A 23-year-old surfer was attacked by a shark at North Shore Beach near Port Macquarie on the East Coast, marking the third shark attack in Australia this month.

The victim of the shark attack sustained leg injuries, which are considered non-life-threatening, and is currently receiving treatment at the scene.

Following the sighting of a Great White Shark in the region, beaches near Port Macquarie have been closed for at least 24 hours.

Multiple ambulance crews and a rescue helicopter have been dispatched to North Shore Beach to respond to the shark attack.

Onlookers at the beach provided initial first aid to the victim's severe leg injuries before emergency services arrived.

A retired police officer used a dog leash as a tourniquet to save the victim's life by stemming the bleeding from the shark attack.

The Department of Primary Industries and Regional Development is collaborating with local authorities to coordinate safety measures and keep the public informed about the shark incident.

Despite recent shark incidents, Australian beaches remain popular for swimming and water activities.

Emergency services responded to the shark attack at around 11 am on a Tuesday.

In the past year, Australia had about a dozen shark attacks with injuries and four fatalities, while this year has already seen over half a dozen non-fatal attacks.
