The man, who is believed to be in his 20s, suffered a significant injury to his arm when he was attacked by the shark Sunday off Shelly and Emerald beaches in Coffs Harbour, about 330 miles north of Sydney, CNN reported.

"A number of local surfers and bystanders came to the aid of this man," New South Wales ambulance official Chris Wilson told the outlet. "Despite the best efforts of bystanders, paramedics and other emergency services, the patient couldn’t be revived."
