Mysterious Waste Balls Wash Up on Sydney's Silver Beach

Authorities are investigating debris made of human and industrial waste that has appeared on Sydney beaches for the second time in two months.

Ball-shaped debris of various sizes and colors, including black, grey, and green, was discovered on Silver Beach in Kurnell, prompting a cleanup and public warnings.
The New South Wales EPA has collected samples for analysis to determine the source, following similar incidents on Sydney's eastern beaches in October.
Initial findings suggest the debris, described as 'fatbergs,' is composed of human waste, cooking oils, motor oil, and other pollutants typically found in sewers.
Authorities have not identified the origin of the waste, with theories ranging from damaged sewer systems to illegal discharges from boats.
The Sutherland Shire Council is monitoring nearby beaches for further contamination as cleanup efforts continue, with residents urged to avoid affected areas.
