Noel Jackman, who worked in the forest industry for decades, said taxpayer money should have gone to help native forest contractors - not those who had already moved into plantation timbers.

The industry restructure has almost ensured the end of the vast majority of native forest logging in preference to plantations.

Mr Jackman said some contractors who sold their contract had got an exit package - but those they sold it to were rejected because they were ineligible.

"There are good people missing out," he said.

Mr Jackman said he was speaking out on behalf of those who couldn't for fear of losing their work.

Bass Greens MHA Kim Booth said the exit package rollout should be stalled until a probity audit was completed.

He said his office had been contacted on a "daily basis" over the past few weeks by angry forest contractors who all raised the same issues.

"This exit package was badly needed by the industry, but if the process has been rorted in the manner that is being suggested to me by multiple contractors, then it is imperative that (federal Forestry Minister Joe) Ludwig immediately launches a probity audit, answers the questions that the contractors are raising and comes clean about issues related to the selection process used to determine eligibility," Mr Booth said.

Senator Ludwig has previously denied he had been "secretive" in relation to determining which Tasmanian forest contractors were successful in obtaining funding to help them exit the industry.

Of the 83 applicants, 30 were successful and the Department of Agriculture, Fisheries and Forestry has been negotiating funding deeds with the successful applicants.

A spokeswoman for Mr Ludwig said the federal government publicly released the guidelines for the exit assistance package.

Offers were made to 30 successful applicants before Christmas and the department is negotiating funding deeds.

She said that offers would be finalised in the coming weeks and the details would be published online.
