The Prime Minister endured near freezing conditions at Cradle Mountain to officially commit $30 million towards a cable way attraction.
The funding's timing is ahead of a by-election in the north-west seat of Braddon.
Malcolm Turnbull said the development was a huge deal for the region and the state more broadly.
"This is going to add 150 jobs in construction and there's going to be 50 additional ongoing jobs, 60,000 more visitors," he said.
"It's a low impact environmentally friendly cable way that is going to get cars off the road."
The $30 million dollars was announced in a press release from Tasmania's newest senator, Independent Steve Martin.
"It's been my honour and privilege to work with the Prime Minister and Senator [Mathias] Cormann in securing this $30 million for this project," he said.
"It certainly will highlight what Cradle Mountain is and attract more international visitors."
But the Prime Minister flatly rejected suggestions he was courting Mr Martin as a possible addition to the Liberal party.
He was asked by Brian Carlton on Tasmania Talks if he had made an offer to Senator Martin to join his Government.
"[Laughing] No, no we haven't. Well I certainly haven't done that," he said.
"I'm not aware of any such offer but I can say to you though, that we work very closely with the cross bench.
"We work respectfully with the cross bench and we seek their support."
