Party Representation Across States

Insight: Labor leads strongly in NSW and VIC, while the Liberal–National coalition performs best in Queensland — showing an urban–regional split.

Seat Change from Last Election

Insight: Labor records the strongest net gains. Liberal and LNP drive most losses; Nationals slightly down; independents/minors largely steady.

Urban vs Regional Strength

Insight: Labor is concentrated in urban seats; the Coalition’s ballast is regional (QLD/WA/SA/TAS/NT); Greens are predominantly metro.

Emerging or Growing Parties

Insight: Growth in 2025 concentrates in Labor. Most minor parties are flat/localised; Greens are steady rather than expanding.

Key Takeaways

  • Labor consolidates its urban base and posts clear seat gains.
  • The Coalition retains regional strength but city losses drive its net decline.
  • Smaller parties remain niche; independents are largely steady.
  • The city–region divide explains the national swing.

Ethical Reflection

  • Data integrity: Official AEC results; transparent cleaning steps.
  • Neutrality: Descriptive framing; proportional axes and clear labels.
  • Reproducibility: Full code embedded; published on RPubs for public access.
