The notion that nasu tengara was never connected to mainland is not as certain as it seems to have been presented, nor is it as relevent as it is presented. The islands of nasu tengara form a violently active volcanic archipelago. The straits separating them from eachother and form other islands almost certainly hosted numerous now sunken volcanic islands and volcanic land bridges, similar to the thrice sunken and thrice risen krakatau. Even if not directly connected, the islands of nasu tengara almost certainly enjoyed stepping stone volcanic islands to other parts of indonesian islands such that progressive travel did not require anything more than perhaps axcidental vegetation mat over very short over water distances.
Also, as was revealed after krakatau eruption, large caldera forming eruptions near the sea in the Indonesian archipelago, such as in the straits between of Bali in question, form vast rafts of floating pumice stone hundreds of acres in size, that remain intact for month or years after the eruption. Many rafts from krakatau floated clean to Africa with wild life hitching rides, including some which appeareny carried bones of humans that lived for awhile on the rafts. So it also seem possible homo erectus could also have hitched rides on volcanic pumice rafts in the aftermath of large caldera forming eruptions in the various straits of Indonesia.
The accidental crossing of humans across the Atlantic is also not impossible. Old world monkeys definitely crossed the Atlantic, probably on storm driven vegetation mats, 40 million years ago, and went on to establish the entire population of new world monkeys. It does not seem impossible humans could have made Accidental crossing the same way.
