Pauline Hanson One Nation candidate Rodney Culleton has won a West Australian Senate seat but might never get to take it up due to criminal charges and two possible convictions he is facing.
The 52-year-old anti-bank farmer from WA's Wheatbelt won the state's 11th Senate spot, joining five Liberals, four Labor and two Greens.
Mr Culleton is appealing his conviction in NSW earlier this year for stealing a tow truck key from a driver who was trying to repossess one of his company cars.
He is also awaiting trial in WA later this month - the week before parliament begins - after he was arrested and charged for allegedly stealing a car being used by receivers from RSM Bird Cameron as they began foreclosure proceedings at a friend's farm.
The charges are serious enough to potentially deem him ineligible to be a senator.
If the Court of Disputed Returns did bar him, the other two One Nation candidates in line are Mr Culleton's wife Ioanna and brother-in-law Peter Georgiou.
Nationals Senate candidate Kado Muir came 13th and was the highest placed loser while Greens stalwart Rachel Siewert won the lucky last 12th seat in WA.
Greens co-deputy leader Scott Ludlam scored third place, having almost lost his seat in 2013 during a chaotic WA count which resulted in the state having to rerun its Senate election.
Ms Siewert and Mr Ludlam highlighted Aboriginal and Torres Strait Islander issues, including the royal commission into juvenile justice in the NT, and social justice changes as priorities on Monday.
WA's list was topped by Finance Minister Mathias Cormann and Labor's Sue Lines.
Employment Minister Michaelia Cash was fourth.
Indigenous leader Pat Dodson won the seventh slot for Labor, while the opposition's Louise Pratt was returned in 10th place after losing her seat in 2013.
