Jacqui Lambie of the Palmer United Party has stormed home to win Tasmania's sixth and final Senate seat following a cliffhanger count decided by preferences.
The Burnie based candidate was a rank outsider on election day, with other parties predicting the party's vote to be around two per cent.
The party formed by mining magnate Clive Palmer polled 6.6 per cent of the vote, just under half a quota.
The result was tough on Liberal candidate Sally Chandler, who was ahead on votes above the line but was overtaken on preferences.
The race was the closest count in years, with electoral analysts unable to predict a winner as late as yesterday.
Joining them in the Senate will be Liberals Richard Colbeck and David Bushby, and Labor's Carol Brown and Catryna Bilyk.
Green Peter Whish-Wilson was also elected after Labor preferences topped up the Green vote, which was just below a quota.
The result means the end of a second parliamentary career for Labor's Lin Thorp, who was appointed to the Senate to fill a vacancy left by Nick Sherry.
Sex Party candidate Robbie Swan was also in the mix but could not muster enough below the line preferences to overtake his rivals.
