Minor parties and independents appear set for sizeable support at the Tasmanian election, with polling suggesting more than a third of voters will snub the Liberals and Labor.

The island state is heading to the polls on March 23, more than a year ahead of schedule after the minority Liberal government failed to resolve a stand-off with two crossbenchers.
