Local governments in Tasmania have trimmed the fat from their own top jobs, the state will now run with 18 fewer councillor positions in this October's local government elections.

The cuts are the result of a recent Local Government Board review of Launceston, Brighton, Dorset, Derwent Valley, the Southern Midlands and the Waratah-Wynyard Councils.

Three of the council areas say they could not run any leaner, and have kept their numbers unchanged.

There was room to move in Waratah-Wynyard, whose councillors will be cut from ten eight; Southern Midlands drops from nine to seven, and Derwent Valley will lose one from its nine current councillors.

The review follows on from similar efforts back in 2012, which saw 13 positions cut across six other councils.

The major areas of Launceston and Hobart will be Tasmania’s only 12-member councils after the latest review. After the upcoming election, four other regions will have less than their current twelve.

A few residents say the measures do not go far enough to fight the worsening economic situation in the state.

There are some who argue that a region holding just over 500,000 people should not have to sustain three levels of government, and have called for the abolishment of regional councils entirely.
