UPDATE: The source of mysterious debris balls that washed ashore on New South Wales (NSW) beaches in August 2025 has been confirmed as Sydney’s wastewater system. This alarming revelation comes as beachgoers continue to express concerns over the potential health risks associated with these strange objects.
Earlier this week, council environmental officers traced the grey balls, which weigh between 10g and 40g, back to the Malabar Wastewater System operated by Sydney Water. Authorities reported multiple sightings across popular beaches, including Shelly Beach, The Entrance Beach, and North Shelly Beach.
In August, crews quickly mobilized to clean up approximately 40 kg of the debris, which was subsequently disposed of at a licensed waste facility. Despite these efforts, the incident has raised serious safety concerns, prompting officials to advise beachgoers to avoid swimming, walking, or exercising in affected areas. Pets, too, should be kept at a distance to prevent accidental ingestion of the hazardous material.
A dog owner reported their pets fell ill after consuming the debris, highlighting the potential dangers. “Went to Shelly Beach today… the dogs ate some of the waste balls and are now vomiting,” they shared online. Thankfully, they were able to get veterinary attention, but the incident underscores the urgency of addressing this environmental hazard.
The Environmental Protection Authority (EPA) is actively investigating how the wastewater leaked and polluted the beaches. They have promised to provide further updates to the public as more information becomes available.
Authorities urge anyone who encounters these debris balls to avoid touching them and to report any new sightings immediately. The situation remains fluid, with investigations ongoing, and community awareness is crucial.
As the investigation unfolds, residents and visitors to the NSW Central Coast are advised to remain vigilant and prioritize safety. Stay tuned for more updates on this developing story.
