As if that wasn’t enough for one Australian state, some years ago two stone axe heads were found in the Kimberley, which, through scientific dating, are now reckoned to be the oldest known man-made tools on the planet. Add to that the archaeological discovery in 2017 on Barrow Island, just off the Pilbara, of the earliest evidence of coastal living in Australia. But wait, it gets even better: on West Wallabi Island in the Abrolhos are the remains of Australia's oldest known European style structure, Wiebbe Hayes Stone Fort, dating from 1629. Now tell me we have nothing significantly old in Western Australia!
