Ms Davey is expected to be elected as the state's fifth federal senator and has requested her office be located in Deniliquin. The last NSW Nationals Senator John Williams was based in Inverell, in the state's north.

"I will be the only NSW senator based west of the Great Divide," Ms Perin said.

"I have a huge responsibility to represent the interests of all of our state regionally, but that's why I put my hand up. We need that strong voice, and I'm hoping to be that strong voice."

Ms Davey said she was proud to be able bring new federal agriculture minister Bridget McKenzie to Leeton and the MIA on Tuesday. She said growing rice was something she was passionate about.

"But there is also all the other regional industries, we've got cotton and then inland aquaculture, cereal, maize, all the livestock dairy.

"The more we can show that we believe in the regions, then there's more incentive for private investors to come out here."
