The battle for Braddon in Tasmania has gathered stream, with the federal government chipping in $30 million for a cableway at Cradle Mountain in the state's northwest.
Prime Minister Malcolm Turnbull made the announcement on Wednesday alongside Premier Will Hodgman at the mountain - one of the state's tourist hotspots.
"It's been under discussion for quite some time now, but obviously, the timing is very appropriate given that at long last we're actually having a by-election in Braddon," Mr Turnbull told reporters.
Voters in the huge electorate will have to return to the polls after Labor MP Justine Keay last week quit parliament after becoming snared in the dual citizenship saga.
But Mr Turnbull has denied the funding is an outright vote grab to get Liberal Brett Whiteley re-elected.
"This is a cableway to get people up here, to deliver 60,000 more visitors and many more jobs in Tasmania," he said.
The cableway is part of a $160 million plan to upgrade facilities at Cradle Mountain, including extra accommodation and a new visitor centre.
Mr Hodgman said the cableway would be built as soon as possible.
It is expected to create 150 jobs during construction and 50 ongoing positions.
"This is a World Heritage area. It is very sensitive. It has to go through proper planning processes and approval, including with the Commonwealth," Mr Hodgman said.
"Quite likely there'll be some who will want to see Tasmania stand still.
"But we are prepared to embrace the fact that our wilderness is not only important to us, but to the people who come here.
"We've been to an election on this. Tasmanians know we're a government that supports development, including in and around our wilderness areas."
