Fast Fact Tag: boomerang shapes

No. “Boomerang” is better understood as a family of related regional implements than as one standard object. Size, weight, curvature, cross-section, edge shape and balance varied markedly according to place and purpose.

Nineteenth-century sources already recognised these differences. In 1878 R. Brough Smyth distinguished the returning Wonguim from the heavier non-returning war boomerang, Barngeet. He also contrasted Victorian boomerangs, which could weigh about ten ounces, with Western Australian kylies that were thin, sharply edged, angular in outline and often only about four ounces.

Later systematic classification makes the regional pattern even clearer. Australian Museum analysis identifies five dominant morphological groups — Common, Central Australian, Kimberley, Lake Eyre and Cooper Creek — together accounting for about 84% of specimens in the classification examined. The Central Australian form, for example, is asymmetrical and club-like and cannot return.

Even where boomerangs were used, therefore, there was no one-size-fits-all design. Regional environment, intended use, local tradition and trade all influenced what a “boomerang” looked like.
