Lady Robinsons Beach is the stretch of beach between the mouth of the Cooks River and the mouth of Georges River on the western shore of Botany Bay. Originally the beach was known as Seven Mile Beach. The beach was renamed after the wife of the then Governor, Sir Hercules Robinson. Isolated settlements separated from the beach by sand dunes were also given the name of Lady Robinson's Beach as their postal address. Lady Robinsons Beach is the eastern boundary of the area known as the St George District.
