Ms Whelan was disendorsed by the Liberals at the May election.

The 92-page review made 60 findings and 26 recommendations.

It acknowledged swings against Labor in Braddon of 4.82 per cent and Bass 5.83 per cent.

"In Lyons, the Liberal Party was forced to disendorse its candidate following inflammatory social media comments," it said.

"There is no reason to assume a similar swing would not have delivered a Liberal victory in Lyons had this controversy not derailed the Liberal campaign."

Labor Lyons MHR Brian Mitchell said the review was an "internal matter" and he was focused on the electorate.

"The economy is on the skids and everything is going up in price - that's what is important for people," he said.

Labor senator Helen Polley said the review highlighted the need for Labor to re-engage with the regions and be more inclusive.

"The Labor base has to be much broader and more inclusive," Senator Polley said.

"The review showed that many Christians did not feel connected to us. We have not been inclusive enough for a long time and people want to know what the jobs of the future are going to be."

Senator Polley said the review was a "valid" document the party could work with.

The review said the Labor-Green government from 2010-2014 "remains a sore point for many voters in northern Tasmania, who view the Greens as implacably hostile to their interests, values and livelihoods".

"For a Labor candidate in northern Tasmania, any perception a vote for Labor could lead to more power and influence for the Greens is very damaging. "

The review says the Liberals' campaign in the North wrongly "misrepresented" Labor's support for an AFL team and saw tourism support as "Hobart-centric".

"Labor's campaign did not overcome the resentment this generated in the North," it said.

The review says Pauline Hanson's One Nation Party polled well in Braddon.

"One Nation's decision to preference the Coalition in the seats of Longman and Braddon probably cost Labor those two seats," it said.

Braddon independent Craig Garland won more than 10 per cent of the vote and despite a three per cent fall in the primary vote, Labor's two-party preferred vote was up.

The review said former Greens leader and senator Dr Bob Brown's Adani mine convoy highlighted "Labor's ambiguous position on the Adani proposal and enabled the Coalition repeatedly to reaffirm its unequivocal support for the mine".
