 Scientifically, the excavation of the canal provided a valuable contribution to the understanding of the changing sea-levels along the eastern seaboard and the antiquity of the aboriginal presence in the area.Intact original sections of the fascine dyke sandstone construction are rare examples of late 19th century coastal engineering works.The area has been assessed as having no potential to contain historical archaeological material associated with the development or occupation of the area, either prior to or since the construction of the canal.
