As Deputy Prime Minister and Member for Riverina Michael McCormack kicked off his campaign with a pitch to regional Australia, other candidates have told the Cootamundra Herald what voters say are the issues.

Mr McCormack said voters had a "clear choice" about who they wanted to govern them.

He spoke about border protection, infrastructure spending and the announcement last week by Treasurer Josh Frydenberg that the Budget was expected to return to surplus.

He said the government had delivered "right across the regions".

Mr McCormack said the government had made $70 million available to address issues raised by a new report into the controversial Murray-Darling Basin Plan.

"I will certainly be working hard to ensure all regional Australians know the National Party is the party for them, is the party of choice, is the party for lower taxes, is the party of choice for infrastructure across the regions and I will be putting that to voters, seat by seat," he said.

Labor's Mark Jeffreson said a decline in services like schools and hospitals was the issue most often raised by voters.

"But the smaller the town, the more I hear it. These are communities that might only have one school, for example," he said.

Greens' candidate Michael Bayles nominated climate change as the biggest worry for voters, but said he was also getting a lot of feedback about the proposed Adani mine, which has been proposed for central Queensland's Galilee Basin.

"There is a feeling that approval for the Adani project is being rushed through," Mr Bayles said.

The United Australia Party's Richard Foley said he had heard a variety of concerns from voters, but high on the list was the cost of living, along with infrastructure, water and taxation.
