OPPOSITION Leader Will Hodgman has returned from Canberra with a commitment from the federal government to provide "certainty and security" for the Tamar Valley pulp mill.
Mr Hodgman met Prime Minister Tony Abbott and senior ministers this week to pursue federal support for the project, but shed no light on what could be on offer for prospective investors.
"I'm not going to be able to comment on specific propositions, I will say that the shared objective of seeing this project become a reality is significant," Mr Hodgman said.
Receivers for failed timber company Gunns have put the land and permits for its controversial pulp mill on the market.
Expressions of interest close at the end of this month.
While Labor has also strongly supported the pulp mill, the Greens slammed Mr Hodgman's Canberra mission.
Greens forestry spokesman Kim Booth said Mr Hodgman had clearly returned empty-handed from the taxpayer-funded junket.
"Fortunately no one in Canberra could see Mr Hodgman's pulp mill mirage and they sent him packing," Mr Booth said.
