AbstractThis article examines the effective management and governance of World War II shipwrecks with a particular focus on two Australian wartime wrecks in Timor-Leste, HMAS Voyager and HMAS Armidale. With reference to international frameworks such as the 2001 UNESCO Convention on the Protection of the Underwater Cultural Heritage, as well as Timor-Leste’s evolving domestic regulations, this article explores the challenges in managing these shipwrecks and seeks to broaden the protection and preservation paradigm that defines approaches to other forms of underwater cultural heritage. Particular attention is given to balancing the interests of states, local communities and international actors, while addressing the legal, moral and environmental complexities and sensitivities associated with WWII wrecks. The article aims to contribute to the broader discourse on maritime heritage governance by providing insights into the complex and multiple challenges of managing WWII wrecks, within the context of a nation that only achieved lasting independence relatively recently.
