Costco and community services: Jacqui Lambie Network makes budget demands

This follows analysis by consumer group CHOICE, which found Tasmanians were paying up to 25 per cent more on groceries than their mainland counterparts, despite earning 10 per cent less on average.

Miriam Beswick, Andrew Jenner and Rebekah Pentland said in a statement their submissions for the September budget were guided by community consultation and economic analysis.

This showed widening gulfs in living standards and economic conditions between Tasmania and the rest of Australia, but also between Hobart and the rest of the state.

In a statement the three MPs said their budget requests would address the "deteriorating economy, loss of population, and an increasingly difficult budget position" forecast by Saul Eslake.

"The JLN's budget bids focus on holding the Liberal Government to its commitments to the Tasmanians, prioritising the most vulnerable in the community," they said.

"The JLN budget submissions are heavily targeted at developing sustainable cost of living relief and addressing urgent needs in rural and regional communities."

The list put forward by the JLN MPs identifies road infrastructure projects statewide as the most in need of action.

This is alongside upgrades to Neighbourhood Houses, the Grassy Harbour Port expansion study, and further action on the Western Tasmania Strategic Regional Partnership.

Community legal services, environmental organisations, social and community services, and health and wellbeing services were also in need of increased funding, linked to inflation, according to the MPs.

This was alongside requests for more investment in programs rather than capital works and infrastructure, increased funding for Tasmania Police to increase rural staffing levels, and a "reduction in red tape" for major projects like those put forward by Abel Energy at Bell Bay and the HIF Manufacturing plant at Burnie.

Local governments also received a mention in the submission.

The JLN MPs asked the state government to take the needs and capacities of councils to deliver promises made by candidates during state elections, and to engage with them more frequently.

The projects the three MPs did not sign on to were the roofed stadium at Macquarie Point - pending a review - and the $100 million Chocolate Experience at Cadbury, describing the latter as "decadent".

In a statement, Treasurer Michael Ferguson said he "looked forward" to working with the JLN politicians over the coming months.

"I can confirm that the Tasmanian Government has received budget process submissions from the JLN," Mr Ferguson said.

"These will be considered among with others submissions as part of the normal budget process, however I welcome their initiative and commend their focus on improving the cost of living for Tasmanian families."
