Pauline Hanson's chances of getting two of her One Nation colleagues over the line in the Senate have lifted with lucky ballot paper draws in Queensland and Western Australia.
One Nation drew second spot on the Queensland Senate ballot paper and first on the WA paper, in a process conducted by the Australian Electoral Commission on Wednesday.
Senator Hanson is aiming to get ex-senator Malcolm Roberts up in Queensland and return Senator Peter Georgiou in WA.
The right-wing Rise Up Australia Party claimed first spot in Queensland with Clive Palmer's United Australia Party third.
Home Affairs Minister Peter Dutton drew second place on the ballot paper in his Brisbane seat of Dickson, just ahead of Labor rival Ali France and behind the Greens' Benedict Coyne, whose preferences will be crucial to a potential upset.
Mr Dutton did not attend the draw.
Former prime minister Tony Abbott placed ahead of main rival independent Zali Steggall in his Sydney seat of Warringah.
Both were on hand to watch the draw in a crowded office in Manly.
Ms Steggall placed eighth, while the former prime minister was drawn in sixth spot.
"The electors are pretty smart and they'll navigate the ballot paper pretty well, I'm sure," Mr Abbott told reporters.
Ms Steggall compared the ballot to her time as an Olympic skier.
"I've been at the draw before in an Olympic Games race where you're really hoping to get that number one because you're going to have a clean course. This is about people choosing and focusing on policies," she said.
Labor's Libby Coker claimed second spot for the marginal Victorian seat of Corangamite, ahead of sitting Liberal MP Sarah Henderson in sixth place.
Liberal candidate for the South Australian seat of Mayo, Georgina Downer, scored top spot ahead of sitting Centre Alliance candidate Rebekha Sharkie in sixth and last place.
Election analyst Kevin Bonham said a higher place on a ballot paper represented about a 0.5 point advantage for a major party candidate.
And there was strong evidence confusingly-named parties received an advantage of about two points if they drew to the left of a similarly named party.
