Pauline Hanson says several failed attempts at reviving her political career have not deterred her from standing at the next Queensland election.
Ms Hanson, 60, has returned to lead the right-wing One Nation party she founded 17 years ago.
The polarising figure will stand in Lockyer, a farming electorate west of Brisbane, despite living just outside the boundary in neighbouring Beaudesert.
"If it's any concern where I put my head down at night, that's a real worry," Ms Hanson told reporters.
LNP MP Ian Rickuss has held Lockyer since 2004.
Ms Hanson said she had family connections in the electorate and would campaign on issues affecting Lockyer, including a lack of support for farmers and opposition to coal seam gas.
The former federal MP stood in Beaudesert in 2009 but her bid failed, just like similar attempts at the NSW upper house and Senate.
When asked why she kept trying, Ms Hanson said it was because she was an "Aussie fighter".
"I don't consider myself a failure. A failure is someone who doesn't win the first time and walks away," she said.
"I've kept going because I believe in what I'm doing. I'm passionate about my country, I'm passionate about these views."
Ms Hanson, who made headlines for her controversial views on immigration, said she would not campaign on the topic because it was a federal issue.
But she did call into question Australia's refugee process after it was revealed the Sydney siege gunman came to Australia as an asylum seeker from Iran.
She also reiterated her long-held view that multiculturalism "hasn't been working" in Australia.
Ms Hanson served as federal MP for Oxley in 1996-98.
