The ballot paper order for the Senate was drawn through a method called double randomisation by the AEC in Hobart.

The Australian Conservatives Party will be first on the Senate ballot, with the Greens fourth, Liberal party fifth and the Labor party in ninth position.

Four ungrouped candidates, Independents Steve Mav and Francis Flannery, Australian Better Families' Greg Beck and Love Australia or Leave's Karen Street, will be listed after the 16 parties on the ballot paper.

AEC state manager David Molnar said the number of candidate groups at 16 is slightly down compared to the last election when there were 21 groups.

"To be fair the order is randomised, which column you get on the ballot paper. The order of candidates within each column is determined by the party," he said.

"The number of candidates in Tasmania is down in the Senate and slightly up in the House of Representatives."

Mr Molnar said the largest lower house candidate ballot was in Braddon with nine candidates.

"Compared to 2016, we had 30 candidates across all our divisions, this time it's 32 so it's slightly up," he said.

Tasmanian Greens senator Nick McKim said, given he only held his seat by 141 votes from One Nation last election, he is not taking anything for granted.

"Whether we are first or last on the ballot paper, we are just going to work hard and campaign for climate change," Senator McKim said.

One Nation lead Senate candidate Matthew Stephen said he was confident following the ballot draw, with his party to be listed 10th.

"I'm sure Tasmanians are smart enough to go through the ballot paper and find out who best represents them," Mr Stephen said.

The candidate orders for lower house ballot papers were simultaneously drawn across the state.

Mr Molnar said ballot paper production would begin Wednesday afternoon ready for voters to start pre-polling at major centres in Launceston, Burnie, Devonport and Hobart on Monday.

"Just in Tasmania, we will produce approximately 600,000 of each House of Representatives and Senate papers to allow us to distribute those across Tasmania and Australia," Mr Molnar said.

"There are currently 386,000 Tasmanians on the electoral roll, compared to last election it was 373,000. We've had an increase of 13,000 on the roll.

"Youth engagement has certainly picked up but overall with our population increasing we would expect an increase.

"Youth enrollment is now running higher than it ever has."
