Labor leader Dean Winter has unveiled his proposed ministry as the party prepares to try and topple the Liberal government in parliament next week.
A no-confidence motion against Premier Jeremy Rockliff is expected to be tabled when parliament returns next Tuesday.
Labor is banking on crossbench support to oust the government and return to office for the first time since 2014.
In an unprecedented move, Winter has looked outside the party for his treasurer, naming independent Murchison MLC Ruth Forrest to the role.
He is also proposing a new “Special Minister of State” position, to be filled by Ella Haddad, tasked with managing minority government and dealing with an expanded crossbench.

That role does not exist under the current government, though Premier Jeremy Rockliff has stepped back from his ministries to focus on the state and crossbench relations.
Winter’s frontbench line-up would see several MPs promoted to senior roles for the first time. Anita Dow would become deputy premier, also taking on infrastructure and transport.
Shane Broad would oversee resources, planning, building and consumer affairs, while Janie Finlay would manage environment and primary industries, along with climate change, aquaculture and renewable energy.
Josh Willie would serve as leader of government business and hold the education, early years, TAFE and skills training, children and young people, and multicultural affairs portfolios.
Meg Brown would take on housing, community services, prevention of family and sexual violence and heritage and arts.
Jen Butler would be responsible for police, fire and emergency services, corrections and rehabilitation, veterans’ affairs and small business.
Luke Edmunds would manage stadiums and sport, racing and hospitality, while Sarah Lovell would take on health and ageing, disability and women’s portfolios.
Craig Farrell would serve as Leader of the Government in the Legislative Council.
Winter himself would be premier while picking up the invest Tasmania, tourism and events portfolios.
