Central News Agency (CNA Sydney, July 3, Comprehensive Foreign News) Australian authorities in New South Wales launched a large-scale drone patrol program on July 1 to protect beachgoers from shark attacks. According to data obtained by Agence France-Presse today, a total of 73 shark sightings were recorded at various beaches in the capital, Sydney, within two days, leading to the closure of multiple beaches. There have been several shark attack incidents in Sydney and other parts of New South Wales recently. First, in September last year, a surfer was killed in a shark attack at a beach north of Sydney. In January this year, a child was bitten and killed by a shark in Sydney Harbour. In June, a woman was injured by a shark at the popular Coogee Beach. This program only tracks shark species considered most likely to attack humans, such as bull sharks, tiger sharks, and great white sharks. Lifeguards stated that as sharks move in the water, some sharks seen during patrols might be recorded multiple times. However, on July 1, a group of 13 sharks swimming together was reported at a beach in South Narrabeen, Sydney. Drones spotted sharks three times at Dee Why Beach yesterday and once again this morning, causing the beach to be closed for an hour before reopening, but it was subsequently closed again. New South Wales Premier Chris Minns stated on June 28 that as this world's largest drone monitoring program is being intensified, swimmers and surfers will likely have to get used to coming ashore when instructed.
