Ousted One Nation senator Malcolm Roberts is set to stand for the party in the Queensland election.
Mr Roberts was on Friday one of five federal politicians the High Court disqualified from sitting in federal parliament due to dual citizenship issues.
Within hours of that ruling, One Nation leader Pauline Hanson announced Mr Roberts will stand in the seat of Ipswich at the upcoming Queensland election, which could be called as soon as Sunday.
Describing Mr Roberts as a "great man", an emotional Ms Hanson said she was confident the people of Ipswich - an area she sees as the "heart of One Nation" - will embrace the ex-senator.

"Federal parliament may have lost Malcolm Roberts but Queensland has not lost Malcolm Roberts," Ms Hanson told reporters.
"The Queensland state leader Steve Dickson is over the moon. He's so delighted about having an experienced candidate like Malcolm Roberts to stand for the seat of Ipswich."
Labor's Jennifer Howard currently holds Ipswich with a 16 per cent margin under new electoral boundaries.
The LNP held the seat from 2012 to 2015 but traditionally Ipswich has been a safe seat for Labor, which has held it since the 1980s.
However, Ms Hanson's old federal seat of Oxley lies in the electorate and One Nation nearly won the state seat in 1998.
Former Queensland Labor premier Peter Beattie said Mr Roberts running in the seat would have an unpredictable effect on politics in the state.
"Him running, because of his standing, because he's known, will really shake up Queensland politics," Mr Beattie told Sky News.
"It's not good news for the Labor party, him running in a state seat."
