Boodie Cave is a coastal limestone shelter on the Ningaloo Coast of Western Australia noted for Late Pleistocene and Holocene archaeological deposits. The site has produced extensive assemblages that inform debates in Australian prehistory, Quaternary science, and paleontology. Its stratified sequence links to regional processes recorded in climatic reconstructions and Indigenous occupation narratives.

Location and geology

Boodie Cave is situated on the Cape Range peninsula within Cape Range National Park near the Ningaloo Reef and adjacent to the Exmouth Gulf and Indian Ocean. The shelter is formed in Pleistocene aeolianite and marine limestone correlated with regional stratigraphy such as the Guilderton Formation and Tamala Limestone. The cave's geomorphology relates to sea-level fluctuations recorded in studies of the Last Glacial Maximum, the Holocene transgression, and coastal uplift events associated with the Australian continental margin. Karst processes and solutional weathering produced overhangs and stratified deposits linked to sediment sources from the Cape Range karst system and fluvial inputs from ephemeral channels draining to the Indian Ocean. The site lies within lands traditionally associated with the Yindjibarndi and regional Indigenous groups whose oral geographies intersect with mapped features like the Ningaloo Coast World Heritage Area.

Archaeological significance

Boodie Cave is prominent in discussions of human colonization of Sahul, contributing data to comparisons with sites such as Lake Mungo, Kow Swamp, Mungo Lady contexts, and continental sequences from Kangaroo Island and Tasmania's Kutikina Cave. Radiocarbon and optically stimulated luminescence dating at the site have been integrated into regional chronologies alongside records from Devil's Lair, Willandra Lakes Region, and the Great Australian Bight. The assemblage provides evidence relevant to models proposed by researchers at institutions including the Australian National University, the University of Western Australia, and the Western Australian Museum. Boodie Cave informs debates about coastal refugia hypotheses, demographic change during the Younger Dryas, and the impacts of Holocene sea-level rise on mobile hunter-gatherer populations documented across the Indian Ocean rim and the broader Indo-Pacific.

Human occupation and artifacts

Excavations at Boodie Cave have recovered stratified lithic assemblages, butchered fauna, and hearth features comparable to artifacts from Caves of the Cape Range and coastal sites like Mandu Mandu Creek localities. Stone tool types include edge-retouched flakes, backed artifacts, and expedient cores that complement typologies developed for the Pleistocene archaeology of Australia. Organic remains recovered under anaerobic conditions include charred plant residues and worked bone comparable to finds reported from Puritjarra and Cuddie Springs. Evidence for repeated episodic use, hearth construction, and resource processing at Boodie Cave has been interpreted in light of ethnographic analogues involving coastal foragers documented by researchers collaborating with Aboriginal communities and heritage bodies such as the Australian Institute of Aboriginal and Torres Strait Islander Studies and the Department of Biodiversity, Conservation and Attractions (Western Australia).

Faunal remains and paleoenvironment

The faunal assemblage from Boodie Cave includes small to medium-sized marsupials, macropods, seabirds, and marine shell middens that contribute to reconstructions of past ecosystems alongside records from Shark Bay and Montebello Islands. Taphonomic analyses reveal human modification on bones and the presence of extinct or locally extirpated taxa, which informs regional extinction narratives similar to discussions around megafauna extinctions in Sahul and sites like Cuddie Springs. Stable isotope studies and palaeobotanical evidence from sediments link assemblages at Boodie Cave to palaeoclimatic proxies such as speleothem records, marine microfauna, and pollen sequences used in Holocene environmental reconstructions by teams associated with the Commonwealth Scientific and Industrial Research Organisation and several university palaeoecology groups.

Conservation and management

Boodie Cave is managed under the statutory frameworks governing Cape Range National Park and the Ningaloo Coast World Heritage listing, involving coordination between the Western Australian Museum, state agencies, and Traditional Owners. Access is regulated to protect stratified deposits, and salvage, monitoring, and curation protocols follow standards developed by the Australian Heritage Commission and Australian cultural heritage legislation administered by the Department of the Environment (Australia). Conservation measures address threats from coastal erosion, visitor impacts, and illegal collection, with mitigation strategies drawing on best practices from international sites such as Lascaux (for rock-shelter protection) and coastal archaeological programs in the Pacific Islands.

Research history and excavations

Systematic investigations at Boodie Cave began through multidisciplinary projects involving archaeologists, palaeontologists, geochronologists, and Indigenous stakeholders. Fieldwork teams have published results in collaboration with institutions including the Western Australian Museum, the University of Wollongong, and the Australian National University. Key methodological contributions include application of radiocarbon dating, optically stimulated luminescence, micromorphology, zooarchaeology, and ancient DNA protocols aligned with international standards promoted by bodies like the International Council on Monuments and Sites and the Society for American Archaeology. Ongoing research programs emphasize community co-management, data sharing with Aboriginal ranger groups, and integration of Boodie Cave data into continental syntheses alongside datasets from Lake Eyre Basin, the Nullarbor Plain, and other Pleistocene-Holocene repositories.
