Community and Public Sector Union secretary Zac Batchelor said data from the Australian Public Service Commission showed more than 600 federal public service jobs had been lost in Tasmania since 2013 and the number of public servants in the North and North-West was the lowest since 2003.

He said 25 jobs have been lost from Centrelink at Kings Meadows in the past 18 months.

"The majority of staff at Centrelink in Boland St are now employed by a labour hire company and have no sick leave or holiday pay and you could convert 50 staff to permanent employees," Mr Batchelor said.

He said in the 2018-19 financial year Tasmania lost 158 Centrelink and Medicare jobs, the Department of Health workforce shrank by 30 per cent, the Department of Veterans Affairs by 23 per cent and the Bureau of Meteorology workforce by nine per cent.

"This is even worse than it looks, as many federal government departments have significantly increased outsourcing in the last 12 months in Tasmania," Mr Batchelor said.

"Tasmania has the second highest rate of unemployment in the country.

"Tasmanians, particularly in our regions, are crying out for jobs and investment in essential services that are in crisis.

"We hear a lot about jobs and growth from the Morrison government but all we see is an economy with stagnant wages growth and consumer confidence stuttering."

Mr Batchelor said Tasmanian Liberal members and senators needed to stand up for federal public service jobs instead of "cutting regional jobs".

Labor senator Anne Urquhart said the data showed a significant loss of jobs and a "shocking and growing trend of cutbacks to secure jobs, particularly in regional areas".

"We have the least amount of federal public service jobs in Tasmania outside of Hobart on public record," Senator Urquhart said.

She called on the federal government to immediately employ more staff.

"Commercial leases are far more affordable in regional Tasmania and it is a complete no-brainer to start putting jobs back into the communities that need them most," Senator Urquhart said.

A year ago a campaign was launched by the Liberal Senate team and the Tasmanian government to ensure federal jobs and agencies came to the state.

Senator Jonathon Duniam hit back.

"Labor has no credibility when it comes to jobs in Tasmania and still have no plan to create jobs full-stop," Senator Duniam said.

"Since the Coalition Government was elected in 2013, employment in Tasmania has increased by 8.1 per cent. That's an extra 18,600 jobs that Tasmanians didn't have under Labor.

"While Labor continue to sulk and throw stones from the sidelines, the facts are there are more Tasmanians employed now compared to when Labor were in office and we will continue to work hard to create even more for Tasmanians."
