Surfer's Life Hangs in the Balance After Terrifying Shark Attack

A surfer is in critical condition after being attacked by a shark off Australia's east coast. The 44-year-old man fought the shark for about 30 seconds before swimming back to shore, where a bystander applied a tourniquet. He was then transferred to the hospital with life-threatening injuries. Lighthouse Beach will be closed for 24 hours, and authorities will use a drone to monitor shark activity. An investigation into the incident has been initiated. Australia ranked second in the number of unprovoked shark encounters with humans last year.
