Thirty years ago, against the odds, a fish-and-chip shop owner with little political experience won a seat in the Australian parliament. Since then, Pauline Hanson has become as well known for her inflammatory anti-immigration rhetoric as much as her parliamentary stunts, while support for her right-wing populist One Nation party has ebbed and flowed. However, after returning from the political wilderness a decade ago, Hanson's party is now riding a new wave of popularity, driven by voters weary of mainstream political parties that they say don't understand their struggles.

On 21 March, One Nation achieved its first electoral breakthrough outside Hanson's home state of Queensland during the South Australia state election, winning the second-highest number of votes - more than 20% - marking a historic moment in a landscape traditionally dominated by two major parties. While the incumbent Labor Premier Peter Malinauskas won a decisive victory, One Nation will see at least three candidates elected, primarily at the expense of the main opposition Liberal Party.

As the Liberals struggle, and populism gains traction globally, analysts question whether this election marks One Nation's shift from the political fringes towards the center. Kos Samaras, a former Labor strategist, flags this trend as a troubling sign for Australia's established political parties.

Historically, One Nation has been synonymous with its anti-immigration policies, a sentiment echoed in Hanson's infamous 1996 parliamentary debut, where she claimed Australia was 'in danger of being swamped by Asians'. In the years following its polarizing rise, One Nation has generally floated in low support percentages after an initial wave of acclaim in the late 90s. However, recent political turmoil, including a widespread cost-of-living crisis and internal conflict within the Liberal Party, has opened doors for a resurgence, capturing significant attention across Australia.

The party's recent electoral performance is largely attributed to disenchanted voters grappling with everyday issues such as housing affordability, an angle resonating with disgruntled Australians. Notably, voters like Brittany, a long-time supporter of the Liberal-National Coalition, are now drawn to One Nation's promise to address housing supply and curb immigration.

Discontent among voters, particularly older generations, plays a pivotal role in the party's rise. It paints a broader picture of voters seeking alternatives amidst feelings of neglect by major parties. Importantly, this electoral gain by One Nation doesn't come without fears; communities from diverse backgrounds express concern over rising sentiments of racism and division fueled by Hanson's rhetoric.

Looking to the future, the question remains: Can One Nation solidify its gains, navigating historical challenges tied to candidate selection and internal strife? Observers assert that while the party may currently thrive, its long-term success in Australia's unique electoral landscape is uncertain, especially given voter fragmentation and core discontent towards traditional political elites. Regardless of debate, Hanson emphasizes her party's determination to extend its influence, capturing the sentiments of those ready for a change.
