一国党在西澳秘密港补选中创造历史，劳工党遭遇重创

一国党候选人Luke Herdegen在西澳州秘密港补选中取得历史性胜利，首选票率达39.1%，击败劳工党候选人Georgia Tree的24.4%1。最终计票显示，一国党以57.0%对43.0%的比例获胜2。这标志着一国党首次从劳工党手中赢得该席位，也是该党在西澳州获得的首个下议院席位1。

劳工党在秘密港遭遇18.6%的摇摆1，首选票率从2025年3月州选举的61.5%跌至24.4%2。西澳州总理Roger Cook表示"秘密港的选民已经发表了看法，我们将倾听"1，承认高生活成本是关键议题。一国党联邦议员Barnaby Joyce指出，传统劳工党席位不能再被认为是理所当然1。分析人士Kevin Bonham指出，秘密港及其前身席位一直是劳工党相对于自由党的安全席位2。

这一结果反映出一国党在传统劳工党票仓中的上升势头，特别是在职业资格教育程度较高且族裔多样性较低的地区2。此前，一国党在南澳州3月选举中获得四个下议院席位，在联邦议会5月Farrer补选中获得一个席位1。

One Nation has achieved a landmark result in Western Australia, winning the state seat of Secret Harbour with 39.1 percent of first-preference votes, defeating Labor's Georgia Tree who received 24.4 percent.12 The party's candidate Luke Herdegen secured the seat with a final two-candidate-preferred count of 57.0 percent to Labor's 43.0 percent.2 This marks the first time One Nation has won the seat from Labor, representing a significant 18.6 percent swing against the incumbent.1

Western Australia Premier Roger Cook acknowledged the result, stating "the voters of Secret Harbour have spoken and we will listen," recognizing high living costs as a key issue driving voter sentiment.1 One Nation federal MP Barnaby Joyce emphasized that traditional Labor seats can no longer be taken for granted.1 The victory signals One Nation's growing penetration into traditionally safe Labor territory, particularly in areas with higher vocational qualification rates and lower ethnic diversity.2

The by-election loss extends Labor's recent electoral difficulties. In the March 2025 state election, Labor won 46 of the 59 lower house seats, but the Secret Harbour seat had shifted dramatically from a comfortable 61.5 to 38.5 percent Labor advantage over the Liberals.2 One Nation's performance represents a 30.6 percentage point improvement from the March state election, while Labor's primary vote fell 22.1 points.2 This result follows One Nation's capture of four lower house seats in South Australia in March and a federal by-election victory in Farrer in May.1
