A series of distinct events involving shark activity and a whale carcass occurred along the coast of New South Wales, Australia, in late January. The events include multiple shark bites, the death of a 12-year-old boy, and a large-scale whale carcass removal operation.
Tribute for Fatal Shark Attack Victim
A paddle-out tribute was held in North Bondi for 12-year-old Nico Antic. The event was organized by his school, Rose Bay Secondary College, and was attended by hundreds of people, including family, friends, and local surf lifesavers.
Overview of Shark Bite Incidents
Multiple shark bite incidents were reported along the New South Wales coast. The events occurred in Sydney's eastern suburbs, the Northern Beaches, and the Mid North Coast.
Vaucluse (Sydney Harbour): On Sunday, January 18, at approximately 4:20 PM, a 12-year-old boy, identified as North Bondi surf lifesaving nipper Nico Antic, was bitten on the leg while jumping from a rock ledge near Shark Beach, Nielsen Park. Bystanders applied a tourniquet. The boy was transported by police boat to Rose Bay, treated by paramedics, and taken to Sydney Children's Hospital, Randwick, in critical condition. He died in hospital almost a week later. His parents, Lorena and Juan, released a statement expressing their sorrow and thanking first responders. Authorities believe a bull shark was involved.
Dee Why Beach: On Monday, January 19, an 11-year-old surfer's surfboard was bitten by a shark. The surfer was uninjured.
North Steyne Beach, Manly: On Monday, January 19, at approximately 6:20 PM, a 27-year-old man, later identified as Andre de Ruyter, sustained critical leg injuries from a shark bite while surfing. He was hospitalized in critical condition.
Point Plomer, Mid North Coast: On Tuesday, January 20, at approximately 9:00-10:00 AM, a 39-year-old surfer, Paul Zvirzdinas, was bitten on his surfboard and wetsuit near the Point Plomer campground. He sustained minor cuts and grazes and was transported to Kempsey District Hospital in stable condition. A shark, believed to be a bull shark, also reportedly circled his nephew and brother-in-law.
Beach Closures and Warnings
Following the series of incidents, several beaches were closed to the public.
- All beaches in Sydney's Northern Beaches area were closed for 48 hours following the attack at Manly.
- Beaches from Town Beach in Port Macquarie to Crescent Head were closed after the Point Plomer incident.
- Shark Beach in Vaucluse was closed.
- Surf Life Saving NSW advised the public to avoid swimming or surfing near river mouths and in murky water.
- Authorities advised against swimming in Sydney Harbour for approximately 72 hours after a major storm.
Environmental Factors
Experts and authorities have cited several environmental conditions as potential contributing factors to the increased shark activity.
- Heavy rainfall preceded the incidents. Sydney recorded 127mm of rain in 24 hours, marking its wettest January day in 38 years. The freshwater runoff created low-visibility, brackish water conditions favored by bull sharks.
- The runoff carried sewage and nutrients into the ocean and harbour. This is thought to have attracted bait fish, which in turn attracted larger predators like sharks.
- The combination of brackish water, freshwater runoff, and splashing during the Vaucluse attack was described by a police official as a "perfect storm environment."
- Scientists have noted that bull sharks now arrive in Sydney Harbour approximately a month earlier (in October) and remain longer (until May), a change attributed to climate change.
Experts' Views on Shark Culling and Management
Experts provided commentary on the management of shark-related risks and specifically addressed calls for shark culls.
- Shark Culls: Researchers stated that scientific evidence does not support shark culls as an effective method for reducing the risk of incidents. They argued that removing sharks in one area does not eliminate the risk if the attractants (e.g., nutrients from runoff) persist. Environmental groups voiced concerns about resuming culls, with one group in New Caledonia filing a legal challenge against a decision to resume culling after a fatal attack. Shark behavior experts have proposed alternative strategies, such as identifying and removing specific "problem sharks" using DNA analysis.
- General Advice: Experts and authorities recommended "shark smart" behavior, which includes avoiding swimming in murky water, after heavy rain, and at dawn, dusk, and night. They also advised swimming in netted enclosures, particularly in harbours and estuaries during summer and autumn. Some individuals, including a former police diver, recommended against swimming in open harbour waters entirely.
- Incident Trends: Researchers noted that while the number of recorded shark bite incidents in Australia has increased over the last 30 years, this is attributed to improved data collection, population growth, and increased participation in water sports. They stated that incidents and fatalities remain relatively uncommon.
Whale Carcass Removal
A separate incident involved the stranding and removal of a sperm whale carcass.
A sperm whale carcass, estimated to weigh between 20 and 25 tonnes, was discovered on rocks at Era Beach in the Royal National Park on Sunday. Due to the remote location and lack of vehicle access, the removal operation was delayed. On Anzac Day, the carcass was towed 20 to 30 km south to Bellambi Beach. It was then lifted from the water and transported to a waste facility in Wollongong.
Radioactive decay: The carcass attracted a significant number of sharks. Surf Life Saving Illawarra reported that seven sharks were sighted between Woonona and East Corrimal, leading to the evacuation of swimmers. A drone was used for surveillance. Garie, Wattamolla, Era, and Burning Palms beaches were closed due to increased shark activity. The public was advised to stay out of the water for at least 48 to 72 hours due to ongoing shark activity.
The NSW National Parks and Wildlife Service coordinated the removal, which was described as one of the most challenging operations due to the carcass's size, weight, stage of decomposition, and location. Indigenous groups were consulted for a culturally sensitive removal ceremony.
