Senator Singh now lies behind Labor left's Anne Urquhart, the right's Senator Helen Polley and Australian Manufacturing Workers Union representative John Short after Friday night's controversial ballot.

Figures obtained by The Examiner from a Labor insider show Senator Singh placed third in rank and file with 110 primary votes behind Senator Polley's 123 and Senator Urquhart's 221.

Although Mr Short received only 74 primary votes in rank and file, the state conference tally gave him 31 votes to Senator Singh's 16.

The outcome left Senator Singh and Mr Short tied with a 14 per cent total count.

According to the figures, it was the distribution of Senator Urquhart's vote that pushed Senator Singh to the unwinnable fourth ticket position.

The cut-up shows a windfall for Mr Short, providing him with 184 rank and file votes against Senator Singh's 36.

A further 104 conference votes were added to Mr Short's total, with only two distributed to the Labor parliamentary secretary for Environment, Climate Change and Water.

Senator Singh is an unaligned party member and on Saturday said she was disappointed with the outcome of the vote.

"I knew it was going to be tough when the factions had done a deal," she said.

"Obviously I'd love to continue in the senate, but I do still have two years left in my term and will continue to represent Tasmania and I still have a lot to do as part of the shadow ministry.

"I want to thank the party members who supported me and continue to do so."

Polling expert Kevin Bonham said he was not surprised by Senator Polley's standing on the state ticket.

"Although she had a rather controversial mid-term, factional links appear to make her a protected species," Mr Bonham said, citing past bullying allegations and Senator Polley's controversial flight expenses between Launceston and Hobart.

Tasmanian Labor state secretary John Dowling said Mr Short's position in the statewide ballot reflected hard work within the manufacturing industry.
