The crossbencher, who recently brokered a deal to wipe the state's historic public housing debt owed to Canberra, has turned her attention to securing tertiary education funding.

"When it comes to infrastructure, TAFEs are pretty depleted," Ms Lambie told ABC Radio on Tuesday.

"For me it's really important to make sure these trade schools stay around."

Ms Lambie is after between $50 million and $100 million to upgrade ageing TAFE facilities in her home state.

She wants the money to come from the federal government's planned $4 billion emergency response fund, which is being drawn from a pool of money for education infrastructure.

"While they want to transfer all that money over there, while that opportunity is there ... I could grab some money for Tasmania and get our TAFEs up and running," Ms Lambie said.

The senator, however, said she would not use her likely deciding vote on the federal government's medical evacuation legislation as a bargaining chip.

"I don't think Tasmanians would be comfortable, like I'm not, doing deals over humanity," she said.

The senator earlier this year convinced Canberra to wipe Tasmania's $150 million housing debt in return for her support of the Morrison government's tax plan.

Ms Lambie lashed the state Liberal government for not doing enough to support TAFE but said she had been speaking with them about the issue for several weeks.

State Education Minister Jeremy Rockliff said the government would welcome any additional support Ms Lambie can secure.

TasTAFE on Tuesday announced it will shut its Launceston CBD campus at the end of the year so it can upgrade another campus on the fringe of the city.

The state Labor opposition claims the closure of the campus highlights a lack of investment in the vocational education sector.
