This covers the glacial period before the post-glacial sea rise, 30,000 to 6,000 before the present. Aboriginals were making flake stone tools. Though for the most part natural forming cutting edges of quartz and chert were utilized Aboriginals evolved to adapt to hot conditions they survived the extremely cold conditions. Rottnest Island was inhabited during the fall in sea level but not thereafter.
