The shark incident at Sydney beach has resulted in the closure of 20 beaches in northern Sydney till the official announcement. The decision was made by the officials after three shark encounters all over Australia were recorded in just over a day.
A man was bitten on the calf at North Steyne in Manly around 6.20 pm on Monday, and he suffered critical injuries. The incident happened just a few hours after a young surfer had his board bitten at Dee Why. Another young swimmer was in a critical condition after a shark attack in Vaucluse on Sunday afternoon. NSW Shark Smart said that all Northern Beaches are closed until further assessments are done.
The authorities also pointed out that the recent coastal weather had drastically increased the chances of shark activity. During summer and autumn, when the water temperature is above 19°C, bull sharks are more prevalent in NSW waters. Rainfall makes it more likely that sharks will interact with humans in the coastal areas, especially during late afternoons and evenings.

Critical Injuries Highlight Rising Sydney Shark Attack 2026 Risks
The injured man was pulled from the water after surf cameras caught the entire scenario, and multiple emergency crews were dispatched to the beach. Witnesses told about a hero surfer who brought the victim to shore, while beachgoers were rushing to help.
Paramedics took care of the man’s serious leg injuries and then transported him to Royal North Shore Hospital. NSW Police have stated that the man is in critical condition after being subjected to protracted CPR at the site. During the response operation, a rescue helicopter was also sent out.
The surfer who lent a hand said that as they were paddling frantically towards the shoreline, blood was already visible on the board. The lifeguards were off duty at that moment, which increased the heavy reliance on bystanders and medical professionals who were there. A nurse gave immediate first aid while the emergency services were on their way to the location.
How Are Weather Conditions Increasing Shark Encounters Australia Wide?
Authorities stated that the weather patterns along the coast, which have happened recently, were the reason for the conditions that very much upsurged the sharks’ movement close to the beaches where people were.
Shifting of the bull sharks to the shallow waters usually happens when the water temperatures are 19°C and above. Nutrient-rich water resulting from heavy rains is pushed towards the coastal areas, and thus, bait fish and, consequently, predators are attracted. Swimmers and surfers also become more exposed to the risk coming from the sharks during the afternoon and evening periods.
NSW Shark Smart has reiterated its public safety campaigns and has asked the beachgoers to stay alert even during closures. The officials are still performing visual checks on the sharks through plane patrols and active monitoring systems.

Community Response Demonstrates Swift Emergency Coordination
Before police and paramedics got there, people from the neighbourhood offered immediate first aid. Surf lifesavers managed the crowd while the helicopters were making sure that the aerial visibility was good.
Police commended the people for cooperating during the evacuation. Lifeguards used megaphones to instruct the swimmers to come out of the water after they got the report of shark sightings. Authorities are still examining the emergency response plans following the incidents.
What Happened During The Dee Why And Vaucluse Attacks?
Earlier on Monday, a shark bit a part of the surfboard of an 11-year-old boy at Dee Why, but he was not hurt. The witnesses said they noticed a bull shark that seemed to be 1.2 meters long close to the boy.
On Sunday, a kid around 12 years old was attacked by a shark while jumping on the rocks close to Shark Beach in Vaucluse at about 4.20 pm. The friends did help to get the wounded boy out of the water despite the injuries being very severe.
The double tourniquet was put on by a paramedic, which prevented the loss of a lot of blood. The boy is in critical condition after surgery atthe Children’s Hospital, Randwick.
