One Nation has begun scouting Adelaide for its first permanent state headquarters outside Queensland, in the clearest sign yet that Pauline Hanson’s party intends to turn its South Australian electoral breakthrough into a lasting political operation.

The party is looking for a permanent office that would become an administrative and campaign hub for its rapidly expanding South Australian organisation.

For a party that has historically operated with a heavily centralised structure based in Queensland, the decision is significant.

One Nation is no longer simply sending candidates into South Australia at election time and hoping a national political wave carries them into parliament.

It is now attempting to build the machinery of a major political party.

South Australian One Nation president and upper house MP Carlos Quaremba has confirmed the party is examining potential locations for the new headquarters in Adelaide.

The office would be One Nation’s first permanent state headquarters outside Queensland and is expected to handle administration, campaign logistics, membership growth, merchandise and the development of local electorate branches.

“We’re now looking at setting up our first state office outside of Queensland,” Quaremba said.

The move follows One Nation’s extraordinary performance at the 2026 South Australian election, where the party collected more than 250,000 votes and emerged with seven MPs across both houses of parliament.

Four One Nation candidates won seats in the House of Assembly, while three representatives entered the Legislative Council.

The result transformed the party’s position in South Australian politics almost overnight.

Before the election, One Nation’s presence in the state was limited compared with the major parties.

Now it has a parliamentary team, a growing membership base and a significant pool of public funding.

The challenge facing Hanson is no longer simply attracting angry or dissatisfied voters. It is building an organisation capable of keeping them.

That is where a permanent headquarters becomes important.

Political parties are not sustained by polling numbers alone.

They require people to process memberships, manage volunteers, answer enquiries, organise events, recruit candidates, train campaign workers, distribute material and maintain relationships with local communities between elections.

Labor and the Liberal Party have spent generations developing those networks.

One Nation is now trying to build its own.

Quaremba has acknowledged the pressure created by the party’s sudden growth.

He currently holds several responsibilities within the South Australian organisation and has indicated a permanent office would allow One Nation to delegate more of the work required to run a growing political party.

The need for that infrastructure has become increasingly obvious as One Nation’s membership and grassroots activity have expanded.

Some party branch events have reportedly attracted crowds far larger than organisers expected.

In one example cited by the party, an event expected to attract about 30 people drew roughly 150.

That kind of turnout presents One Nation with both an opportunity and a problem.

A surge in political interest can disappear quickly if supporters have no local organisation to join.

People who attend a meeting, sign a membership form or volunteer for a campaign need to be connected with a functioning branch structure.

Without that infrastructure, enthusiasm can fade before the next election.

The proposed Adelaide headquarters is designed to help prevent that.

One Nation wants to establish electorate branches across South Australia, giving supporters a permanent local presence rather than a campaign operation that appears only when polling day approaches.

It is a strategy familiar to Australia’s major parties.

Local branches can identify potential candidates years before an election. They provide volunteers for doorknocking and polling booths. They organise community events and create relationships between elected MPs and local voters.

Perhaps most importantly, they allow a political party to maintain its identity during the long periods when national media attention moves elsewhere.

For One Nation, that could be crucial.

The party’s current national polling surge has placed it in political territory it has rarely occupied before.

One Nation’s support has climbed from about 6 per cent at the previous federal election to levels in the high 20s in some national polling during 2026.

The party has even challenged Labor and the Coalition for the lead on primary vote in individual polls.

But Australia’s electoral history is filled with minor parties that experienced dramatic surges before falling back.

One Nation itself knows that history better than most.

Hanson’s original political breakthrough in the 1990s produced enormous crowds and significant electoral support, particularly in Queensland.

The party then descended into internal turmoil, organisational problems and electoral decline.

Although Hanson eventually rebuilt One Nation and returned to federal parliament, the experience demonstrated the difference between a political movement and a durable political institution.

A movement can grow quickly around a charismatic leader or a powerful public issue.

An institution must continue operating when the headlines disappear.

The Adelaide headquarters suggests One Nation’s current leadership understands that distinction.

South Australia has become an obvious testing ground.

The party’s 2026 election result delivered something One Nation has long struggled to achieve consistently: lower house representation.

The ABC projected One Nation’s victory in Ngadjuri as the first time the party had won a South Australian lower house seat at a general election.

That breakthrough was followed by a broader parliamentary presence that gave the party a substantial platform inside state politics.

The result also exposed the depth of the crisis facing the South Australian Liberal Party.

One Nation’s rise came as conservative and right-leaning voters increasingly abandoned the traditional centre-right party.

Before the election, veteran electoral analyst Antony Green identified a dramatic shift in support on the political right, with One Nation gaining ground at the Liberals’ expense.

The pattern was particularly important in outer metropolitan and regional areas.

Those electorates are increasingly central to One Nation’s national strategy.

The party remains comparatively weak in many inner-city seats, where Labor and the Greens are stronger.

But Australia’s outer suburbs, regional cities and rural electorates contain dozens of seats that have traditionally been contested by Labor, the Liberals and the Nationals.

One Nation’s polling surge has disrupted those old calculations.

Political analysts have warned the next federal election could enter largely unknown territory if One Nation reaches the final preference count in a large number of electorates.

At the previous election, the party made the final two-candidate contest in only a relatively small number of seats.

If current support persists, One Nation could become competitive in scores of electorates.

That would create complicated preference contests that Australia’s major parties have little recent experience managing.

But high primary support does not automatically produce parliamentary seats.

This is another reason the South Australian headquarters matters.

A party needs strong candidates.

It needs campaign workers who understand local electorates.

It needs to identify booths where support is strong and areas where voters can be persuaded.

It needs volunteers capable of distributing how-to-vote cards and scrutineers who can observe the counting process.

Most of that work receives almost no national media attention.

Yet it can determine whether a political party converts 20 or 25 per cent of the primary vote into actual representation.

One Nation’s new South Australian operation is intended to build that capability.

The headquarters is expected to be supported by public funding available to the party following its electoral performance.

Australian political parties can qualify for taxpayer-funded election payments when candidates achieve the required level of support.

South Australia’s political funding environment has also undergone major changes, with tighter rules around donations increasing the importance of public funding for parties operating in the state.

One Nation’s strong vote gives it access to resources that were previously unavailable on the same scale.

The party now faces a choice about how to use that money.

It can treat the 2026 result as a one-off electoral success.

Or it can invest in the infrastructure required to fight future elections.

The Adelaide office makes One Nation’s choice increasingly clear.

It also raises questions about the party’s traditionally centralised structure.

One Nation has faced repeated criticism from former candidates and members over the way its national organisation operates.

Former party figures have accused the Queensland-based headquarters of exercising excessive control over candidates and state operations.

One Nation has rejected or disputed many criticisms of its internal structure.

But rapid national expansion inevitably creates pressure for greater local administration.

A political party with a handful of elected representatives can be managed from a central office.

A party with MPs and serious electoral ambitions across multiple states requires a different model.

South Australia may provide the first indication of whether One Nation is prepared to evolve.

Quaremba’s role will be important.

As both state president and a member of the Legislative Council, he is positioned between the party organisation and its parliamentary team.

The new office could allow administrative responsibilities to be distributed among staff and volunteers while MPs concentrate more heavily on parliamentary and electorate work.

That is standard practice for established political parties.

For One Nation, it represents another step towards professionalisation.

There is also a psychological dimension to establishing a permanent office.

A physical headquarters sends a message to members, potential candidates and political opponents.

It says the party expects to remain.

For South Australian Liberals, that message will be difficult to ignore.

One Nation’s electoral success has already changed the competition on the right of state politics.

The Liberal Party can no longer assume dissatisfied conservative voters will eventually return.

If One Nation establishes branches, recruits credible local candidates and maintains an active organisation between elections, those voters may develop a permanent political home elsewhere.

This is the deeper threat posed by Hanson’s expansion.

Polling surges can reverse.

A headquarters, branch network and parliamentary team are harder to remove.

They give a party the ability to survive a period of weaker polling and rebuild support.

Labor will also be watching closely.

One Nation’s support is often described as coming almost exclusively from the Coalition.

The electoral picture is more complicated.

The party has attracted voters from both sides of traditional politics, particularly in outer suburban and regional communities where concerns about cost of living, immigration, energy and trust in government can cut across old party loyalties.

At the South Australian election, One Nation demonstrated its ability to compete across a broad field by standing candidates in all 47 House of Assembly seats.

That level of candidate coverage is itself a major organisational task.

Maintaining it for future state and federal campaigns will require a permanent recruitment pipeline.

The Adelaide headquarters could become the centre of that operation.

It may also serve as a model for expansion into other states.

One Nation has already signalled ambitions beyond its traditional Queensland base, with the party targeting opportunities around the country.

If the South Australian office successfully builds branches, grows membership and supports elected MPs, similar permanent structures could follow elsewhere.

The Australian Capital Territory has recently appeared on the party’s political radar, while One Nation continues to examine opportunities in regional and outer metropolitan seats nationally.

For Hanson, the timing may never be better.

The Coalition is struggling to contain the loss of voters on its right flank.

One Nation has unprecedented polling momentum.

And the party’s South Australian election performance has provided something more valuable than another opinion poll: elected representatives and the funding that follows electoral success.

The question is whether One Nation can use this moment to overcome the organisational weaknesses that have repeatedly limited minor parties in Australian politics.

A new office in Adelaide will not answer that question by itself.

Buildings do not win elections.

Branches can collapse, candidates can fail and polling support can disappear as quickly as it arrives.

But the decision to establish a permanent headquarters reveals something important about One Nation’s intentions.

The party is no longer behaving as though its current surge is temporary.

It is investing in the assumption that Australia’s political realignment could last.

South Australia gave One Nation its breakthrough. Now Pauline Hanson’s party is building the machinery to make sure it does not give the ground back.
