A group of friends sprang into action, diving into the water to rescue a young boy named Nico after he sustained severe leg injuries. Despite their efforts, Nico was rushed to the hospital in critical condition.

In a heartfelt statement, Nico’s parents, Lorena and Juan, expressed their deep sorrow over the tragic loss of their son.

“We are devastated to announce that our beloved son, Nico, has passed away,” the family shared.

They described Nico as a joyful, sociable, and athletic young boy who possessed a remarkably kind and generous nature.

“He was always brimming with life, and that vibrant spirit is how we will forever remember him,” they added.

“We would like to sincerely thank the first responders and the teams at Sydney Children’s Hospital, Randwick for everything they did to care for Nico.

“We would also like to thank everyone in the community for their support and kind messages.

“We ask you please respect our privacy during this exceptionally difficult time.”

String of shark attacks 

Nico, a junior lifesaver, was the first of four shark attack victims in 48 hours on NSW beaches this week after a weekend of wild weather.

He was pulled to shore by fellow surfers and remains in a critical condition, with part of his lower right leg amputated.

Hours early at nearby Dee Why Beach on the northern beaches an 11-year-old surfer had his board bitten by a shark.

The whole stretch of beaches were closed.

He only suffered minor injuries and has since been discharged from hospital.

Heavy rain means more fresh water than usual is running through rivers and estuaries into saltwater systems and beaches, creating brackish water.

This is a phenomenon where fresh and saltwater mix, being saltier than normal freshwater, but less salty than typical seawater.

“Bull sharks are also one of the few species of sharks and rays that can tolerate brackish and even freshwater for extended periods,” Professor Jodie Rummer from James Cook University said.

“Which means they are especially comfortable moving in and out of river mouths and turbid coastal waters after heavy rain.”
