Queensland senator-elect Pauline Hanson has fought back tears recounting her 2003 jailing over quashed political corruption charges, blaming Tony Abbott and John Howard for a "political witch-hunt" against her.

Following her resurgence at the July 2 election, a new SBS documentary about the 1990s rise and fall of One Nation has been brought forward for broadcast later this month.

Ms Hanson promises her maiden speech in the Senate will be just as controversial as her explosive 1996 parliamentary debut, in which she said Australia was at risk of being swamped by Asians.

The film, directed Anna Broinowski, explores One Nation's impact on multiculturalism in Australia and includes interviews with Mr Howard, incoming Labor federal MP Linda Burney and Indigenous leader and academic Marcia Langton.
