Le spiagge dell'est di Sydney chiudono dopo che le acque hanno lavato le carcasse di balena

Two Sydney beaches were closed on Thursday after a decomposing whale carcash washed up in a rocky cove, prompting officials to warn against swimming due to the potential presence of sharks. Authorities stated there are no immediate plans to remove the body, instead hoping that high tides will carry the carcass back out to sea. The incident occurred at Lurline Bay, a secluded area situated between Coogee and Maroubra beaches in Sydney’s eastern suburbs. Lifeguards discovered the floating animal just before 8 am on Thursday. In response, Randwick Council closed both Maroubra and Coogee beaches indefinitely and restricted public access to the surrounding rock shelves. Dr. Clare Willington, the Mayor of Randwick, explained that the closures were implemented to ensure community safety. She noted that decaying marine life can attract aquatic predators, specifically sharks. Willington urged the public to respect the restrictions, stating that the beaches would reopen as soon as conditions were deemed safe. The council has also contacted Surf Life Saving regarding the possibility of deploying additional drone patrols, although Willington clarified this was a precautionary measure since no confirmed increase in shark activity had been reported yet. The identification of the whale presents conflicting information among experts. While the council initially described the animal as a baby or juvenile humpback, whale scientist Dr. Vanessa Pirotta assessed the body as likely belonging to a young adult or teenage humpback. Due to the advanced state of decomposition, it is difficult to confirm the exact age or species with certainty. Dr. Pirotta advised the public to stay away from the water, noting that the carcass is likely to draw sharks to the area. Robert Cooley, a senior ranger with the Gamay Rangers, an Indigenous group based in La Perouse, highlighted the logistical challenges of removing the animal. He pointed out that strong north-easterly winds and ocean swell were pushing the carcass against the rocks, making it impossible to bring machinery or vessels into the bay. Cooley expressed a preference for allowing natural processes to handle the situation. He noted that in recent years, beached carcasses have sometimes been sent to landfill, a practice that caused distress within the local community. Consequently, the rangers aim to avoid such interventions whenever possible. Cooley admitted he was not fully confident that the tide would successfully move the whale, given the current weather conditions. However, he observed that if the body were carried out to sea, its advanced state of decay meant it would break down quickly in the open ocean. Cultural protocols are central to the management of the scene. The humpback whale is a significant totem animal for the local Bidjigal people. Willington acknowledged the involvement of Gamay Rangers, staff from the New South Wales Department of Primary Industries, and national parks personnel in handling the situation with cultural respect. Cooley stated that cultural advisers would be brought on-site to perform appropriate ceremonies. The carcass bears visible signs of prior human interaction. A piece of rope was found wrapped around one of the whale’s pectoral fins. According to Cooley, this debris resulted from an unsuccessful attempt on Wednesday to tow the animal further out to sea from the northern beaches near Manly. The whale was reportedly spotted in that area the day before it appeared in Lurline Bay. Health officials are monitoring the situation for avian influenza risks. Because the body is too rotten to yield reliable samples, standard H5N1 testing cannot be performed. Nevertheless, Willington emphasized that all dead animals must be treated as potentially infected with the virus. She strongly advised the community to maintain a significant distance from the carcass to minimize health risks. This event coincides with seasonal changes in local marine wildlife patterns. Bull sharks typically migrate north to Queensland during cooler months but begin returning to Sydney waters when coastal temperatures reach 19 or 20 degrees Celsius. Research indicates that these sharks are arriving earlier in October each year and remaining for approximately two weeks longer than in past decades, a trend attributed to rising water temperatures associated with climate change. Although bull sharks prefer warmer waters around 22 degrees Celsius and peak in activity during January and February, their early arrival increases the likelihood of encounters with scavengers attracted to the carcass. Similar incidents have occurred recently along the New South Wales coast. In April, a 25-tonne sperm whale washed up near Era Beach, leading to the closure of all beaches in Royal National Park due to the threat posed by scavenging sharks. Additionally, a juvenile humpback calf washed up on Greenhills Beach in the Sutherland Shire in July. That animal was tested for H5N1 and returned a negative result. Broader ecological trends suggest that such sightings may become more frequent. Emeritus Professor of Marine Ecology at Macquarie University, Robert Harcourt, noted that the humpback whale population on the east coast has recovered to an estimated 50,000 individuals. As populations grow, the probability of individuals running aground increases. Most drifting carcasses eventually float back out to sea, but those that come close to shore can strand themselves. Currently, an estimated 50,000 humpbacks are migrating south toward Antarctica after breeding in warm tropical waters near the Great Barrier Reef. Upon reaching polar regions, these whales feed heavily on krill to build up fat reserves for their subsequent migration.
