The Western Australian branch of One Nation has disclosed receiving donations solely from a single supporter amid its campaign for the upcoming Secret Harbour by-election. Party leader Rod Caddies confirmed the organization has met all state requirements for donation disclosures, revealing a $25,000 contribution from Grower Connect Pty Ltd, a Manjimup-based company owned by farmer Paul Da Silva. This donation follows a previous $50,000 gift from the same entity to One Nation WA in April.

The Secret Harbour by-election, triggered recently, has become a focal point for One Nation, which is positioning itself as a strong contender against the incumbent Labor party. Despite federal leader and party founder Pauline Hanson’s recent visit to Perth for a "Fire the Liar" fundraising event that reportedly raised over $1 million in a day, Caddies emphasized that those funds were intended for the federal branch of One Nation and not the Western Australian arm. He also said One Nation WA has not received financial assistance from the federal party, instead operating a modest grassroots campaign locally.

Caddies dismissed speculation about funding from prominent figures such as WA iron ore magnate Gina Rinehart, stating that One Nation WA does not receive donations from her or from the party’s national headquarters. Under Western Australian law, political donations exceeding $2,900 must be disclosed within seven days, or within 24 hours if an election writ has been issued. Aside from the donations from Grower Connect, One Nation WA has disclosed fewer large donations over the past four months compared to smaller parties like Legalise Cannabis, the Animal Justice Party, and Australian Christians.

Caddies noted that One Nation WA’s fundraising strategy largely depends on smaller donations generally falling below the disclosure threshold and expressed satisfaction with managing the campaign without federal support. The party’s candidate for Secret Harbour, gym owner Luke Herdegen, was presented as a grassroots representative with no reliance on large handouts.

In contrast, the Labor party continues to dominate the political fundraising landscape in Western Australia, largely due to significant contributions from unions such as the United Workers Union and the Shop, Distributive and Allied Employees Association. Labor has disclosed $1.7 million in donations since April, an amount that exceeds the combined total raised by all other parties in the state. The Greens in WA rely heavily on substantial gifts from private donors, notably Cottesloe resident Ruth Greble, as well as a $13,449 donation from the Australian Greens following the issuance of the Secret Harbour election writ.

WA Labor state secretary Mark Reed criticized One Nation for what he described as a lack of transparency during the by-election campaign. Reed accused the party of avoiding public scrutiny by withholding policy announcements and keeping campaign finances opaque. Labor’s spending on advertising in the lead-up to the election has surpassed One Nation’s, with over $13,000 spent on Facebook ads in the past month compared to One Nation WA’s $3,400. Premier Roger Cook and Labor’s candidate for Secret Harbour, Georgia Tree, remain actively engaged in campaigning efforts.
