Dubbed the world’s oldest-known cave art, the painting represented a 45,000-year-old life-size warty pig.
Dr Sven Ouzman, from University Western Australia’s School of Social Sciences, believes the latest discovery will help researchers better understand Australia’s Indigenous history.
He said: “This iconic kangaroo image is visually similar to rock paintings from islands in South East Asia dated to more than 40,000 years ago, suggesting a cultural link – and hinting at still older rock art in Australia.”
Cissy Gore-Birch, Chair of the Balanggarra Aboriginal Corporation, added: “It’s important that Indigenous knowledge and stories are not lost and continue to be shared for generations to come.
