A growing number of lower-house seats at Australian State and federal elections rely on a distribution of preferences from Independent and small-party candidates before seats can be awarded. Actors have attempted to gain political capital from this situation by claiming that the preferences of particular small parties have affected election outcomes. This paper uses the events of the Western Australian State election held in 2001 to explore the validity of such claims. More specifically, it investigates the widely propagated contention that the One Nation Party' s anti-sitting-member preference strategy was a key determinant of the Coalition's electoral defeat. It concludes that the increased number of candidates contesting elections makes it difficult to assess whether the second and subsequent preferences of any particular small party were critical to the outcome.
