Collaboration between government and communities in disaster management has been demonstrated to create disaster risk reduction initiatives. However, implementing such collaboration poses challenges within regions characterised by dualism in governance. This study aims to investigate the disaster management system for coronavirus disease 2019 (COVID-19) in the context of dualism governance, where the state holds administrative control. Traditional authority (Adat) simultaneously regulates various facets of human life in Bali, Indonesia. The study used a qualitative approach, and data were gathered through in-depth interviews with 10 informants, 3 rounds of focus group discussions, and participant observations. The findings reveal that the dualism governance in Bali is manifested through responses to vulnerabilities within the community, Adat versus state laws, and the communication systems established between state administrative and traditional authorities during the COVID-19 response.Contribution: This study highlights the significant role of traditional governance in enhancing community resilience amid the limitations of state capacity in handling the COVID-19 pandemic. Despite conflicting interests with the state, traditional government plays a crucial role in fostering collective community action to address vulnerabilities. The study underscores the importance of greater involvement of Adat actors in disaster management within the context of dualism in governance, spanning from mitigation planning to preparedness, response and recovery. This involvement has the potential to bolster community resilience.
