Maritime Coastal and Island Societies of Australia and New Guinea

Abstract

Abstract Coasts, islands, and marine resources played a central role in the dispersal of people into and across Sahul (the combined landmass of New Guinea and Australia). This vast area spans tropical and temperate latitudes, with changes in the abundance and distribution of coastal resources having greatly influenced how people used these landscapes. Little is known of early coastal and island occupation in the millennia after colonisation because sites of this antiquity are now under water, and most islands formed in the Holocene following the postglacial rise in sea level. Current evidence indicates that small, mobile populations harvested nearshore shellfish and fish by 44–42 ka, with long-distance sea voyaging and interisland trade apparent by 25–20 ka. Increasingly intensive coast and island use is evident by the Mid-Holocene, with specialised maritime economies emerging in tropical latitudes throughout the Late Holocene. Although large gaps remain in our understanding of coastally oriented lifeways, multidisciplinary studies are increasingly challenging global paradigms about the antiquity and importance of marine resources on human cultural development.
