The Tasmanian Government will be under pressure to reveal more details about the potential sale of public assets when Parliament resumes today.

The historic Treasury building, the University of Tasmania's Arts School and the public offices in Launceston are among the state-owned buildings earmarked for sale.

It was under questioning in Parliament earlier this month that details of the potential property deals, which also involve TasTAFE's Hobart campus, were revealed.

Labor's treasury spokesman Scott Bacon said he suspects there could be discussions between the Government and developers about state-owned buildings that have not been made public yet.

"I think there are a range of different assets the Government is looking to privatise that they haven't been upfront with the Tasmanian people about," he said.

He did not name which other buildings could be under consideration for sale.

"It's very difficult for us to say but I think it's time the Government answered those questions," Mr Bacon said.

Greens Leader Cassy O'Connor is calling for answers about the coordinator-general's role in the process.

"Who is it answerable to? What public assets are in play here?" she said.

"The door to the Minister's office and the office of the coordinator-general is wide open and the red carpet's being rolled out to developers looking at public assets."

In Parliament, State Growth Minister Matthew Groom initially denied there was a specific proposal to transfer ownership of the TasTAFE Hobart campus in Campbell Street.

He later corrected the record and tabled a memorandum of understanding with the University of Tasmania, signed in September, to explore a property swap which could clear the way for a hotel development at the Arts School in Hunter Street.

"We're very concerned that the information that's been drawn out of the Liberals in Parliament is just the tip of the iceberg," Ms O'Connor said.

Treasurer Peter Gutwein said he was not aware of any more properties being considered for sale.

"Isn't it a good thing that there is interest in Tasmania at the moment? Isn't it great that we've got investors out there that want to come to Tasmania, that want to invest in Tasmania and want to have a conversation with Government?" he said.

Sex offender treatment legislation to be tabled

Meanwhile, sex offenders who refuse treatment while in prison will not be released early, under legislation to be tabled today.

The corrections amendment bill will require the Parole Board to consider whether the prisoner has undergone appropriate treatment designed to address the underlying causes of their behaviour when assessing an application for parole.

It also directs the head of the prisons not to grant remission of a sentence to a sex offender if the prisoner has chosen not to participate in treatment, or if the prisoner's participation was unsatisfactory.

The Government is seeking advice from the Sentencing Advisory Council on implementing its election promise to make treatment for sex offenders mandatory.
