This study presents the first data on a level one archaeology student cohort, exploring their demographic composition and motivations for enrolling, as well as external stressors such as health and caring responsibilities that may influence student study goals, retention, and needs. A survey of 107 students enrolled in introductory level archaeology units at 13 Australian universities was undertaken in Semester 1, 2021. The results show a diverse cohort by age, gender, and educational background. Consistent with the professional Australian archaeological community, there is little diversity in the ethnicity of enrolled students. Further, many respondents reported having caring responsibilities, and both physical and mental health concerns. Students were motivated to enrol both for general interest and future career pathways; however, there was a poor understanding within the cohort of Australian archaeological job opportunities. These results indicate that there is clearly much to be done in public archaeological engagement and outreach in Australia. What is required of the Australian archaeological community is a concerted effort to improve how the discipline is taught and learned across all levels of education, and a collaborative approach to designing teaching methods suitable for our modern student cohort.

We review current zooarchaeological practice in Australia, identifying major research themes and key methodological gaps where opportunities exist for the development of Australian zooarchaeology as a discipline. We demonstrate that marsupial remains form a significant component of Australian zooarchaeological assemblages, yet high resolution taxonomic identification of these remains continues to prove challenging, owing to a combination of high species diversity and few resources which provide diagnostic criteria for discriminating morphologically similar, but ecologically variable taxa. The lack of robust protocols for discriminating marsupial taxa significantly impacts our ability to effectively integrate zooarchaeological data into broader narratives of Aboriginal colonisation, resilience and adaptation across Australia. Publication of identification protocols would help refine and standardise diagnostic criteria used between analysts, improve the methodological transparency of zooarchaeological analysis and provide resources for the training of a new generation of specialists. A range of opportunities currently exist, utilising qualitative and quantitative techniques, to significantly contribute towards the methodological robustness of zooarchaeological practice in Australia.

This contribution synthesizes archaeological studies of human economies from the Barrow–Montebello islands and uses the area's archaeological record to determine the effects of Late Pleistocene and early Holocene sea-level rise on regional coastlines. At the height of the Last Glacial Maximum (LGM), Australia's north-western coast extended much further west than the present-day shoreline. During subsequent sea-level rise, the gently prograding continental shelf was inundated, and with it, nearly all archaeological evidence for coastal occupation. The Barrow and Montebello Islands are one of the few exceptions, as they corresponded to inland hinterland ranges during the LGM, with the coastline lying some 50 km to their west. Evidence from all late Pleistocene and Holocene occupation phases of the Barrow–Montebello Islands demonstrate that foragers continued to visit the coast and engage in the exploitation of both terrestrial and marine environments. During the late Pleistocene, when the shoreline was 10–15 km away, coastal exploitation is seen through the presence of transportable estuarine and rocky-shore gastropods. By the early Holocene, when sea-levels were within close proximity of the sites, there is a marked increase in marine fauna including reef fish, estuarine and reef shellfish, crustaceans and estuarine crocodile. Together, this suggests that the nearby muddy, procumbent coastlines were productive, as well as an important component of coastal and hinterland economies. [ABSTRACT FROM AUTHOR]

This paper presents the first application of mammal tooth enamel carbonate stable isotope analysis for the purpose of investigating late Pleistocene–early Holocene environmental change in an Australian archaeological context. Stable carbon (δ13C) and oxygen (δ18O) isotope ratios were analyzed from archaeological and modern spectacled hare wallaby (Lagorchestes conspicillatus) and hill kangaroo (Osphranter robustus) tooth enamel carbonates from Boodie Cave on Barrow Island in Western Australia. δ18O results track the dynamic paleoecological history at Boodie Cave including a clear shift towards increasing aridity preceding the onset of the Last Glacial Maximum and a period of increased humidity in the early to mid-Holocene. Enamel δ13C reflects divergent species feeding ecology and may imply a long-term shift toward increasing diversity in vegetation structure. This study contributes new data to the carbonate-isotope record for Australian fauna and demonstrates the significant potential of stable isotope based ecological investigations for tracking paleoenvironment change to inter-strata resolution.

There are few archaeological sites that contain records for Pleistocene coastal occupation in Australia, as is the case globally. Two major viewpoints seek to explain why so few sites exist. The first is that the Pleistocene coast was a relatively marginal environment where fluctuating sea levels actively inhibited coastal resource productivity until the mid-to-late Holocene. The second position suggests that the Pleistocene coast (and its resources) was variably productive, potentially hosting extensive populations, but that the archaeological evidence for this occupation has been submerged by sea level rise. To help reconcile these perspectives in Australia, this paper provides a review, discussion, and assessment of the evidence for Australian Pleistocene coastal productivity and occupation. In doing so, we find no reason to categorically assume that coastal landscapes were ever unproductive or unoccupied. We demonstrate that the majority of Pleistocene coastal archaeology will be drowned where dense marine faunal assemblages should only be expected close to palaeo-shorelines. Mixed terrestrial and marine assemblages are likely to occur at sites located >2 km from Pleistocene shorelines. Ultimately, the discussions and arguments put forward in this paper provide a basic framework, and a different set of environmental expectations, within which to assess the results of independent coastal research. • Addresses Pleistocene coastal occupation and productivity in Australia. • Australian Pleistocene coasts were likely widely occupied and variably productive. • A basic framework within which to assess coastal occupation patterns is provided.

Published ages of >50 ka for occupation at Madjedbebe (Malakunanja II) in Australia's north have kept the site prominent in discussions about the colonisation of Sahul. The site also contains one of the largest stone artefact assemblages in Sahul for this early period. However, the stone artefacts and other important archaeological components of the site have never been described in detail, leading to persistent doubts about its stratigraphic integrity. We report on our analysis of the stone artefacts and faunal and other materials recovered during the 1989 excavations, as well as the stratigraphy and depositional history recorded by the original excavators. We demonstrate that the technology and raw materials of the early assemblage are distinctive from those in the overlying layers. Silcrete and quartzite artefacts are common in the early assemblage, which also includes edge-ground axe fragments and ground haematite. The lower flaked stone assemblage is distinctive, comprising a mix of long convergent flakes, some radial flakes with faceted platforms, and many small thin silcrete flakes that we interpret as thinning flakes. Residue and use-wear analysis indicate occasional grinding of haematite and woodworking, as well as frequent abrading of platform edges on thinning flakes. We conclude that previous claims of extensive displacement of artefacts and post-depositional disturbance may have been overstated. The stone artefacts and stratigraphic details support previous claims for human occupation 50–60 ka and show that human occupation during this time differed from later periods. We discuss the implications of these new data for understanding the first human colonisation of Sahul. [ABSTRACT FROM AUTHOR]
