Nayombolmi or Najombolmi, who was also known as Barramundi Charlie (c. 1895 – 14 August 1967) was a Badmardi (Bininj) and Jawoyn man born at Balawurru, in the Adelaide River region, of the Northern Territory.

He spent his early years living with his family on Badmardi Country and learned to speak many languages and dialects as well as the required bush skills and cultural knowledge.

[5] It is not recorded what happened to Nayombolmi during World War II but as of the 1950s he was working as a stockman at Barramundie Station and at a timber camp at Manlarr (Kunwinjku) which were both nearby to Jabiru.

[1][6] The Anbangbang Gallery includes some of the most iconic rock art imagery from Australia and is visited by hundreds of thousands of tourists each year.

[12] One of Nayombolmi's bark paintings was included in the National Museum of Australia's Old Masters exhibition in 2013 and one of his rock art figures was reproduced on the bicentennial $10 note in 1988 (Australian).
