Sitting members Michael Polley, David Llewellyn and Heather Butler will battle each other and hopefuls Brendan Sullivan, of Port Sorell, Bec White, of Sorell, and Nick Wright, of Hobart, for a Lyons seat.

A Labor insider said that the party had to retain three seats in Lyons to have any hope of retaining its majority.

Mr Bartlett said that the Lyons candidates were an excellent blend of experience and wisdom with youth, energy and new ideas.

"This team also brings a terrific geographical spread in what is a largely sprawling regional and rural electorate," he said.

All members understood the importance of prosperity in regional towns to the future of Tasmania, he said.
