TASMANIA faces uncertainty over coming days and probably weeks, with voters making no clear decision on Saturday who they want to govern their state. 

A likely ten-ten-five split of seats means they haven't given a clear mandate to Labor, the Liberals or the Greens, to govern the state.

The close result means neither Liberal leader Will Hodgman, nor the Labor incumbent David Bartlett,  know whether they'll go to the Council of Australian Governments meeting next month.

Prime Minister Kevin Rudd's already pushed back the meeting a week to April 19.

The results in two state seats remain in doubt and experts say it could take weeks before they're decided.
