The Australian Electoral Commission (AEC) confirmed the positions on Tuesday.

The other five places will be filled by Labor’s Carol Brown and Richard Dowling, Liberal’s Claire Chandler and Richard Colbeck, and Nick McKim from the Greens.

In order of election, The Jacqui Lambie Network came in fifth followed by Colbeck.

The formal declaration of the poll for the Tasmanian Senate is set for Thursday.

Lee Hanson celebrated her mother Pauline’s birthday before acknowledging the loss.

“Unfortunately, I did not pick up a seat, falling just short,” she said on Facebook.

“While I personally had a very short campaign of approximately one month, we did exceptionally well, raising the vote here in Tasmania.

“It is however just the beginning. I truly care about this country, the beautiful state of Tasmania and our people. I will continue to advocate for what I believe is best for us, championing common sense and holding politicians to account.”

Meanwhile, South Australia now has a new young female Senator.

Labor’s Charlotte Walker, 21, secured the state’s third spot in the Senate.

In the lower chamber, two seats are undergoing recounts amid fierce contests.

Election officials in the north Sydney seat of Bradfield are undertaking a full recount after just eight votes separated Liberal candidate Gisele Kapterian from independent challenger Nicolette Boele.

Meanwhile, a partial recount is underway in the inner-Melbourne seat of Goldstein, where independent Zoe Daniel was fending off Liberal candidate Tim Wilson.

The full distribution put Wilson ahead of the incumbent by 260 votes.

The Bradfield recount could take up to two weeks, while the tally in Goldstein is expected to take four days and will begin on Wednesday.
