Senator Di Natale will mention how the federal Coalition, after successfully opposing the previous Labor government's attempts to limit poker machines, announced its alternative policy before the last election on the Clubs Australia website.

"Australians are over it. When wealth and power are concentrated in a few hands, and they wield that power for their own narrow interests, democracy cannot flourish," he will say.

'Put nation first'

With the election less than two weeks away, the national polls have the major parties tied on a two-party-preferred basis. While this would indicate a tight result – even a hung Parliament – is likely, the internal polling of both sides, which tracks key seats, has the Coalition sitting on a modest but comfortable majority.

Labor suffered politically for forming a coalition with the Greens after the 2010 election produced a hung Parliament and has vowed to either govern alone or not at all. The Greens and the Coalition have both ruled out doing a deal with each other.

With numbers tight in both houses, Nationals leader Barnaby Joyce, in a National Press Club speech on Wednesday, implored voters in his former state of Queensland considering voting for Pauline Hanson to put their country first.

Mr Joyce, who represented Queensland as a senator for almost nine years before moving to the NSW lower house seat of New England, said Nationals candidates in Queensland may not have the profile of Ms Hanson but were solid operators.

"Ms Hanson will run her race. The others will run their race too. I think that after the fury and the colour, people may quietly just assess what is truly not only in Queensland's interests but, most importantly, what truly is in our nation's interests," he said.

"So often you are not just voting for your electorate, you are not just voting for your senator, you are voting for the nation of Australia.

"First and foremost vote for your nation."
