Breaking: One Nation claims victory in Secret Harbour by-election

One Nation is asserting its victory in the Secret Harbour by-election, with counting indicating it is poised to achieve its maiden lower house seat in Western Australia. The party's leader, Rod Caddies, announced his party's triumph for candidate Luke Herdegen at 9.30pm local time, though Labor has not yet conceded. Labor's candidate was Georgia Tree, a former political staffer and Woodside lobbyist.

The region, historically a secure Labor stronghold since 1989, has been contested under various names and margins. Labor Premier Roger Cook had repeatedly described the by-election as a "fight for our lives" due to the perceived threat posed by One Nation. The significant swing against the Labor candidate in what was traditionally a Labor heartland is expected to be closely monitored across the nation, both as a measure of One Nation's support and a lesson on how to effectively campaign against such parties.
