Who will win the next Australian House election 2028

Specific quarter-over-quarter trends for marginal seats are unavailable. The provided research does not offer detailed quarter-over-quarter two-party preferred (2PP) vote trends for the 10 most marginal seats identified from the 2022 federal election pendulum ^[4]. While specific percentage figures or historical comparisons for these marginal seats were not detailed ^[1], a Newspoll report from May 2024 indicated that Labor was "surging in poll of marginal seats" ^[1].

National Newspoll data indicates a steady Labor lead. In June 2024, Newspoll reported Labor's two-party preferred lead over the Coalition as steady at 52-48 ^[2]. This national Newspoll figure was consistent with reporting from late May 2024, which also described the Newspoll results as "steady" ^[1].

National surveys generally show Labor ahead of the Coalition. Resolve Political Monitor data from June 2024 indicated Labor "surges ahead" in national surveys ^[5]. More recently, by August 2024, both Newspoll and Resolve Political Monitor indicated that Labor was "well ahead" of the Coalition nationally ^[3].

Specific net approval data for WA and Queensland is unavailable. While direct net approval ratings for Prime Minister Anthony Albanese and Opposition Leader Peter Dutton in Western Australia and Queensland are not provided in the available web research, national trends and state-specific primary vote trends offer insight. Following the 2025 federal budget announcements ^[2], Prime Minister Albanese's national net approval rating saw an improvement, increasing by 3 percentage points from -17 points to -14 points ^[1]. In contrast, Peter Dutton's national net approval rating deteriorated by 3 points, reaching -12 points ^[3]. Immediately post-budget, national polls showed Albanese's approval rising to 39% while Dutton's fell to 37% ^[1]. Regarding state-specific sentiment, which is measured by primary vote, Labor experienced a significant boost. In Western Australia, Labor's primary vote jumped by 6 points to 37%, with the Coalition's dropping by 3 points to 33% ^[1]. In Queensland, Labor's primary vote increased by 5 points to 34%, while the Coalition's fell by 3 points to 37% ^[1].

National and state sentiment notably shifted by early 2026. By this time, Prime Minister Albanese's national net approval plunged to -21 points ^[4]. This decline was also evident in state-level primary votes. In Western Australia, Labor's primary support dropped 7 points to 30%, and in Queensland, it fell 6 points to 28% ^[4]. The Coalition's primary vote, however, remained steady at 40% in Queensland during this period ^[4]. The available research primarily links these changes in approval and primary vote to federal budget announcements. While the Reserve Bank of Australia (RBA) conducts monetary policy board meetings ^[5], the provided sources do not explicitly detail any direct impact of specific RBA interest rate decisions on Albanese's or Dutton's approval ratings or party primary votes at either a national or state level.

The Liberal Party reclaimed two key independent-held electorates in the 2025 federal election. The party successfully won back Goldstein and North Sydney from their incumbent independent members ^[1]. This included Tim Wilson's victory in Goldstein, described as "turn[ing] back the Teal tidal wave," which indicates a significant swing towards the Liberal candidate in that seat ^[2]. Reports similarly confirmed the loss of North Sydney for the 'Teals' ^[1].

However, a comprehensive picture across all key independent-held seats is not available. While the reclamation of Goldstein and North Sydney demonstrates the Liberal Party's ability to achieve electoral swings in specific instances, the provided research lacks detailed 2025 election results or post-election primary vote trends for other significant independent-held electorates, such as Kooyong, Wentworth, Curtin, and Mackellar ^[3]. Therefore, based on current polling and available information, it is not possible to conclude if the Liberals are broadly "on track" to regain the necessary 5-8% swing in all remaining independent-held electorates ^[4].

Greens voters consistently preference Labor at high rates. When the Australian Greens are excluded from the final count, approximately 85% to 90% of their preferences typically flow to the Labor Party. For example, in the Queensland 2024 state election, 84.7% of Greens' preferences went to Labor, with the remainder flowing to the Coalition ^[1]. This aligns with broader trends indicating that nearly 90% of Greens voters preference Labor ^[2], and historical data from 2010 showing an 88.6% flow to Labor, with similar rates anticipated for the 2025 federal elections ^[3].

One Nation voters show a clear preference for the Coalition. In the Queensland 2024 election, when Pauline Hanson's One Nation (PHON) was excluded, 63.8% of their preferences flowed to the Coalition, while 36.2% went to Labor ^[1]. This demonstrates a substantial, though not overwhelming, preference for the Coalition among PHON voters ^[4], providing insight into recent electoral dynamics and the distribution of preferences when minor parties are excluded from the final two-candidate preferred count ^[1].

A "double dissolution" election is triggered by Senate rejection of legislation. This occurs in Australia when a proposed law, having passed the House of Representatives, is rejected, substantially amended, or not passed by the Senate. If, after a three-month interval, the same bill is again passed by the House and once more rejected, unacceptably amended, or not passed by the Senate, it becomes a double dissolution trigger ^[2]. The most prominent current legislative trigger discussed in the Senate context relates to proposed housing legislation, specifically a bill concerning a $100 million crisis fund. Reports indicate a double dissolution election threat is being revived in parliament over this housing dispute ^[1].

Political betting markets do not directly imply an early election probability. While the research requested the probability of an early election before the scheduled 2025 date, as implied by political betting markets, the provided web research results do not explicitly contain these specific odds. The available sources include links to prediction markets referencing events such as "Next Government of Australia Predictions & Odds 2026" and "Anthony Albanese out as Prime Minister of Australia by......" ^[3]. However, these market listings, as provided, do not offer direct probabilities for an early election (before 2025) specifically resulting from a double dissolution trigger.
