The Greens are hoping for another ‘greenslide’ election. What do the polls say?
- Written by The Conversation
Election talk is inevitably focused on Labor and the Coalition because they are the parties that customarily form government.
But a minor party like the Greens is consequential, regardless of whether the election delivers a minority government. Certainly, the level of anti-Greens campaigning by third party groups, like Better Australia, suggests as much.
The Greens’ have declared that their electoral aim is to “Keep Dutton out and get Labor to act”. They know this would be best achieved in a minority government, where the crossbench would be powerful players.
But can the Greens build on their historic 2022 election result, which delivered four lower house seats and the balance of power in the Senate?
State of play
An aggregation of the main polls estimates the Greens’ nationwide primary vote has ticked up since 2022, now ranging from 12.4% to 14.1%.
They are expected to retain all six Senate seats up for election. When combined with their five other Senate seats, the party will be critical in the next parliament to the fate of legislation in the red chamber.
In the contest for the House, the Greens are defending a record four seats: Melbourne, Brisbane, Griffith and Ryan. Melbourne is held by party leader Adam Bandt, on a comfortable 8.5% margin. It is as safe as it gets for the Greens.
The balance of the party’s seats are all Brisbane-based, starting with Ryan, which is held by just 2.6% if the two-party preferred vote. Despite the slender margin, Ryan has better prospects than the neighbouring seat of Brisbane, which it holds by 3.6%. This is based on the party’s 2022 swing of almost 10%, which placed them second in Ryan on primary votes.
In contrast, the Greens finished in third position on primary votes in Brisbane on the back of a respectable, but much more modest swing of just under 5%. The electoral dynamics are also complicated because the seat is a genuine three-cornered contest.
On the other hand, Griffith is now classed as a safe seat for the Greens. The party attained the highest number of primary votes (34.6%) on the back of a 10.94% swing three years ago. The Greens should be able to defend Griffith.
Target seats
The Greens have declared five additional electorates as “priority target seats” – two in Victoria and one in each of New South Wales, South Australia and Western Australia.
Wills is the first of two Melbourne-based seats earmarked by the Greens. The party is betting on a redistribution in the Labor held seat, which independent analyst The Poll Bludger estimates will reduce the ALP’s primary vote by 2.6% and increase the Greens’ vote by 5%. The Greens are also fielding a high profile candidate, former state MP Samantha Ratnam.
In the case of Macnamara, the Greens finished in second position behind Labor in 2022. At the point of the Greens’ exclusion in the count they were on 32.84%, just marginally behind Labor on 33.48%
While the Greens’ prospects might be helped by a weakened Victorian Labor brand, victory could still prove elusive. In the case of Macnamara, the electorate takes in parts of the state seat of Prahran, which the party lost in a byelection in February. The by-election was precipitated by the resignation of the state Greens MP owing to allegations of inappropriate conduct with an intern.
Moreover, Liberal how-to-vote cards in both Wills and Macnamara are preferencing Labor over the Greens, which may be enough to push Labor over the line in both seats.
Chances elsewhere
The NSW seat of Richmond is a marginal Labor electorate that was once held by the Nationals. The Greens are calculating the seat is winnable based on their strong primary vote in 2022 and candidate continuity.
Richmond boasts one of the highest levels of rental stress in the nation, making it a perfect setting for Greens campaigning on housing affordability issues. Polling shows the Greens vote is up by 3% in NSW. If it’s accurate, and translates to Richmond, then the seat is potentially winnable.
Sturt in South Australia is the Liberal Party’s second most marginal seat (0.5%). However, the likelihood of a Greens victory is slim. At the 2022 election the Greens attracted only 16.39% of the primary vote, well behind both Labor and the Liberals.
The party’s final target seat is Perth, held by Labor on a very safe 14.4%, two party preferred. The seat’s demography explains why it’s a Greens priority. Perth is a relatively affluent inner metropolitan seat, with a high percentage of people who finished school, and a constituency that skews young.
But Perth is unlikely to turn to the Greens. In 2022 they finished in third position on primary votes (22.16%), well behind Labor (39.25%). The party’s Perth campaign may have also been damaged by plans, since abandoned, to hold a fundraising event on ANZAC Day.
Numbers game
Based only on the seats examined, the Greens will likely retain at least Melbourne and Griffith in the lower house, along with the 6 senate seats it is defending.
A more optimistic reading of the polling would also include Ryan, Brisbane and Wills. A best case scenario would also add Richmond and Macnamara to that list.
And then, of course, there are the unexpected victories that many of us simply don’t see coming. This is because party support and voter swings are never uniform at the seat level. There will be electorates that under-perform for all parties. And that includes the Greens.
