More than 100 jobs are expected from new private sector investment in visitor infrastructure near the Cradle Mountain national park.
The state government is offering leasehold or freehold options for development of land within the Cradle Mountain "gateway precinct".
Proposals might include a hotel or hotels, a helipad, eateries and/or retail outlets.
Treasurer Peter Gutwein said the gateway precinct was outside the national park and world heritage area and presented "an outstanding opportunity to provide a unique visitor experience through partnership with private investment".
"Cradle Mountain is one of Tasmania's iconic visitor destinations and a major visitor drawcard, expected to attract up to 339,000 visitors by 2020."
He said that was why the state government was committed to its Cradle Mountain Master Plan and had made "an unprecedented investment of $56.8 million for the development of essential infrastructure at the new visitor centre and Dove Lake".
Our plan will ensure the visitor experience at Cradle Mountain matches the spectacular beauty of the area ...Peter Gutwein
"It is vital that we get this once in a generation development right.
"This is a strategic project and providing the option of either leasehold or freehold will ensure we attract the right proponent, who will invest in the community, creating local jobs while ensuring the ongoing protection of the environmental and cultural values of this magnificent region.
"Fit-out of the new cafe and negotiations for a short-term lease with a suitable operator are already under way and the government is also progressing discussions for a staff accommodation development.
"Our plan will ensure the visitor experience at Cradle Mountain matches the spectacular beauty of the area, as well as increasing investment in the Cradle Coast region, boosting the visitor economy and creating jobs."
Submissions to the government's agent, Colliers International, would close on December 12.
Late last year, Tasmanian construction company Fairbrother won a $12 million contract for a new Cradle Mountain visitor centre and gateway precinct projects.
They would include visitor services and tourist operator buildings, a cafe and a car park extension.
A development application for a new Dove Lake viewing shelter was approved by the Kentish Council in August.
