New archaeological evidence has unveiled the Coral and Pearl Seaway, a prehistoric maritime network connecting Indigenous communities in Northern Australia with the Bismarck Archipelago. By analyzing the chemical signatures of Pinctada pearl shells and red coral beads, researchers have traced a 1,500-mile trade route that operated as early as 2,000 BCE.
This discovery challenges the traditional view of isolated maritime development in the region, suggesting that ancient seafaring technology was far more advanced than previously thought. The trade network facilitated not only the exchange of luxury items but also the diffusion of tool-making techniques and linguistic influences across the Coral Sea centuries before the arrival of Austronesian settlers.
