Terminology
Due to a disciplined coalition between the parties and their predecessors being in existence for almost 100 years with only a few brief cessations within a parliamentary system, most commentators and the general public often refer to The Coalition as a single party. Polling and electoral results contain a two-party-preferred (TPP) vote which is based on Labor and the Coalition. The Australian Electoral Commission has distinguished between "traditional" (Coalition/Labor) two-party-preferred (TPP/2PP) contests, and "non-traditional" (Independent, Greens, Liberal vs National) two-candidate-preferred (TCP/2CP) contests. At the 2010 federal election, all eight seats which resulted in a two-candidate-preferred result were re-counted to also express a statistical-only two-party-preferred result.
