The coal seam gas (CSG) industry has rapidly expanded in the Great Artesian Basin (GAB) over the past two decades, significantly impacting groundwater ecosystems and Indigenous communities that rely on these water sources for cultural, spiritual, and practical purposes. This article examines the intersection of Water Sovereignty, extractive industries, and key issues such as Social License to Operate (SLO), Indigenous Peoples' rights, informed consent, and the legal doctrine of Aqua Nullius. Through an Indigenous perspective, this research illuminates the multifaceted dimensions of water governance and the complexities that arise from the interactions between Indigenous stakeholders, industries, and regulatory frameworks. Through interviews with Elders of the Iman Peoples in central Queensland, the research highlights how current SLO frameworks neglect Free, Prior, and Informed Consent (FPIC) and fail to uphold ethical standards necessary for protecting Indigenous cultural continuity. Water security is a primary concern, with Traditional Owners emphasizing the need to safeguard surface and groundwater for future generations. This research informs policy at local and national levels while contributing to global discussions on Indigenous sovereignty, environmental justice, and cultural heritage protection. It calls for integrating Indigenous knowledge and rights into water governance, promoting respect, equity, and sustainability in managing natural resources.
