Former Liberal Sue Hickey says the government needs to show Tasmanians what they have actually delivered for them over the past term.
Ms Hickey was a member of the government until Sunday when she received confirmation she would not be re-endorsed to run in a state election with the party.
She then announced she would run as an independent which meant she was automatically dismissed from the party.

Ms Hickey said she and fellow independent Madeleine Ogilvie had guaranteed supply and confidence to the government in writing.
She said therefore, she could not be blamed for triggering the early election.
Ms Hickey said the Premier had called the election because he was riding high in the polls and governments in other Australian jurisdictions had been re-elected due to their strong efforts in fighting the coronavirus pandemic.
"Every leader of the country that has led their state through COVID has done well," she said.
"But that doesn't give him a free kick ... he has to show us what he's actually delivered.
"We've had heaps and heaps of announcements - there's always an announcement and there's always a new thought - but where are the things on the ground."
Ms Hickey said majority governments were dangerous and toxic.
"They bully internally, they push out some dud policy and then they try to get it through the house," she said.
"They become lazy governments."
