The Australian Electoral Commission questioned Pauline Hanson's One Nation party over more than $800,000 of claimed electoral expenditure for the last election, Guardian Australia can reveal. This was reported by Qazaqyia.kz citing The Guardian.

Documents obtained under freedom of information laws show that the inquiries prompted the party to withdraw more than 140 items as it sought to provide additional information to justify almost 15% of the party's $6.01m public funding claim.

The documents also reveal that the commission is now examining whether the party breached electoral funding laws for payments made to certain suppliers that were reimbursed in the claim.

As the party continues to rake in millions of dollars from supporters, and freshly banks more than $7m after its success at the South Australian election, the party's claim to taxpayer funds is being reviewed by the regulator for potential breaches.

Hanson, as the party's registered agent, would face criminal penalties if she submitted an "incomplete, false, or misleading claim" to a commonwealth entity, according to the declaration signed by the party leader that accompanied the claim.

One Nation has previously been found to have wrongly claimed public funding for electoral expenses and the party has twice been forced to pay back election funding – once after the 2019 election and again after the 2022 election.

In 2021 the AEC subjected Hanson to an enforceable undertaking, finding that as the party's registered agent, she had claimed about $165,000 in expenses that either was "not electoral expenditure" or was for spending "that had not been incurred".

The NSW Electoral Commission has also denied funding claims made by One Nation, finding in 2021 that it incorrectly claimed $118,000 in taxpayer funds for the purchase of electoral material, including merchandising.

The Guardian sought multiple documents One Nation lodged with the Australian Electoral Commission to justify the taxpayer funds it received under public funding arrangements after the 2025 federal election, and correspondence between the party and the regulator about its claim.

Based on the 6.4% national vote the party received at the last election and its Senate performance, One Nation received more than $6m in public funding from the AEC.

The released documents show that following the party's lodgement for just over $6m in July last year the commission queried information provided for 143 of One Nation's claimed expense items.

A senior compliance officer from the AEC raised questions with the party about its claim in late October, advising that more information was needed to justify and process the claim.

"Information can include further descriptions of the goods and services provided and what the dominant purpose of the expenditure was for," the compliance officer wrote in an October email to the party's operation manager, Alex Jones.

The officer requested the document be returned in the same week "so that we may continue processing the claim".

After a phone call about the queries, Jones, who is based at the party's Brisbane headquarters, advised that the party would "voluntarily withdraw" the items.

In an email, Jones said: "I wish to voluntarily withdraw the 143 items which have been queried totalling $809,648.11 from the party's interim claim, to allow us more time to assess the queries and provide appropriate responses for each in the party's final claim."

In November, the party submitted its final claim, however details of this, including its response to the 143 queried items, have been redacted under freedom of information laws.

The decision to refuse the release of certain documents to the Guardian, including two key documents that detail the party's funding claim, is based on the AEC's compliance review of the payments made to One Nation. The AEC also examines funding claims made by other political parties as a matter of routine.
