Abstract We report evidence for the world’s earliest ground-edge axe, 44–49,000 years old. Its antiquity coincides with or immediately follows the arrival of humans on the Australian landmass. Ground/polished axes are not associated with the eastward dispersal of Homo sapiens across Eurasia and the discovery of axes in Australia at the point of colonisation exemplifies a diversification of technological practices that occurred as modern humans dispersed from Africa. Ground-edge axes are now… 
Human occupation of northern Australia by 65,000 years ago
TLDR
The results of new excavations conducted at Madjedbebe, a rock shelter in northern Australia, set a new minimum age of around 65,000 years ago for the arrival of humans in Australia, the dispersal of modern humans out of Africa, and the subsequent interactions ofmodern humans with Neanderthals and Denisovans.
Non-destructive Provenancing of Ground-Edged Mafic Artifacts: A Holocene Case Study from the Sydney Basin, Australia
ABSTRACT Ground-edged artifacts were an important part of the Australian Aboriginal toolkit. They had practical day-to-day uses, but some had symbolic and social values that led to their movement
Early ground axe technology in Wallacea: The first excavations on Obi Island
TLDR
The emergence of ground axes on Obi is an independent example of a broader pattern of intensification at the Pleistocene-Holocene transition in Wallacea and New Guinea, evincing human innovation in response to rapid environmental change.
Palaeolithic seafaring in East Asia: testing the bamboo raft hypothesis
Abstract The earliest colonisation of oceanic islands by Homo sapiens occurred ~50 000–30 000 years ago in the Western Pacific, yet how this was achieved remains a matter of debate. With a focus on

TLDR
The archaeological and genetic evidence points to a single successful dispersal event, which took genetically and culturally modern populations fairly rapidly across southern and southeastern Asia into Australasia, and with only a secondary and later dispersal into Europe.
