Australian authorities have announced that a woman died and a man was seriously injured on Wednesday in a shark attack on a beach near a popular surfing spot on Australia's east coast. New South Wales police said emergency services were dispatched to a beach at Coffs Harbour, about 350 kilometers north of Sydney, following reports of a shark attack on two people. The woman, believed to be in her 20s and whose identity has not yet been officially confirmed, was pronounced dead at the scene. The man, also believed to be in his 20s, was airlifted to a hospital in critical condition. Officials said the beach has been closed while authorities attempt to determine the species of the shark.
