The First Peoples, Living Waters project is a knowledge and cultural exchange that responds to ongoing injustice caused by the denial of Indigenous water rights and jurisdiction over water in Australia. It brings Indigenous Peoples from three settler colonial states (Australia, Aotearoa New Zealand, and the US) into conversation to explore how treaty and agreement-making can lead to water law reform in settler colonial states. In the context of climate change, these conversations are especially urgent: as their waterways sicken under climate change, this directly affects Indigenous Peoples’ wellbeing. Increasing water scarcity is already being used as an excuse to prevent water returns to Indigenous Peoples. This chapter shares insights from the cultural and knowledge exchange, presented as a conversation between the authors.
