Pre-parliamentary backgrounds of Australian major party MPs: effects on representation

Legislative recruitment patterns are an important study in the field of political science, given their consequences for the practice of parliamentary government. The Australian parliament is a bicameral legislature, including a powerful elected upper chamber. This article details the pre-parliamentary party backgrounds of Australia's two major parties, the Australian Labor Party (ALP) and the Liberal/National Party coalition (LNP) in the 39th Australian Parliament (1998–2001). It is hypothesised that the pre-parliamentary backgrounds of Upper House major party MPs are dominated by central party experience, while the party experience of Lower House MPs is more significantly localised. It is further hypothesised that these differences in pre-parliamentary backgrounds will remain constant when the respective parties are evaluated individually. This appears something of a paradox given that one would expect central party activists to prefer a legislative career in the lower house, affording them greater ministerial opportunities. The causes of such deviations from expected background distributions amongst legislators is explored. Contrary to traditional findings, upper house MPs are highly partisan, performing functionary roles to assist their lower house colleagues secure re-election. Strong senator partisanship is reflected in the non-parliamentary practice of major party senators. Such partisanship is a consequence of party selection methods, the electoral system and pre-parliamentary party backgrounds, not necessarily the uniquely powerful Australian Senate. It is therefore significant in the Australian polity and may have consequences for less powerful and/or unelected upper chambers in other bicameral parliaments.
