Shark attacks are rising in Australia. Technology is helping stop them.


Australia is a nation of beaches. But a growing incidence of shark attacks is forcing authorities to turn to drones and artificial intelligence to try to keep beachgoers safe.

The incident and a deadly attack in Perth’s Swan River a year earlier have stirred fears that warmer waters caused by climate change are making sharks in some locations, just as increasing temperatures and populations drive more people to the ocean. Nets give beachgoers false security, making politicians reluctant to get rid of them, said Chris Pepin-Neff, an expert on the public policy of shark attack prevention. The new drumlines were first implemented in New South Wales in 2015, after four shark attacks — one fatal — in as many weeks sparked fear in the normally laid-back surfer communities near Byron Bay, north of Coffs Harbour.
