I will analyse the narratives about British nuclear testing in Australia (BNT) from Indigenous Australians, nuclear test veterans, and their supporters, who have worked to make BNT socially visible. The objectives are to reveal the harm and injustice inflicted, examine how narratives have made them visible, clarify the challenges of the visibility process, and explore ways to create effective policy and a better society in consultation with affected communities. The findings will have an impact beyond nuclear policies, encompassing other global challenges that require visibility such as climate crisis, toxic waste, chemical and biological weapons, and socio-political harms.
