.
To the north and east of New Guinea, the islands of Near Oceania (the
Bismarck Archipelago and the Solomons) were likewise never connected to Sahul by dry land, for deep-water trenches also separate these from the Australian
continental shelf.
It seems that human colonization of this region was most likely effected during the interval between 60,000 and 40,000 years ago, although some researchers would push the possible dates earlier. But the key point is that even when the oceans were at their lowest levels, there were always significant open-water gaps between the islands of Wallacea, and therefore, the arrival of humans into Sahul, necessitated over-water transport.
This was also the case of the expansion of humans beyond New Guinea into the archipelagoes of Near Oceania. Herein lies one of the most exciting and intriguing aspects of Pacific prehistory: that we are likely dealing with the earliest purposive voyaging in human history.
