Summary Nature conservation in both theory and practice is increasingly looking to understand different knowledge systems, including Indigenous worldviews, to achieve complementary conservation and socio‐cultural goals. Here, we share stories from one of the longest running Indigenous Protected Areas (IPAs), Walalkara IPA, by Langaliki Robin, daughter of the founders of the IPA, who reflected on her parents’ lessons about how Tjukurpa (Dreaming Law) is essential for conservation. Grounded theory analysis of her interview identified the importance of Tjukurpa and the role of Langaliki’s parents, particularly her father Tjilpi Robin Kankapankatja in the establishment of the IPA. Tjukurpa was asserted as a core cultural knowledge system that provides Indigenous people with motivation, strength and well‐being, allowing them to maintain access to Country and work cross‐culturally. Tjukurpa influenced the initial declaration, roads and physical layout of the protected area and continues to guide the daily work activities of IPA rangers. According to Langaliki, the key to maintaining strong people and Country is to pass on cultural knowledge and Tjukurpa from generation to generation, especially to younger people. This research suggested that by knowing who the key knowledge holders are, respecting that Tjukurpa exists without being privy to the details, and continuing multi‐generational access to Country, conservation programmes that embrace Indigenous ways of knowing and doing can achieve successful outcomes for nature conservation and Indigenous well‐being.
