FROM NORTHERN BEACHES COUNCIL:
Nine Beaches in the Northern Beaches are closed after white/grey, ball-shaped debris was found washed up along the shore.
Council was alerted to the debris via the EPA and is working closely with the state agency to collect samples for testing.
So far, most samples identified are marble-sized with a few larger in size.
The Council is organising the safe removal of the matter and is inspecting other beaches.
Beachgoers are advised to avoid Manly, Dee Why, Long Reef, Queenscliff, Freshwater, North and South Curl Curl, North Steyne and North Narrabeen beaches until further notice and keep away from the material while the clean-up and investigations continue.
Anyone who notices this kind of debris on other beaches is encouraged to contact Northern Beaches Council on 1300 434 434.
