Sydney is in full panic after three shark attacks tore through the city in barely a day, leaving a child fighting for his life, a surfer mauled, and families fleeing beaches that were packed just hours earlier.

Officials say the cluster is “unprecedented.” Locals have a simpler word for it: terrifying.

The horror started Sunday at Shark Beach — a spot tourists love and locals trust.

A group of kids were leaping off a rock ledge, laughing, splashing, filming videos. Then the water turned red.

A massive shark — believed to be a bull shark, one of the most violent predators in the ocean — grabbed a 12-year-old boy and dragged him under.

His friends pulled him out while screaming for help.

“It was a horrendous scene,” said Marine Commander Joseph McNulty. “These boys saw injuries no kid should ever see. Their courage was gallant. They saved his life.”

Police officers found the boy fading fast, with catastrophic wounds to his legs. They fought to keep him alive on a speeding police boat, applying tourniquets and performing resuscitation while racing toward paramedics.

He is now in intensive care, clinging to life.

McNulty said the attack happened during “perfect storm conditions” — murky water, heavy runoff, and sharks hunting close to shore.

Monday morning brought no relief.

An 11-year-old surfer at Dee Why Beach was knocked off his board when a shark slammed into it, tearing chunks from the foam. Witnesses say the board looked “like something took a bite out of a sandwich.”

The child was rushed away as officials begged swimmers to clear the water.

Then came the third hit.

Just after 6 p.m., a surfer at Manly’s North Steyne Beach was dragged from the surf with severe leg wounds. The water around him was red.

One witness said, “People were screaming. Everyone ran. I’ve never seen anything like it.”

Police immediately shut down every beach in Sydney’s Northern Beaches district — an extraordinary move not seen in years.

Australia already has a reputation for brutal shark encounters. Five people were killed last year alone.

But three attacks in one city in one day? Locals are calling it a “bad omen.”

Marine experts say bull sharks love murky, shallow water. And when storms push prey closer to land, sharks follow.

“It’s the overlap we fear,” said marine biologist Dr. Rowan Hughes. “Humans and sharks in the same hunting zone.”

Tourists are rattled. Residents are spooked.

“I’m done with the ocean until further notice,” said an American visiting Manly. “I’ve never seen a beach shut down like this. It feels like the sharks are circling.”

Police are now using drones, boats, and helicopters to hunt for sharks along the coastline.

Meanwhile, the city waits — and worries.

“You can’t ignore this,” said a local father watching from behind police tape. “Three attacks in a day? Something is off out there.”
