- Sperm whale carcass estimated at 25 tonnes rests on a rock shelf at Era beach in the Royal National Park, decomposing and emitting a pungent odour detectable in the water and air.
- NSW National Parks and Wildlife Service (NPWS) issued a safety alert warning of an 'elevated shark risk' due to the carcass, leading to the closure of multiple beaches including Garie, Wattamolla, and Burning Palms.
- Surf Life Saving New South Wales reported a shark sighting at Era beach at 9.28am on Saturday, prompting immediate beach closures that remained in place as of Wednesday.
- Dr Vanessa Pirotta, a Sydney-based whale scientist, stated the whale likely died at sea weeks earlier, with its lower half lost to decomposition or scavengers before washing ashore.
- NPWS confirmed the advanced decomposition level prevents investigation into the whale’s cause of death, complicating any decision on removal.
- Local hikers and residents, including Garie beach shack community members, have expressed morbid curiosity or distaste, with some noting the bravery of swimming nearby despite shark presence.
Why it matters: The carcass poses immediate public safety risks due to shark activity and difficult access, forcing beach closures in a popular national park. With decomposition ruling out a cause-of-death analysis, authorities face pressure to remove a 25-tonne hazard without clear protocols, affecting both visitor safety and ecological monitoring.
