Overview

• Central Coast Council urged people not to touch the material and to avoid affected areas after discoveries at The Entrance, Blue Bay, Toowoon Bay, North Shelly, Shelly and Blue Lagoon, plus the Grant McBride Baths.
• The objects are grey and roughly 1–4 cm across, with officials cautioning that their composition and safety risk are not yet known.
• Environmental officers collected samples for laboratory analysis and notified the NSW Environment Protection Authority as investigations and clean‑up proceed.
• Council said the source has not been identified and noted potential origins could include stormwater, sewerage networks or shipping, with no confirmed link to previous Sydney events.
• Earlier strandings in Sydney from October to January were found to be consistent with human‑generated waste, and the EPA later identified Sydney Water’s sewage treatment network as the likely source in that separate case.
