Four bid for federal seat of Riverina

The Nationals' Michael McCormack drew the number one spot on the ballot paper, followed by the Greens' Michael Bayles, Labor Party's Mark Jeffreson and United Australia's Richard Foley.

On Wednesday, Mr McCormack reminded constituents about his work in improving infrastructure, health and economies across the electorate.

"I've been delivering for the Riverina since I was elected in 2010," he said.

"You only have to look at the record amount of funding that we've invested in hospitals, in schools.

"[There is a] 25 per cent increase in the Roads to Recovery funding for each of the 12 local government areas that I represent."

UAP candidate Richard Foley said the party has "policies I believe are going to fundamentally transform this country".

"This country is in peril and it needs a total change of direction and neither of the major parties are going to give us that," Mr Foley said.

"Our intent is to be holding the balance of power at the next government. We've got empty dams; rivers drying up; and, scandals left, right and centre."

With comments that the limited number of candidates was a result of The Nationals' stronghold on the seat, ALP candidate Mark Jeffreson said it was only the incumbent Riverina MP who thinks The Nationals were safe in the electorate.

"We think that regional Australia has been let down by The Nationals," Mr Jeffreson said.

"He has nothing to say about climate change except we should all pray for rain - that's not a solution to it.

"We're the only ones taking reasonable and proper actions on mitigating climate change."

Greens candidate Michael Bayles said this election will be fought on the major issue of climate change.

"We've got a plan to tackle all that with our climate change policy - to transfer over to renewables by 2030," Mr Bayles said. We've got a fully costed plan and in doing so, will generate 170,000 new jobs."
