The Torres Strait presents a unique case study in Australian archaeology where people settled an archipelago between two mainlands, creating a thriving maritime seafaring culture. Using 221 AMS radiocarbon dates, we examine initial occupation and settlement patterns in the first example of Bayesian chronological modelling applied to the Torres Strait as a whole, as opposed to the individual assessment of sites. This holistic approach uses data from 49 archaeological sites to develop a more holistic understanding of when people moved to, and between, islands throughout the archipelago. Existing human migration theories focus on movement of people between c.2500 and 4000 years ago; however, with a culture dating back at least 9000 years, this new chronological modelling enables us an opportunity to rethink how chronology informs our current understanding of key cultural adaptions relating to societal change and the onset of ritual activities.
