Voters in Western Australia have two years until their next State election. The last election occurred in 2021, and the Labor Party won overwhelmingly. At first glance, it doesn’t look like losing power, unless something dramatic happens. Then again, the Liberal Party had easily won an election in 2013 before a big swing in 2017 saw it lose power.
But the next election will have something very different, regarding the Upper House of Parliament.
Apart from a crushing victory in the Lower House, with more than 50 of 59 available seats won there, Labor won also won a majority in the Upper House. This chamber is where minor parties generally fare better, because they only need a certain percentage of the vote in order to win seats, rather than anything near a majority. But in 2021, Labor won a majority, and then reformed the chamber.
In 2025, when the next election comes, the Upper House will consist of 37 seats, with the whole State treated as a single electorate. This will differ from how it looks at the moment, with 36 seats spread across several regions. Parties need a certain percentage of the vote across each region to win seats, whereas in 2025 this percentage will refer to the entire State and make seats easier to win.
It doesn’t matter whether candidates live in Kununurra, Karratha, Kalgoorlie, Katanning, Kelmscott, Karrinyup, or Kingsley. If they or their parties win about 2.6 per cent of the statewide vote in 2025, they’ll be guaranteed an Upper House seat.
Where does this percentage come about? The answer is that when calculating how much of the vote you need, you divide the total vote by a number which is one more than the number of seats actually up for grabs across the jurisdiction. It doesn’t matter how seats are there.
In the case of the reformed Upper House, with 37 seats available, it’ll be a case of dividing the total votes cast by 38, before adding an extra vote to that. This equals about 2.6 per cent of the vote. You can alternatively just divide the total votes cast by 38, to get a rough idea.
Perhaps this will make the reformed Upper House closest to an accurate measure of popular support that political parties really have. The major parties tend to poll more strongly in Lower House seats, because parties and candidates need to win large shares of the vote, though not necessarily a majority, within clustered areas, such as a handful of suburbs in a capital city or a large group of towns. About 35-40 per cent of the vote gives candidates a chance, but minor parties normally struggle to win that level of support locally. Upper House contests are easier for them.
At the moment, the Upper House of Parliament in New South Wales comes closest to showing how much support political parties really have. With 21 seats up for grabs there at election time, parties only require about 4.5 per cent of the vote to win seats. The next closest would be in South Australia, with 11 Upper House seats up for grabs and about 8.3 per cent of the vote required to win seats.
I might wonder if minor parties in particular might think of heading west to find easier parliamentary contests. With the percentage of the vote required for election pretty low, the temptation is there.
Based on the last election results, Labor would’ve won at least 22 seats, with 60.3 per cent of the vote across WA. Less than 38,000 votes statewide would’ve won somebody a seat.
Previously, when Labor took power in WA in 2017, it would’ve taken at least 15 Upper House seats, with 40.4 per cent of the vote. But at the election prior, in 2013, which it lost, its tally would’ve been 12 seats, with 32.5 per cent of the vote. The Liberals, in winning that 2013 election, would’ve taken 18 seats, with 47.6 per cent of the vote.
This arrangement for 2025 will be naturally different from how the Upper House is arranged now.
With six regions returning just six members each, each party needs a larger share of the vote to take seats. But some regions, especially around the State capital, contain hundreds of thousands of voters, in contrast to just tens of thousands elsewhere.
Voters in rural and remote locations will probably feel marginalised. But doesn’t their existing power seem disproportionate to their numbers, when most voters live around the State capital? Then again, might a better population policy and better infrastructure entice more people to move to the regions, thereby potentially making support increase for political parties who claim to care about the regions?
Regardless of what both urban and rural voters think about the reformed Upper House in WA, their opportunity to pass judgement on it will come in 2025. Minor parties in particular may be motivated to put more efforts into the 2025 election, with an easier opportunity to win parliamentary seats and give exposure to the issues that spur them to run.
