A tool classification of Pleistocene northern Australia and New Guinea and Southeast Asia comprised of hatchets, flakes, and other tools. Important sites include Nawamoyn, Malangangerr, Arnhem Land, Cape York, New Guinea Highlands. Edge-ground tools do not appear until the late Holocene elsewhere in Australia; they are completely absent from Tasmania. In Southeast Asia, it comprises flaked stone tools which are sharpened by grinding or polishing the cutting edge only. They existed in the Bacsonian and Hoabhinian periods.
