History

Western Australian Senate races were dominated by the Coalition from 1951 until the beginning of the 1980s. The 1951 election produced a result of four ALP senators, four Liberal senators and two Country Party senators.  The 1953 election saw the ALP win a seat off the Country Party, but the previous result was restored in 1955. The 4-4-2 result was maintained at every election throughout the 1950s and 1960s. The 1970 Senate election saw the Liberal Party lose one of its four seats to independent Syd Negus, who was elected on a platform of abolishing death duties.

The 1974 double dissolution saw Negus defeated and the Country Party lose one of its two seats. The result saw five Labor senators alongside four Liberals and one Country senator. The 1975 double dissolution saw the Coalition regain its majority in Western Australia, with the ALP losing its fifth senate seat to the Liberals. The 1977 election saw the National Country Party lose its senate seat to the Liberals, producing a result of six Liberals and four Labor senators.

The 1983 double dissolution saw the Liberals lose their majority, with five Liberals, four Labor and one Democrat elected. The 1984 election saw Labor gain both new Senate seats while the Democrats lost their seat. In addition to 6 ALP and 5 Liberal, the Nuclear Disarmament Party’s Jo Vallentine was elected. At the 1987 double dissolution, Vallentine was re-elected as an independent along with a Democrat and five each for the two major parties.

The 1990 election saw the Liberals win six seats, along with five Labor and the re-elected Vallentine, who was re-elected as a Green. The Liberals have maintained six WA seats ever since. The 1993 election saw the Greens win a second seat off the ALP. From 1993 until today, WA has been represented by six Liberals, four Labor senators and two minor party Senators from the Greens or Democrats.

In 1996, the Greens lost one of their seats to the Democrats, losing their other seat in 1998. The Democrats held onto their seat in 2001 before losing one of their seats in 2004. The last Democrat was defeated by the Greens candidate in 2007.

The Liberal Party won three seats on primary votes and the ALP won two. After preference distribution, the last four candidates standing were Scott Ludlam of the Greens, Gerard Goiran of the Christian Democratic Party, #3 ALP candidate Ruth Webber and #4 Liberal candidate Michael Mischin. They each had the following number of votes:

  • Ludlam (GRN) – 0.7612
  • Webber (ALP) – 0.5270
  • Goiran (CDP) – 0.4607
  • Mischin (LIB) – 0.2498

Mischin was excluded, and the vast majority of his preferences flowed to Goiran of the CDP, producing the following count:

  • Ludlam – 0.7669
  • Goiran – 0.7015
  • Webber – 0.5300

Webber was then excluded, and her preferences elected Ludlam, and the final count was:

  • Ludlam – 1.2917
  • Goiran – 0.7062

Political situation

Western Australia is the weakest state for the ALP, based on 2007 figures. The Liberals clearly came first in the Senate vote in 2007, outpolling the ALP by 10%. It is also the one state where the Greens are at risk of losing a seat, regardless of whether the election is called as a half-Senate election or a double dissolution. In the case of a half-Senate election, a swing to the ALP away from the Coalition puts Rachel Siewert at risk of being squeezed between three quotas for each of the major parties, in a similar way that Kerry Nettle was defeated in NSW in 2007.

If the Greens manage to increase their primary vote by about 3.4% of the vote through swings away from the major parties, they should be able to be elected with major party preferences. Short of that, the following swings between the major parties (ignoring the Greens vote level) would result in a seat change from the current 3-2-1 split:

  • A 10.2% swing from Liberal to Labor would give the ALP a third seat at the expense of the Liberals.
  • A 4.3% swing from the ALP + Greens to the Liberals + CDP would give the Liberals/CDP a fourth seat at the expense of either the Greens or Labor, depending on vote levels for CDP and Greens candidates.
  • A 1.3% swing from Liberal to Labor would give the ALP a third seat on primary votes, locking out the Greens.

Using primary vote levels from 2007, a double dissolution would produce a clear result. The Liberals would hold their six seats, the Greens would hold one of their seats, the ALP would hold their four seats and the fifth ALP candidate would be in a very strong position to win the last seat, costing the Greens one of their two seats. A 6.8% swing from the combined right-wing vote to the ALP + Greens would be needed to allow the Greens to hold their second seat at the expense of the Liberals.
