any signals transmitted by tagged sharks.

The buoys, anchored at intervals 500-700m off the coast in populated areas, beaches and surf breaks, provide early warnings of shark activity and so offer increased protection for bathers.
