In the period from 18,000 to 15,000 years ago, Australia became dryer, with lower temperatures and less rainfall. Between 16,000 and 14,000 years ago the sea levels rose quickly. One scientist has estimated sea levels rose 50 feet in 300 years. At the end of the Pleistocene, about 13,000 years ago, rising sea levels cut the land access across the Torres Strait to New Guinea, the Bass Strait between Victoria and Tasmania, and to Kangaroo Island.
