One Nation has disendorsed its candidate for the seat of Brisbane, Rebecca Lloyd, saying she has shown an "unwillingness to work with and follow direction from One Nation's national executive".
The move to dump Ms Lloyd came after the ABC revealed a website she registered was under investigation by the Australian Electoral Commission (AEC).
The Join The Conversation website was registered by Ms Lloyd and purported to be a platform to connect voters to their local minor party candidates.
However, it only contained links to anti-vaccine mandate "freedom candidates" from One Nation, the United Australia Party, the Great Australian Party and one independent.
The website has since been updated to include candidates from the Informed Medical Options Party and a candidate for the Liberal Democrats.
The AEC this week said it was investigating the Join the Conversation site, which included a page without authorisation that solicited donations to pay for political advertising material to promote minor party candidates.
After questions from the ABC, the donations page was removed.
One Nation issued a statement on Friday afternoon saying it had "discontinued its association" with Ms Lloyd.
"Her unwillingness to work with and follow direction from One Nation’s national executive as part of this team has led to the regrettable, but unanimous, decision to disendorse Ms Lloyd as the party’s candidate for Brisbane," the statement said.
"One Nation wishes Ms Lloyd all the best with her future endeavours."
Earlier on Friday, Ms Lloyd took to her Facebook page to say her candidacy had been revoked after what she described as an inaccurate mainstream media "hit piece".
"In the story, it is claimed I am under investigation for potential electoral fraud by the AEC," she told her followers in a live video.
"I have been deleted from all One Nation channels. It looks like I am being disendorsed.
"I have done nothing wrong. The AEC is not investigating me and I have been deleted for standing up for myself."
Ms Lloyd's name and details have also been removed from the One Nation website page that lists candidates in the upcoming election.
Brisbane businessman Peter Cutforth, who says he is not aligned with any political party, has claimed he is responsible for running the Join the Conversation website.
In a curious twist, he said "UAP officials" had "cleared the site a few weeks ago".
But, he explained, those officials had since "advised Ms Lloyd that the donate button may not be compliant with new AEC requirements, and so, of course, it was removed".
It is unclear why the United Australia Party would be clearing an independent website registered by a One Nation candidate.
"In any case, I am satisfied that Ms Lloyd provides transparency regarding financial transactions relating to the site, and operates with integrity," Mr Cutforth told the ABC.
Ms Lloyd and the UAP did not respond to requests for comment before publication.
An AEC spokesman confirmed to the ABC that investigations into the Join the Conversation site were ongoing.
