Labor senator Lisa Singh has taken a swipe at the ALP's factional bosses after being relegated to an unwinnable sixth spot on the party's Tasmanian Senate ticket.

Senator Singh suggested the decision to relegate her to last spot was a backroom deal made by a handful of powerbrokers.

"All political parties have factions. As I've said in the past, factions are not a bad thing," she said.

"What's not healthy in any political party is when power kind of comes down to the hands of only a few, and I think that's a further discussion to be had about party reform.

"I'm not a fan of backroom deals whatever the party, so I've always been someone that's supported good processes.

"I still think Labor has those good processes but there's always room for improvement."

Senator Anne Urquhart has secured the number one position in Tasmania, followed by Helen Polley, Carol Brown and Catryna Bilyk.

Manufacturing Workers Union secretary, John Short is in fifth place.

Labor powerbroker Don Farrell is poised to return to Federal Parliament, after securing second place on the South Australian ticket behind Leader of the Opposition in the Senate Penny Wong.

In New South Wales, Senator Sam Dastyari tops the Labor ticket, followed by former ALP national president Jennifer McAllister, senators Deb O'Neill and Doug Cameron.

Former industry minister Kim Carr is number one on the Senate ticket in Victoria, followed by Stephen Conroy, Jacinta Collins and Gavin Marshall.

Two people not currently in Parliament top the Queensland Senate ticket for Labor — Murray Watt, who replaces the outgoing senator Jan McLucas, and Anthony Chisholm, who will take over from Joe Ludwig.

In Western Australia, senators Sue Lines and Glenn Sterle are one and two on the Labor ticket, followed by Indigenous leader Pat Dodson, who replaced Joe Bullock earlier this year following his resignation.

Former Labor senator Louise Pratt, who lost her position following the WA Senate recount of 2014, is in a winnable fourth position.

Senators Katy Gallagher and Nova Peris are top of their respective tickets for the ACT and the Northern Territory.
