Tjukangku was one of the first men to begin painting at Indulkana, and was one of the original members of Iwantja Arts. In addition to painting, he also does printmaking using the intaglio method (cutting designs into wooden objects). Beginning in his early 70s, Tjukangku is reported to suffer from dementia. He still works as a full-time artist, however, and makes an average of one or two artworks per week.
