Australasia (49,293 – 28,578 BCE): Upper Pleistocene I — Continental Shelves, Fire Country, and the Unpeopled Islands of the Far South

Geographic & Environmental Context

During the long glacial prime of the Late Pleistocene, Australasia stretched as a single vast, connected super-land: the Sahul continent, where Australia, New Guinea, and Tasmania were joined by the broad Arafura and Carpentaria shelves, while across the Tasman Sea, the New Zealand–Norfolk–Kermadec arc stood isolated, volcanically active, and entirely uninhabited by humans.

The region’s physiography displayed extremes of exposure and contrast:

• To the north, tropical savannas and monsoon coasts extended from Kimberley and Arnhem Land through Cape York to the low divide of southern New Guinea, while the Gulf of Carpentaria held a vast inland sea–wetland complex.

• Across central and southern Australia, vast dune fields, salt lakes, and desert basins alternated with fertile riverine corridors like the Murray–Darling and the Willandra Lakes.

• In the south, the Bassian Plain connected the mainland to Tasmania, while New Zealand remained beyond human reach—its forests, volcanic zones, and seabird cliffs untouched.

Sea level lay ~100 m below present, enlarging the continental shelves and exposing wide coastal plains, which were colonized by both humans (in Australia) and dense faunal populations.

Climate & Environmental Shifts

• Early Glacial Phase (~49–35 ka): Gradual cooling, declining precipitation in continental interiors, and expansion of arid belts; forest contraction in the tropics and southeast.

• Approach to the Last Glacial Maximum (~35–28 ka): Sharper temperature drop, stronger seasonality, and intensified westerlies and trade winds. Northern monsoons weakened, and interior lakes fell or dried episodically.

• Regional Contrasts:
  • Northern Australia remained humid enough for monsoon-driven wet–dry cycles, sustaining aquatic ecosystems along rivers and coasts.
  • Southern Australia and Tasmania cooled markedly, with snowfall on upland ranges and alpine conditions in the Great Dividing Range and Tasmanian highlands.
  • New Zealand entered full glaciation: the Southern Alps carried expanded glaciers, and snowlines dropped by hundreds of meters.

The climate oscillated between long cold stasis and short, mild interstadials—conditions that defined both human adaptive strategies and the evolutionary dynamics of uninhabited island ecologies.

Human Presence and Lifeways

Human societies were firmly established across the Australian continent and the connected Sahul landmass, but absent east of the Tasman frontier.

Northern Australasia (Sahul Tropics)

• Occupation and Range:
  Continuous habitation in Arnhem Land, the Kimberley, Cape York, and the Gulf lowlands; movement extended across the Arafura Plain into southern New Guinea.

• Economy:
  Broad-spectrum foraging—fish, shellfish, turtles, dugong, and small terrestrial game. During glacial lowstands, coastal groups ranged across the now-submerged shelf flats, exploiting estuaries and reefs.

• Technology:
  Sophisticated flake–blade industries, hafted points, resin adhesives, and early ground ochre use; fiber and wooden implements (spears, nets, traps) widely employed.

• Symbolism:
  Earliest rock art phases—engraving and pigment painting—appeared in the Kimberley and Arnhem Land, along with structured burials and cremations.

• Resilience:
  Estate-based mobility tracked monsoon pulses; access to the flooded Carpentaria lowland and inland freshwater refugia buffered against droughts.

Southern Australasia (Southern Australia, Tasmania, South Island New Zealand)

• Australia:
  Long-settled communities adapted to harsh continental variability. Along the Willandra Lakes and Murray–Darling Basin, people fished, hunted marsupials, collected seeds and tubers, and practiced ceremonial cremation and burial rites (Mungo).
  On the expanded southern shelf coasts, foragers harvested shellfish, seals, pinnipeds, and stranded whales, while inland hunters pursued kangaroos, emus, and small marsupials.
  The use of fire to manage vegetation—so-called fire-stick farming—maintained open grasslands and supported reliable game.

• Tasmania (then mainland-connected):
  Populations ranged across the Bassian Plain, exploiting riverine corridors and coastal flats for waterfowl and fish; early cold-adapted hearth traditions emerged.

• New Zealand and sub-Antarctic arcs:
  Entirely uninhabited, though South Island glaciers carved fjords and plains later to support Holocene ecosystems.

Unpeopled Frontiers: South Polynesia and Oceanic Arcs

East of Sahul, the South Polynesian sector (New Zealand, Norfolk, Kermadec, Chatham Islands) remained a wilderness of volcanic highlands, periglacial coasts, and seabird colonies.
The Oruanui eruption (c. 25.5 ka BP) from the Taupō caldera in New Zealand blanketed the North Island and offshore ridges with tephra, reshaping soils, lakes, and drainage systems.
Forests shifted between podocarp–broadleaf canopies and scrub–grassland mosaics; moa and Haast’s eagle dominated terrestrial food webs, while offshore seabird realms thrived on predator-free islets.

Technology & Material Culture

Across Sahul, technology mirrored a mature foraging economy:

• Stone: flake–blade cores, backed microliths, and grindstones; heat treatment and resin hafting.

• Organic: spears, clubs, nets, and wooden shields; fiber technology for carrying and trapping.

• Pigment and ornament: widespread ochre use for painting, body decoration, and burial; shell and tooth ornaments signal social identity.

• Fire technology: mastery of landscape burning as a central environmental tool.

Movement & Interaction Corridors

• Land and River Networks: the Murray–Darling, Willandra, and Lake Eyre basins functioned as arteries linking interior and coast.

• Shelf and Coast Routes: mobile bands traversed the exposed Sahul shelves, harvesting estuarine resources and migrating seasonally.

• Northern Gateways: travel between northern Australia and southern New Guinea maintained genetic and cultural interchange across the connected shelf.

• Southern Pathways: the Bassian Plain allowed movement between mainland and Tasmania until postglacial flooding severed the link.

Cultural & Symbolic Expressions

• Ritual landscapes: rock shelters and burial grounds (e.g., Willandra) reveal early ceremonial organization.

• Artistic innovation: hand stencils, engraved motifs, and ochre figurative painting predate 30 ka in northern Australia.

• Fire and mythic space: controlled burning likely embedded in cosmological understanding of land stewardship.

Environmental Adaptation & Resilience

Australasia’s Pleistocene societies mastered the ecology of variability:

• Mobility with continuity: shifting among waterholes, estuaries, and resource belts on seasonal rhythms.

• Storage through knowledge: environmental mapping replaced physical storage—knowing when and where resources renewed was key.

• Fire as technology: selective burning maintained mosaics that sustained wildlife and plant yields.

• Refugia strategies: wetlands and monsoon belts offered fallback zones through glacial droughts.

The unpeopled islands to the east, by contrast, evolved ecological self-sufficiency—volcanic fertility, avian abundance, and intact forests awaiting future colonists.

Transition Toward the Next Epoch

By 28,578 BCE, the Australasian world stood poised at the threshold of deglaciation:

• Sea-level minima connected lands and compressed ecologies into wide continental shelves.

• Human societies in Sahul had adapted to every climate zone, from arid interior to reef coast, with rich symbolic traditions already in place.

• Islands beyond the Sahul frontier—New Zealand, Norfolk, Chatham, Kermadec—remained avian kingdoms without humans.

As ice sheets began their slow retreat, the landscapes and coastlines that would shape the Holocene—estuaries, islands, and archipelagos—were already being prepared by the patient interplay of fire, flood, and time.

Northern Australia — 49,293–28,578 BCE

Southern Australasia (28557 – 7822 BCE): Southern Lands of Long Continuity

Geographic and Environmental Context

Southern Australasia—including southern Australia (New South Wales, Victoria, South Australia, southern Western Australia, Tasmania) and the temperate regions of New Zealand’s North and South Islands—was defined by varied landscapes: eucalyptus forests, open grasslands, alpine highlands, and extensive river systems such as the Murray–Darling Basin.

• Tasmania was joined to mainland Australia by a dry Bassian Plain during much of this period due to lower sea levels.

• New Zealand remained uninhabited by humans, but its forests, wetlands, and alpine zones supported rich endemic fauna.

Climate and Environmental Shifts

• Last Glacial Maximum (c. 26,500 – 19,000 BCE): Cooler and drier; Tasmania and southern mainland Australia experienced expanded grasslands and reduced forest cover. Glacial and periglacial conditions occurred in alpine regions of Tasmania and New Zealand. Lower sea levels exposed broad coastal plains, altering resource distribution.

• Bølling–Allerød (c. 14,700 – 12,900 BCE): Warmer, wetter conditions favored forest regeneration, increased river flows, and more stable seasonal resources. Coastal productivity rose as sea levels began to climb.

• Younger Dryas (c. 12,900 – 11,700 BCE): A return to cooler, drier conditions contracted forests again and reduced water availability in some inland basins.

• Early Holocene (after c. 11,700 BCE): Warmer and more stable climates brought renewed forest expansion in Australia’s south, rising seas flooded the Bassian Plain, isolating Tasmania, and reshaped coastlines.

Subsistence and Settlement

• Aboriginal Australians in southern Australia and Tasmania practiced highly mobile seasonal foraging, exploiting coastal fisheries, estuarine shellfish beds, kangaroos, wallabies, emus, and a wide array of plant foods—roots, tubers, seeds, and fruits.

• Coastal and riverine camps were favored in warmer months; uplands and inland plains were used for hunting in cooler periods.

• In Tasmania, marine resources such as seals and shellfish were crucial in winter when plant foods were scarce.

• New Zealand, still without humans, supported moa, giant eagles, waterfowl, and dense forests unaffected by human hunting or fire.

Technology and Material Culture

• Stone toolkits featured ground-edge axes, scrapers, and microliths hafted into composite implements.

• Wooden spears, clubs, and digging sticks were crafted and maintained with stone tools; bark and plant fibers were used for nets and baskets.

• Coastal groups used canoes or rafts for nearshore travel and fishing.

• Ochre was widely used for body decoration, ceremonial purposes, and possibly hide preparation.

Movement and Interaction Corridors

• Seasonal mobility linked inland hunting grounds with coastal and riverine resource zones.

• In the LGM, expanded coastal plains provided rich but temporary habitats that were later submerged in the Holocene.

• Rivers such as the Murray–Darling provided both resource corridors and travel routes across otherwise dry inland areas.

Cultural and Symbolic Expressions

• Rock art in southern Australia and Tasmania depicted animals, human figures, and symbolic designs, often tied to Dreaming narratives and ecological knowledge.

• Ceremonial gatherings coincided with seasonal abundance—such as fish migrations or plant harvests—reinforcing social ties and shared territorial understandings.

Environmental Adaptation and Resilience

• Fire-stick farming maintained open hunting grounds, promoted edible plant species, and reduced wildfire risks.

• Knowledge of seasonal cycles, animal migrations, and plant fruiting patterns was central to survival.

• Mobility and diversified diets ensured resilience during climate swings, especially in drier Younger Dryas years.

Transition Toward the Holocene

By 7822 BCE, rising seas had isolated Tasmania, New Zealand remained untouched by humans, and southern Australia’s foragers had fully adapted to postglacial landscapes. The enduring ecological knowledge systems in southern Australia would maintain cultural continuity for millennia.

Northern Australia (28557 – 7822 BCE): Monsoon Coasts and Inland Savannas

Geographic and Environmental Context

Northern Australia—including northern Queensland, the Northern Territory’s Top End, and the Kimberley region of Western Australia—was defined by a monsoonal climate with distinct wet and dry seasons.

• Coastal zones included mangrove-fringed estuaries, tidal flats, and offshore reefs.

• Inland savannas were dotted with billabongs and seasonal streams, backed by sandstone escarpments and open woodland.

• During lower sea levels, the Arafura Plain connected Australia to New Guinea, creating a vast Sahul landmasswith extensive northern coastal plains.

Climate and Environmental Shifts

• Last Glacial Maximum (c. 26,500 – 19,000 BCE): Cooler, drier conditions weakened the summer monsoon; many wetlands shrank, and coastal plains expanded seaward. Mangroves retreated, and inland waterholes became critical dry-season refuges.

• Bølling–Allerød (c. 14,700 – 12,900 BCE): Warming and stronger monsoon rains revitalized floodplains and coastal ecosystems; mangroves expanded, and inland plant productivity increased.

• Younger Dryas (c. 12,900 – 11,700 BCE): Slightly cooler and drier conditions contracted wetlands and reduced some seasonal streams; resource reliability declined in more arid inland pockets.

• Early Holocene (after c. 11,700 BCE): Full monsoon strength returned; rising seas inundated low-lying plains, creating the modern Gulf of Carpentaria and Torres Strait, and reshaping northern coastlines.

Subsistence and Settlement

• Coastal foragers harvested fish, shellfish, dugong, marine turtles, and seabirds, using tidal rhythms to maximize catches.

• Inland groups hunted wallabies, kangaroos, and emus; trapped waterfowl during wet-season breeding; and gathered yams, pandanus fruit, and nuts.

• Seasonal movement followed the monsoon cycle: wet-season inland dispersal to exploit aquatic and plant abundance, dry-season concentration along reliable waterholes and the coast.

• During the LGM and Younger Dryas, increased reliance on freshwater and estuarine fishing helped buffer against terrestrial resource scarcity.

Technology and Material Culture

• Stone toolkits included flaked and ground-edge axes, scrapers, and backed microliths.

• Wooden spears, throwing sticks, and clubs were adapted for both terrestrial hunting and fishing.

• Bark canoes and rafts allowed nearshore fishing and travel along rivers and estuaries.

• Ochre was widely used in rock art and ceremonial contexts.

Movement and Interaction Corridors

• The exposed Arafura Plain during low sea level created overland routes between Arnhem Land and southern New Guinea, enabling cultural and genetic exchange.

• River corridors such as the Victoria and Daly in the Top End, and the Fitzroy in the Kimberley, linked inland and coastal groups.

• Stone raw material and ochre sources were important nodes in seasonal mobility patterns.

Cultural and Symbolic Expressions

• Rock art traditions flourished, with depictions of animals, human figures, and geometric designs—some possibly representing ancestral beings in Dreaming narratives.

• Ceremonial gatherings at key wet-season sites reinforced alliances and facilitated exchange.

Environmental Adaptation and Resilience

• Seasonal mobility and ecological mapping of plant and animal cycles ensured reliable access to food.

• Fire management maintained hunting grounds and encouraged the growth of edible plants.

• Dietary diversity and resource-sharing between groups buffered against unpredictable rainfall.

Transition Toward the Holocene

By 7822 BCE, Northern Australia’s coastlines were reshaped by rising seas, the Arafura Plain was flooding, and rich monsoonal ecosystems supported dense seasonal gatherings. The integration of marine and terrestrial resources in subsistence strategies ensured continuity of lifeways through these environmental transformations.

…Australia by 6000 BCE, isolating the Aboriginal Tasmanians who live there from the mainland, and formed the Torres Strait, separating Australia from New Guinea.

Southern Australasia (2637 – 910 BCE): Southern Lands of Long Continuity

Geographic and Environmental Context

Southern Australasia—including southern Australia (New South Wales, Victoria, South Australia, southern Western Australia, and Tasmania) and the temperate regions of New Zealand’s North and South Islands—was marked by diverse landscapes: eucalyptus forests, grasslands, coastal estuaries, alpine highlands, and extensive river systems such as the Murray–Darling Basin. Tasmania’s cooler, wetter climate supported temperate rainforests in the west, while New Zealand’s high mountains and fertile lowlands remained uninhabited in this period.

Subsistence and Settlement

By the mid–third millennium BCE:

• Aboriginal Australians in the south practiced seasonal mobility, moving between coastal, riverine, and inland zones according to food availability.

These lands formed both a cultural heart of resilience and an ecological frontier soon to enter human history.
