Wonggu Mununggurr (c.1880–1959) was an Aboriginal Australian artist and leader of the Djapu clan of the Yolngu people of northeast Arnhem Land in the Northern Territory of Australia.
The friendship was sparked after Mununggurr's children were arrested and gave Thompson a "Måk" (message stick) to give to their father.
In return, Mununggurr gave a Måk back to Thompson to deliver to his sons as word of trust to the Yolngu people.

As the mission gained ground it sought funding from artwork made by local people, Wonggu Mununggurr included.
Now many of Wonggu Mununggurr's crayon works are held in the Berndt Museum of Anthropology of the University of Western Australia, Perth.
In conclusion to the Caldeon Bay Crisis, Donald Thompson was sent to the Northern Territory of Arnhem Land to investigate and hopefully deescalate the situation and stop the spread of similar causes throughout Australia.
From here, there was a strong connection between the Australian Aborigines and European governments, which in turn, sparked a friendly economic systems through commission for their bark art.
