This presentation will briefly trace 70,000 years of cultural evolution from the ancient crossing from Sunda to Sahul, via the swift continental colonization during the Ice Age, through the severe impacts on survival during the Last Glacial Maximum, and the socio-territorial reconfigurations during Holocene sea-level rise. The Australian Aboriginal world had become characterized by low environmental impact habitation, complex social organization systems anchored within constructed sacred origin histories, the persistence of relatively simple dwelling types situated within complex settlement sociospatial structures, and a high quality of life for most, with institutional dispute resolution mechanisms to contain conflicts.
