A 39-year-old man was killed after being attacked by a shark while spearfishing near Kennedy Shoal on Sunday. The incident took place approximately 45 km off the coast of Queensland as the man was diving with friends from a boat. Emergency services arrived at the scene, but he succumbed to serious injuries shortly after reaching shore, according to BBC, Al Jazeera, and Channel News Asia.

The man sustained what police called a "critical head injury" during the attack. Witnesses reported the incident was shocking, with one friend who pulled him from the water being traumatized by the experience. Police are working to identify the shark species involved in the attack, which remains unknown, as per statements from authorities including Reuters and CBS News.

This incident follows another fatal shark attack on May 16, when a 38-year-old man was killed near Perth, bringing the total fatalities from shark attacks in Australia to two within a week. Generally, about 20 shark attacks are reported in Australia annually, but most do not result in fatalities, according to sources including CBS News and Reuters.
