Answer 1

Until about 12Kya, there was dry land almost all the way between Indonesia and Australia. Interestingly, Tasmania became isolated from mainland Australia at the end of the last Ice Age, and the people isolated there regressed technologically. There was even a small population that was isolated on Flinders Island, who, when discovered by Europeans, had even lost the use of fire and clothing.
