Sydney’s Northern Beaches council says it has reopened seven of the nine beaches that were closed to the public after marble-sized “grease balls” washed ashore.

Queenscliff, Freshwater, North Curl Curl, North Steyne and North Narrabeen beaches reopened on Wednesday morning, the day after they were closed after the discovery of the debris.
