Outspoken Tasmanian Jacqui Lambie has her fingers crossed for a return to the senate because she has "unfinished business".
The senate candidate cast her vote early on Saturday morning with little fanfare at the Burnie Council Chambers.
Six senate spots are up for grabs in Tasmania.
"I think for me it's unfinished business," Ms Lambie told Network Ten on Saturday night.
Ms Lambie was elected to the senate as part of the Palmer United Party in 2014 but quit to become an independent.
She was then forced to resign after being caught up in the dual citizenship saga.
"I've still got things that were given to Tasmania that have not been passed along, so I want to make sure that any deals that are done are passed along to Tasmania," she said of her campaign.
Labor's Lisa Singh is in the mix, along with sitting senators Nick McKim from the Greens and the Nationals' Steve Martin.
"All I can do is cross my fingers and wait until the end of the day," Ms Lambie said.
"It's anyone's game. It'll depend where the preferences flow obviously."
Ms Lambie has covered plenty off territory across the Apple Isle in her campaign van but wouldn't detail a Plan B if her 2019 tilt fell short.
"People have been asking me that question the last 24 hours. I'm beginning to think they're trying to tell me something," she said.
"I haven't even thought about that. I do know the week after the election I'll take down the signs."
