A common motif featured in Tjukangku's artworks is "puṉu" (wood that is used for making traditional tools and objects). This is often both his subject and his medium. Objects in his artworks are often more figurative (realistic) than in most Western Desert art, but still contain elements and shapes that are very clearly abstract. Tjukangku paints in natural earthy tones, using rich shades of red, browns, ochres and black. He uses fields and lines of white dots to highlight shapes and movement. Tjukangku's work has been featured in group shows at major galleries since 2010. He held his first solo exhibition in April–May 2011, in Alice Springs. He held a second solo show at the same venue the next year, in July–August 2012. One of the works exhibited at his first solo show was bought by the National Gallery of Victoria in Melbourne. Other works by Tjukangku are held in several of Australia's major private galleries. Some of his earliest prints are displayed in the South Australian Museum.
