Elevating and reinstating the cultural practices, knowledges, and contemporary priorities of coastal Indigenous groups are essential to the conservation of Sea Country in the face of changing climates and the emancipation of colonisation. To foster much-needed shifts in power and the governance structures associated with Sea Country management and research, Indigenous-led platforms for cross-cultural collaborations, research capacity strengthening, and strategic policy developments are vital. In South Australia, over the past three years, the South Australia First Nations-led Sea Country Research (FNSCR) Alliance, made up of Elders and/or representatives from five Aboriginal coastal groups across South Australia and supported by South Australian Government public servants and University researchers have successfully created a platform for facilitating Sea Country research, development and economic cross-cultural relationship building in an advisory capacity. This presentation provides insight into the establishment and successes and learnings of such a strategic Alliance. We will discuss our future aspirations under the banner of economic-social and cultural-ecological outputs whilst exploring the importance of understanding and embracing coastal cultural diversity and the time needed to strengthen and form meaningful relationships.
