TASMANIANS will deliver their verdict today in five electorates set to play a critical role in determining who becomes leader of the country.
More than 362,000 voters in the state will head to the polls in this hotly contested federal election.
By lunchtime yesterday 21,500 had already lodged their ballot papers at one of several pre-polling stations and 22,700 had sent in postal votes.
Counting will start as soon as the polls close at 6pm, with the first results trickling in soon afterwards.
Counting will continue until midnight, but if the polls are accurate, the public will know who will be prime minister for the next three years much earlier.
Polls have consistently predicted the Coalition is on track to win in a landslide.
In Northern Tasmania, Bass and Braddon voters are expected to dump incumbents Geoff Lyons and Sid Sidebottom, while it is less certain if Lyons MHR Dick Adams will survive the national swing towards the conservatives.
In the South, Denison independent Andrew Wilkie is favourite to win with an increased margin while Julie Collins, the only Tasmanian minister in the federal Labor government, is no certainty to hold her seat.
The Senate contest is shaping as one of the most interesting races with an intense battle for the sixth spot between the Greens' Peter Whish-Wilson and Lin Thorp.
They are just two out of a record 54 candidates on the 90 centimetrecom900 millimetre-long Senate ballot paper.
Australian Electoral Commission state manager Sandra Riordan said people might get a surprise at its size when they were handed their Senate ballot paper.
Ms Riordan said Tasmanians had a good record for high voter turnout and low informal votes, which she was confident would be continued today.
She said the AEC had worked hard on engaging all sectors of the community.
