Central Coast Council has now confirmed building waste turning up at Wamberal Beach does contain asbestos.
Up until now, it's only been referred to as 'suspected asbestos'.
In a statement yesterday afternoon (below), the local government revealed experts believe it's a low-risk material.
While it'll continue daily inspections to clean up any offending objects.
Council continues to work to figure out just what the source is.
Both Terrigal and Wamberal Beaches remain open to the public.
