Former One Nation senator Malcolm Roberts will make a bid to return to federal parliament at the next election, leading the party's Queensland Senate ticket.
Party leader Pauline Hanson announced One Nation would stand candidates in all lower house seats in Queensland and in all Senate races at the federal election, due later this year or early 2019.
Mr Roberts was forced out of the Senate last year after the High Court ruled he was a British dual citizen and thus ineligible to sit in parliament.
He unsuccessfully ran in November's Queensland state election.
"Malcolm Roberts has got the reputation as a powerhouse, the empirical science man, and he's really taken it up to members of parliament," Senator Hanson told reporters on Tuesday.
Steve Dickson, who defected from the Liberals to One Nation in January 2017 and lost his state parliament seat in November, will be second on the Queensland ticket despite being the party's state leader.
