The dual threats of climate change and anthropogenic impacts pose increasing challenges for Australia’s Sea Country. The Indigenous Knowledges of Northern Australia’s coastlines and the Great Barrier Reef are not well integrated into managing Sea Country. Indigenous Knowledges are unique local knowledges of place, connecting nature, politics, and ethics, guiding relationships between people, animals, and ancestors. Indigenous Cultural Mapping is a method that is frequently used to bring together Indigenous Knowledges and western scientific knowledge to support governance and assessment of Sea Country. The method is poorly defined in the literature which leads to inconsistent practice and outcomes. We undertook a scoping review and present the results to date here as part of the continuing aim to establish a working definition for Indigenous Cultural Mapping and provide recommendations on best practice in the literature to inform legislation, policy, and procedures.
