Bradshaw paintings?
''Although local Aboriginal people were aware of the Gwion Gwion paintings adorning rock walls, the first European sighting and recording of these enigmatic figures was by grazier Joseph Bradshaw, hence the attribution of his ‘white fella’ name to these paintings. Bradshaw led an expedition in 1891 to survey potential grazing leases beyond the King Leopold Ranges in the Kimberley. One afternoon, in 1891, he and his brother separated from the main group and stumbled upon drawings that did not resemble the more familiar Wandjina-style paintings. He made sketches and later, upon returning to Melbourne, described the paintings in an address to the Royal Geological Society. His discovery excited interest, and a number of people went in search of the paintings. With the assistance of local Aboriginal people, many more sites were soon discovered. While Aboriginals in the Kimberley were painters responsible for maintenance of the Wandjina, they were less interested in the older Gwion Gwion paintings, claiming these were made by a different people long ago. Indeed, the only fixed date thus far for the antiquity of the Gwion Gwion is 17,500 years, obtained from dating a mud-wasp nest. It is likely that people painted the Gwion Gwion images on rock surfaces at the time of the last Glacial Maximum, 20,000 to 15,000 years ago''
Seems to be a lot of debate as to who painted them originally
