It was a quarter of a century ago that ANTIQUITY first announced the ‘Pleistocene colonization of Australia’, when Mulvaney (1964) reported secure dates before 12,000 b.p. from Kenniff Cave, Queensland. The last three years alone have seen dates from New Guinea of around 40,000 b.p., early dates from the offshore islands of the Bismarck Archipelago, and dates from Australia itself that show a rapid colonization of both the arid central desert and cold, wet Tasmania – environments very different from the tropical islands of Southeast Asia, whence the first Australasian populations must surely have come. It is a record with great implications for early settlement elsewhere, most plainly of the American continents.
