Love magic in its various forms plays an important part in personal economic transactions among Aboriginal men in the Kimberleys. Indigenous local forms have now virtually disappeared, and today this kind of coercive magic and its associated objects are mainly derived from south and east of the Kimberley bloc. There are three major classes of object associated with love magic. First, a variety of substances including red and white ochrous rocks and powders, small pieces of rotten wood, sometimes crushed human bones obtained from old burial sites, and very occasionally a charm made from a finger bone or other small bone. All these are referred to as tjirri. Second, rare pendants worn in public, each bearing an individual name, but known collectively as tjirri. Third, small wooden objects of bullroarer type usually derived from the desert tribes to the south and south-east of the Kimberleys. We shall refer to these as 'bullroarers' because their collective name is regarded by Kimberley Aborigines as a sacred word unsuitable for publication. Tjirri is the most commonly used magic substance in the Kimberley. Its use is not exclusive to either men or women, and no sexual restrictions appear to be associated with it. As well as being sought for amorous reasons, tjirri is acquired to attract good luck. Commonly tjirri is used by men for love magic while women usually use it for luck at cards, although we know of several cases in which girls used such substances to attract lovers.
