Tasmania's Labor opposition says it wants to see a ban on "pork barrelling", to ensure community grants are funded at arm's length from politicians, but the premier says he's "never heard a bigger load of bull crap".

Pork barrelling is the practice of allocating taxpayer funds and resources to targeted electors for political gain — something both major parties were accused of last state election.

Labor leader Dean Winter said if elected to government, he would ensure that every government grant went through an independent process to assess each proposal on its merits.

"And that's not what's been happening.

"We don't believe that you should need to know a Liberal Party member in order for your sports club to get funding."

The Liberal Tasmanian government handed down its state budget on Thursday, which projects debt levels will rise to $8.5 billion in four years' time.

Mr Winter said the budget lists 480 election commitments totalling nearly $1.3 billion.

"Individually, nearly all of them have some merit," he said.

'Never heard a bigger load of bull crap': Premier

Premier Jeremy Rockliff said Labor's proposal was "breathtaking in its hypocrisy".

"I've never heard a bigger load of bull crap coming from the Labor Party," Mr Rockliff said.

"Labor out-spent us at three to one when it comes to their commitments that they made to the Tasmanian people, spending like drunken sailors.

The government's Leader of the House, Eric Abetz, said:

"It's up to Tasmanian voters to decide how their money is spent, not unelected government employees."

Mr Rockliff said Labor had promised $4 billion in funding commitments during the election campaign.

"Dean Winter couldn't wait to get on Facebook and spend taxpayer money with no thought, [with] secret letters to constituents and community organisations," he said.

In March, the state government accused Labor of making politically motivated funding promises, citing a "secret letter" written by then-leader Rebecca White to Derwent Valley Mayor Michelle Dracoulis promising $400,000 for community facility upgrades.

At the time, Labor said it had spoken to all councils asking for their priority projects and these were not kept secret.

JLN's Jenner says 'verbal agreement' stands

The remaining Jacqui Lambie Network MP in the parliament, Andrew Jenner, released a statement on Monday stating he would no longer enter into a new confidence and supply agreement with the government.

Mr Jenner and his two former colleagues, Miriam Beswick and Rebekah Pentland, signed a deal with the premier in April, but when Ms Beswick and Ms Pentland were kicked out of the JLN and went to the crossbench, they negotiated a new deal.

Mr Jenner said he would also re-negotiate his deal but on Monday, he changed his mind, and said he was unable to sign a new agreement because "the premier refused to end the Liberal Party's use of public funds to pay for what the Integrity Commission has labelled electoral bribery".

"If something needs funding then it should get it, but why is it always in the few weeks before an election?" Mr Jenner said.

Later at a press conference Mr Jenner clarified that a verbal agreement with the government for confidence and supply would still stand.

Even without Mr Jenner's vote, the government still has 18 supporters on the floor of parliament, including four independents.

The Tasmanian Greens have put their support behind Labor's promise, but with another state election not for another three years, said the policy should be taken to parliament.

"There's no need to wait for Labor to win government," Greens MP Vica Bayley said.

Mr Winter did not rule out introducing the legislation while in opposition.

Liberals previously accused of 'pork-barrelling'

It is not the first time that accusations of pork barrelling have been levelled towards the government.

In March this year, the Tasmanian Liberals were accused of attempting to "pork-barrel their way back into power" through a process by which election candidates could apply to get taxpayer-funded grants for community organisations.

At the time, the director of the Centre for Public Integrity, Geoffrey Watson, SC, labelled the move as "pork-barrelling, plain and simple".

In 2021 it was revealed that millions in the Liberal Party's election grants were doled out through a process that avoided parliamentary scrutiny.

And the state's Integrity Commission found the Liberal government's promise to deliver $21.4 million in regional grants were made without adequate transparency during the 2018 election campaign.
