Authorities in Western Australia have closed popular snorkelling spots at Ningaloo Reef, including Oyster Stacks and North Mandu, following the death of a humpback whale. The carcass, which washed into the shallows, has attracted a significant number of sharks, prompting officials to issue a safety alert that may remain in place for weeks.
The incident is part of a concerning trend, with the Department of Biodiversity, Conservation and Attractions (DBCA) reporting five whale entanglements in just five days. While one whale was successfully freed, the animal involved in the current beach closures died despite rescue efforts. Three other whales remain unaccounted for following air and sea searches.
Local experts and wildlife advocates are calling for an immediate investigation into the source of the entanglement risks. Brinkley Davies of the Baloo Blue Foundation noted that the ropes found on the animals are consistent with commercial fishing gear, such as crab and cray pots. Marine mammal ecologist Dr. Kate Sprogis suggested that whales may be dragging these lines for hundreds of kilometres from southern fishing grounds before reaching the reef.
DBCA Exmouth marine program coordinator Sam Miles urged the public to report sightings of entangled whales immediately rather than attempting to intervene. “If people cut off those ropes and floats, it becomes extremely difficult for us to locate the animal,” Miles stated. The region is currently experiencing peak tourism during school holidays, making the closure of these iconic marine sites a significant disruption.
