A 12-year-old boy has died in hospital after being mauled by a shark while swimming in Sydney Harbour, marking one of several recent shark attacks along Australia’s eastern coastline that have raised serious public safety concerns.
The victim, Nico Antic, was attacked on January 18 while jumping into the water with friends. Authorities believe the attack was carried out by a bull shark. Despite the swift and courageous efforts of his friends, who leapt into the water to rescue him, Nico sustained severe injuries to his leg.
He was rushed in critical condition to Sydney Children’s Hospital, where he underwent emergency surgery and was placed in a coma. Tragically, he succumbed to his injuries shortly afterward.
In a statement, Nico’s parents, Lorena and Juan, said they were “deeply heartbroken” by the loss of their son. They described Nico as a cheerful, friendly boy with a kind and generous heart. “He was full of life, and that is how we will always remember him,” the family said. Originally from Argentina, the family has received an outpouring of support, with an online fundraising campaign raising nearly USD 240,000 (approximately GBP 121,000) to assist them during this devastating time.
Nico’s death is one of four shark attacks reported along the New South Wales coast within just two days. Last week alone, three shark-related incidents occurred in Sydney. On Monday, a surfer narrowly escaped a shark attack in the city’s Northern Beaches area. Hours later, a 27-year-old man was seriously injured in another attack at a nearby beach. The following day, a 39-year-old man suffered chest injuries after being bitten by a shark on the Mid North Coast of New South Wales and was hospitalized.
Why Are Shark Attacks Increasing in Australia?
Experts attribute the recent surge in shark attacks along Australia’s east coast to environmental factors rather than an increase in shark populations or aggressive behavior.
Marine scientists explain that shark attacks are more likely when environmental conditions are favorable—particularly when heavy rainfall alters coastal waters. Recent downpours have caused seawater to become murky and less saline, creating ideal conditions for bull sharks, which thrive in warm, low-salinity environments.
Sydney recorded 127 millimeters of rain within a 24-hour period in the days preceding the latest attacks. This influx of freshwater, experts say, likely carried nutrient-rich runoff into the ocean, attracting bait fish closer to shore—and with them, sharks.
Dr. Rebecca Olive, Senior Research Fellow at RMIT University, told the BBC that bull sharks are uniquely suited to such conditions. “Bull sharks do well in warm, less salty water where many other sharks cannot survive. They are comfortable in river mouths and murky environments, so the recent heavy rainfall has created ideal conditions for them,” she said.
Similarly, University of Sydney expert Chris Pepin-Neff described the phenomenon as a “perfect storm.” “The low-salinity freshwater has triggered a kind of biodiversity explosion. Bait fish rise to the surface, bull sharks follow, and humans are present in the same space—this is where the risk emerges,” he explained.
In response to safety concerns, several Sydney beaches were temporarily closed. Many have since reopened as weather conditions improved ahead of the long Australia Day holiday weekend. Authorities, however, continue to urge caution, emphasizing that the recent attacks are linked to environmental changes rather than a long-term increase in shark numbers.
