Outgoing Premier Will Hodgman says it would be inappropriate for him to vote on the new Liberal leader, given he won't be a part of the team.
It means 14 members are expected to decide on who will take the state's top job, when the Parliamentary Liberal Party meets on Monday to select either Peter Gutwein or Michael Ferguson, with a tie now a real possibility.
“I believe our entire team has great depth, great capacity, great passion and commitment and will move forward very swiftly and get on with the job that we were elected to do and keep delivering for our state,’’ Mr Hodgman said at what is likely to be his final press conference as Tasmanian Premier and Tourism Minister: Pennicott Wilderness Journeys launching their recently acquired Wineglass Bay Cruises.
It's shaping up as a clash between the moderate and conservative wings of the Liberal Party.
Meanwhile, the state's business lobby is having an each-way bet on the candidates.
Bookies have Mr Gutwein as the favourite at this stage, with the state to get its first northern Premier in decades.
The Tasmanian Chamber of Commerce and Industry says either will perform well as Premier number 46.
Elsewhere, the Opposition's continuing to make hay of the unusual delay in selecting Will Hodgman's replacement, warning the government to walk away from plans for a prison at Westbury.
Lyons MP Jen Butler says the two aspirant Premiers need to make their positions on the controversial project clear.
