A mia-mia is a temporary shelter made of bark, branches, leaves and grass used by some Indigenous Australians. The word is also used in Australian English to mean "a temporary shelter". It comes from the Wada Wurrung language. The term is also used in New Zealand, where it is usually spelt mai-mai and has the slightly different meaning of a shelter or hide used by a duck-hunter.
