Ms Hanson has been held responsible for politicising immigration policy
Australian former anti-immigration politician Pauline Hanson is selling up and heading to Britain, according to an interview with an Australian magazine.
She told Women's Day that Australia was no longer a land of opportunity and she had "had enough" of living there.
Ms Hanson built a career on claims that Australia was being "swamped by Asians"
She was jailed briefly for fraud before the conviction was quashed. Her efforts to stage a political comeback in recent years have failed.
"I'm going to be away indefinitely. It's pretty much goodbye forever," said Ms Hanson, 56.
"I've really had enough. I want peace in my life. I want contentment, and that's what I'm aiming for."
She told the magazine she would "never be given a chance to re-enter parliament" and wanted to "get out there" while she still had her health.
"Sadly, the land of opportunity is no more applicable," she said, blaming high taxes, over-regulation and a "lack of true representation".
Ms Hanson's father was born in England before emigrating to Australia, meaning she has the right to live in the UK.
Opposition Leader Tony Abbott said he was disappointed by Ms Hanson's decision but that it was her decision to make.
"There was a time when she articulated a cry of rage from a section of the Australian population," the Herald Sun newspaper quoted Mr Abbott as saying.
"But that time has passed and she's now chosen to go in different directions and that's her right."
Ms Hanson was popular with some Australians in the 1990s with her anti-immigration and trade protection policies, before losing her seat in 1998.
At its peak, her One Nation party attracted a million votes.
In 2007, she ran unsuccessfully for a national Senate seat, switching her target from Asians to Islam and calling for an end to immigration by Muslims to protect "Australian culture".
Last year, Hanson blamed her failure in the Queensland state election on the publication of raunchy photos purportedly taken by an ex-boyfriend. The pictures turned out not to be of her.
