Sydney's Clovelly Beach remained closed yesterday as a red algal bloom lingers, making the waters resemble tomato soup. Blooms appeared at eastern suburb shorelines on Tuesday, forcing the closure of beaches at Bondi, Clovelly and Gordons Bay. Bondi Beach reopened but Randwick City Council said Clovelly remained closed as the bloom, caused by an upwelling of colder nutrient-rich water, lingered.
