While the overall risk of a shark attack remains low, experts say warmer waters, various weather events, shifting prey and busier coastlines can increase the risk

A recent cluster of shark attacks along Australia’s east coast – including a fatal attack on a 12-year-old boy in Sydney – has renewed attention on how people share the ocean with sharks, particularly in a country that sees more than 500 million coastal visits by beachgoers each year.
