Fourth shark attack in three days rocks Australia as authorities close beaches and deploy drumlines

A surge in shark attacks in New South Wales, Australia, has prompted beach closures and the deployment of shark-detecting drumlines. Four shark attacks occurred in three days, including one on Tuesday where a surfer sustained minor injuries near Point Plomer. Other incidents include critical injuries to a man and a boy in separate attacks near Sydney on Sunday and Monday, and another boy escaping unharmed after a shark bit his surfboard. Authorities believe bull sharks are likely responsible, with murky water conditions due to recent rainfall potentially contributing to the increased shark activity. Beaches along the northern coast of New South Wales and in northern Sydney will be closed for at least 48 hours.
