Abstract

Without a doubt, boomerangs are one of the Sunshine State’s symbols. But forget everything you know about their ‘returning effect’. Whereas returning boomerangs were only used for games and learning purposes, non-returning boomerangs were complex, multifunctional tools. They played a crucial role in Indigenous communities’ daily lives in Queensland and other parts of Australia. In our work, we put together Traditional knowledge and experimental archaeology to investigate a forgotten use of boomerangs: modifying the edges of stone tools. This activity is fundamental to producing a variety of stone implements, each of them with a specific function. In our study, experimental replicas of boomerangs proved very functional to shape stone tools. Our results are the first scientific proof of the multipurpose nature of these iconic objects.
