Authorities have issued a temporary ban on visitors to nine beaches in Sydney, Australia. The decision was taken on Tuesday (January 14) as an early warning when some unknown objects like small white and gray balls washed up on the beach with the waves of the sea. British news agency Reuters reported this.
The Northern Beaches Council said in a statement that most of the unidentified objects were marble-shaped. Some, however, are slightly larger in size. Efforts have been made to move them safely.
Last October, thousands of black balls washed up on several beaches, including Sydney's Bondi. Tests by authorities later showed they contained a mixture of fatty acids, chemicals used in cosmetics and cleaning products, hair, food waste and other substances associated with wastewater.
Tourists from all over the world flock to Sydney's beaches for its golden sands and blue waters. Now it was summer vacation, so there was a lot of visitors.
Authorities said they are working with the state environment department to collect and analyze the mysterious objects. Beachgoers are advised to avoid Manly, Dee Howe, Long Reef, Queenscliff, Freshwater, North Carl Carl, South Carl Carl, North Steyny and North Narrabeen beaches until further notice.
