BREAKING: Authorities have identified the source of the mysterious grey balls that washed up on beaches along the NSW Central Coast. Samples confirmed these debris balls, which range from 10g to 40g, originated from the Malabar Wastewater System in Sydney.
The alarming discovery was made earlier this year, when environmental officers reported the presence of the balls at multiple locations, including The Entrance Beach, Grant McBride Baths, and Shelly Beach. Sydney Water is currently investigating how this wastewater debris leaked and polluted these popular beaches.
In August 2025, local councils launched immediate clean-up operations, successfully removing approximately 40kg of debris which was disposed of at a licensed facility. Beachgoers were warned to avoid swimming, walking, or exercising at affected locations. Authorities also advised pet owners to keep their animals away from the debris due to potential health risks.
One dog owner reported a concerning incident after their pets ingested the balls. They shared online, “Went to Shelly Beach today… dogs ate some of the waste balls and are now vomiting.” Thankfully, the pets have been treated and are being monitored at home.
Officials from the Environmental Protection Authority (EPA) have pledged to provide further updates as more information becomes available. Residents and beachgoers are urged to report any sightings of new debris to their local council immediately.
This incident raises significant public health concerns, and the community is advised to remain vigilant while authorities continue their investigation. Stay tuned for more updates on this developing story.
