An Australian Aboriginal sacred site is a place deemed significant and meaningful by Aboriginal Australians based on their beliefs. It may include any feature in the landscape, and in coastal areas, these may lie underwater. The site's status is derived from an association with some aspect of social and cultural tradition, which is related to ancestral beings, collectively known as Dreamtime (or the Dreaming/s), who created both physical and social aspects of the world. The site may have its access restricted based on gender, clan or other Aboriginal grouping, or other factors.
