The Formation of the Queensland Liberal National Party: Origins, Prospects and Implications for Australian Political Systems.

In Australia, two‐and‐a‐half party systems are common with the Liberal and National parties, usually needing to collaborate to form governments. In Queensland, the 2008 merger of two of these state parties to create the Liberal National Party (LNP) created instead a two‐party system. This review examines the forces for the merger and prospects for the continuation of the LNP, the likelihood of change as a result of the Queensland merger in the remaining two‐and‐a‐half party systems, and how the drivers of this merger compare with those observed in studies of other non‐Australian party and electoral systems. Pressures and conditions for a merger similar to those in other, mostly European systems, were evident in the case of the LNP. The particular structure of the pre‐merger party competition and relationships was, however, a likely factor in the merger in that two collaborating parties could avoid a contested switch in party seniority. This aspect, unlikely to occur in other Australian party systems, combined with the very limited success of the LNP in gaining and holding government since the merger, does not suggest an imperative for further mergers in other Australian systems.
