Related neat thing: a 2018 article, based on a computer analysis of modern topographic data combined with seafloor surveys, which found that the first Australians island hopped through an extensive archipelago that is now utterly submerged, going from island to island, each destination easily visible from the hills or headlands of the previous one. In contrast to the view assumed in textbooks and articles I encountered over the years, that the first Australians basically sailed across 80 or so kilometers of open sea to a destination over the horizon and out of sight.
