The major parties are out of step with Tasmanian voters in their unwavering support for a $945 million stadium in a deal for an AFL team, a pre-election poll suggests.

With a snap election in weeks, Tasmanian voters were surveyed on their attitude to the deal with the AFL to build a roofed stadium at Macquarie Point.

The Hobart stadium is a condition of the licence for the Devils’ inclusion in the AFL competition in 2028.

The online poll of 842 voters, conducted by YouGov on behalf of progressive think tank the Australia Institute from July 12-16, indicates most Tasmanians believe the stadium deal is unfair.

More than two out of three (69 per cent) support Tasmanian parliament renegotiating with the AFL to avoid constructing a new stadium.
