Overview

• Central Coast Council reported grey spheres 10–40mm in size at The Entrance, Grant McBride Baths, Blue Bay, Toowoon Bay, North Shelly, Shelly and Blue Lagoon.
• Warning signs advise beachgoers not to touch the material and to avoid affected waters until further notice.
• Environmental officers have collected samples for laboratory analysis, the NSW EPA has been notified, and inspections and cleanup are underway.
• Authorities have not confirmed the composition or origin or whether these findings relate to the black balls that affected Sydney beaches from October 2024 to January 2025.
• The EPA previously identified Sydney Water’s land‑based sewage network as the likely source in the Sydney cases, and a local reported dogs became ill after ingesting material at Shelly Beach.
