The late R. Lamilami1 had a rich and remarkable life, engaging in many activities and career paths to benefit his community, including working for the Northern Land Council, Kakadu Health Services and participating in health research (e.g. Kirkham et al. 2019). He was a senior Mawng (Maung) elder and Traditional Owner, well respected as a cultural leader across Arnhem Land and beyond. He had a passion for his traditional lands, especially his clan estate Namunidjbuk, Wellington Range, northwest Arnhem Land (Figure 1), as well as cultural heritage and history. But although he wanted them protected from any sort of natural or human-made threat he also was keen to share his culture and heritage with the outside world. He believed that, through education and raising awareness about the importance of his cultural heritage, other people would help him look after it for future generations.
