Recent shark attacks may be linked less to shark behaviour – and more to the pollutants, pesticides and parasites humans send into the ocean.

Swimmers in Sydney have been urged to stay out of the water after three people were seriously wounded during a spate of shark attacks in New South Wales.

If greater active risk mitigation steps are not taken and shark numbers not responsibly reduced, many more people will be mauled and killed.

A man who was attacked by a bull shark at Manly would have likely died without critical units of blood he received following a swift, 10-second handover between police and paramedics likened to “F1 pit stop” on a Sydney bridge.

A 39-year-old man has been rushed to hospital after a shark attack on NSW’s Mid North Coast. The incident is the fourth shark attack in the state in the past 48 hours.

Swimmers are being encouraged to stay 'shark smart' after four recent attacks, as attention turns to safety measures designed to control the apex predators.

Only a few hours earlier, a shark knocked an 11-year-old boy into the water at Dee Why—just north of Manly—and bit a chunk out of his surfboard. And on Sunday afternoon, a 12-year-old boy was bitten by what authorities believe was a bull shark while swimming at a popular beach in Sydney Harbor. He is still in a critical condition in hospital.
