Walka is Desert design and inextricably linked with Tjukurpa: the Law and way of life of Anangu (Central and Western Desert Aboriginal people). The symbols were traditionally used in cave, ground and body paintings, in story telling, teaching and signalling inheritance. Meaning of the designs depends on its subject and particular people are responsible for their re-creation and teaching according to the Tjukurpa. Highly experienced craftspeople have grown up making traditional tools and weapons under the instruction of their elders. They now apply this knowledge and express their world through art such as this.
