The result was seen as an ominous sign for the Coalition, which has struggled to regain its footing following its resounding 2025 federal election loss, multiple internal leadership changes and two splits in the National-Liberal coalition agreement.Farley, speaking to cheering supporters on Saturday night, said One Nation had "reached the end of its beginning"."We're going through the ceiling from here," he added, while Hanson said the party was "coming after those other seats".Analysts have cautioned that by-elections can amplify protest voting and do not always translate directly to general election outcomes "In other words, there's no mystery what's going on here: a whole block of voters have said they're sick of the Coalition, and they're going to put their vote, at least in this by-election's case, towards One Nation."John Wanna, emeritus professor in political science at Australian National University, told SBS News One Nation's victory represented far more than just a protest vote."I think there is a grassroots revolt against the established parties," he said.The Coalition’s decision to preference One Nation ahead of other candidates in Farrer drew scrutiny during the campaign and intensified after the party’s strong result.Speaking on ABC's Insiders program on Sunday morning, shadow treasurer Tim Wilson repeatedly declined to say whether preferencing One Nation in Farrer had been the wrong decision
