Aboriginal dance (also known as a corroboree) helps indigenous Australians to interact with the Dreamtime through dance, music and costume. Many ceremonies act out events from the Dreamtime. Many of the ceremonies are sacred and people from outside a community are not permitted to participate or watch. However, there are many ceremonies we've been allowed to witness (here's one of my favourites). And there's plenty of related pictures available at the National Museum's website. Naturally, any indigenous Australians reading should note that these links may include images or names of people who may now be deceased.
