He said Treasury had advised Forestry Tasmania to enter a profit-sharing deal with Aprin, the company buying the mill.

The Greens and the Liberals asked if that meant Tasmanian taxpayers would then be liable for potential losses.

Premier Lara Giddings said she did not have the necessary detail on possible losses.

"There's a lot of information and complexities around these issues which I don't feel I'm able to explain and stand with you here today around these things," she said.

"A lot of it is also commercial in-confidence."

Ms Giddings said Forestry Tasmania's business was finding a market for its wood products.

She said without the Triabunna mill operating, that job became harder.

Economic Development Minister David O'Byrne said the Tasmanian Development Board's potential loan to Aprin to help buy the Triabunna mill had not yet been approved.

"Once the board concludes its discussions we will be able, to the point that it does not impact on the commercial activity, to release the details of the deliberations of the board and whether it is approved or not," he said.

Greens economic development spokesman Tim Morris said the Greens still believed the loan should not be provided to Aprin. Mr Morris also said details of any loan and profit-sharing arrangements should be publicly disclosed.

Opposition forestry spokesman Peter Gutwein said transparency was needed. "While there is no bigger supporter of the forestry industry in Tasmania than the Liberals, what we do need is some openness and transparency regarding these deals that the Green- Labor government have been negotiating on behalf of the taxpayer, and with taxpayers' money, behind closed doors," he said.
