Secure archaeological evidence for human occupation on the eastern seaboard of Australia before ~ 25,000 years ago has proven elusive. This has prompted some researchers to argue that the coastal margins remained uninhabited prior to 25 ka. Here we show evidence for human occupation beginning between 30 ± 6 and 49 ± 8 ka at Wallen Wallen Creek (WWC), and at Middle Canalpin Creek (MCA20) between 38 ± 8 and 41 ± 8 ka. Both sites are located on the western side of Minjerribah (North Stradbroke Island), the second largest sand island in the world, isolated by rising sea levels in the early Holocene. The earliest occupation phase at both sites consists of charcoal and heavily retouched stone artefacts made from exotic raw materials. Heat-treatment of imported silcrete artefacts first appeared in sediment dated to ~ 30,000 years ago, making these amongst Australia’s oldest dated heat-treated artefacts. An early human presence on Minjerribah is further suggested by palaeoenvironmental records of anthropogenic burning beginning by 45,000 years ago. These new chronologies from sites on a remnant portion of the continental margin confirm early human occupation along Sahul’s now-drowned eastern continental shelf. [ABSTRACT FROM AUTHOR]

Stable isotope analysis of bone apatite oxygen (δ18O) and carbon (δ13C) was undertaken for modern and archaeological spectacled hare wallaby (Lagorchestes conspicillatus) bone collected from an 1880s indentured labor confinement camp on Barrow Island in Western Australia. δ18O results and historical climate data indicate decreased annual precipitation during occupation of the site and provide insight into the conditions experienced by Aboriginal pearling laborers incarcerated on the offshore island. δ13C values may reflect variation in water availability or a short-term vegetation change resulting from landscape burning. This study is the first application of macropod bone apatite isotopic analysis in an Australian historical context and demonstrates its significant potential for identifying recent environmental changes to a high level of sensitivity.

Specimen identification is the backbone of archeozoological research. The challenge of differentiating postcranial skeletal elements of closely related wild animals in biodiverse regions can prove a barrier to understanding past human foraging behaviours. Morphometrics are increasingly being employed to classify paleozoological animal remains, however, the potential of these methods to discriminate between wild animal groups has yet to be fully realised. Here we demonstrate the applicability of a traditional morphometric approach to taxonomically classify foot and ankle bones of kangaroos, a large and highly diverse marsupial family. Using multiple discriminant analysis, we classify archaeological specimens from Boodie Cave, in northwest Australia and identify the presence of two locally extinct macropod species during the terminal Pleistocene. The appearance of the banded hare-wallaby and northern nail-tail wallaby in the Pilbara region at this time provides independent evidence of the ecological and human responses to a changing climate at the end of the last Ice Age. Traditional morphometrics provides an accessible, inexpensive, and non-destructive tool for paleozoological specimen classification and has substantial potential for applications to other diverse wild faunas.

Use of Indigenous divers on nineteenth-century northwest Australian pearling luggers gave rise to a transregional apparatus of coercion, physical mistreatment, and arguably, slavery. Where accounts of conditions experienced by divers are limited to the documents of contemporary colonial men, our contribution explores a rare archaeological perspective. Zooarchaeological and taphonomic analysis of the Bandicoot Bay campsite, Barrow Island, evokes an exploitative labor relationship inherited from a wider colonial process yet actively renegotiated by its participants through subsistence practices. The operation's pearlers selected a camp that advantaged concerns for labor organization and resource management while their divers seized opportunities for self-directed subsistence.

The time of arrival of people in Australia is an unresolved question. It is relevant to debates about when modern humans first dispersed out of Africa and when their descendants incorporated genetic material from Neanderthals, Denisovans and possibly other hominins. Humans have also been implicated in the extinction of Australia's megafauna. Here we report the results of new excavations conducted at Madjedbebe, a rock shelter in northern Australia. Artefacts in primary depositional context are concentrated in three dense bands, with the stratigraphic integrity of the deposit demonstrated by artefact refits and by optical dating and other analyses of the sediments. Human occupation began around 65,000 years ago, with a distinctive stone tool assemblage including grinding stones, ground ochres, reflective additives and ground-edge hatchet heads. This evidence sets a new minimum age for the arrival of humans in Australia, the dispersal of modern humans out of Africa, and the subsequent interactions of modern humans with Neanderthals and Denisovans.
