The mimih spirit exists in a realm that runs parallel to and mirrors many facets of human life, also demonstrating the deep sense of time and place understood by Aboriginal and Torres Strait Islander people. Such spirits feature importantly in relation to Aboriginal spirituality, cosmology, social and moral tales as well as ritual.

Contemporaneously, mimih are depicted in a refined, slender, even emaciated form with a broad range of facial expressions giving both individual character to, and denoting the potential volatility and humour that mimih spirits are notable for in their interaction with binin; (humans). The sculptures are frequently carved from the thin trunks of softwoods such as kapok (bombax ceiba or cottonwood) kurrajong, beach hibiscus or leichardt and are painted with earth pigments for their colouring and design.
