Heather Koowootha draws inspiration from traditional ecological knowledge of plants passed down to her from her mother (of the Yidinji peoples, Yarrabah) and father (of the Wik Mungkan peoples, Aurukun). Koowootha explores the ritual significance of local native flora based on their medicinal and magical properties.

Her botanical illustrations held in the Cairns Art Gallery Collection reflect distinct knowledge systems and cultural practices established by both Koowootha’s parents and their Ancestors. Koowootha visually documents and describes various plants and their uses, incorporating hand-written text into her bold and colourful work. Her illustrations carry important knowledge associated with the medicinal and ritual uses of plants in birth, women’s business, marriage, death and other important ceremonies of the Yidinji and Wik Mungkan peoples.
