According to  Professor O'Connor, this predates all other known evidence of axe , as in where evidence of hafted axes around 35,000 years old has been found. Professor O'Connor said, "Nowhere else in the world do you get axes at this date [...] in most countries in the world they arrived with agriculture after 10,000 years ago." Analysis by  Professor Peter Hiscock of the showed the axe-head was made of , a hard volcanic rock. Axe-heads like this one would have been ground against a softer rock to shape and polish them. This recent discovery indicates the early inhabitants of Australia developed and used complex tools soon after they arrived in Australia 50,000 to 55,000 years ago.
