Mr Gee has long been favoured to retain the seat he first won in 2016, and was installed as a $1.25 favourite in a market framed by online betting agency sportsbet as recently as this week.

But the former member for Orange on Friday admitted the reactions of voters to volunteers manning pre-poll centres had been mixed, making it difficult to assess his chances of retaining his place in Parliament.

He said there were a lot of very informed voters in Calare, and he had got his messages out to the public, but the election's outcome was difficult to gauge.

"A very large number of people are walking into the polling booths and not taking anyone's 'how to votes', and I think that that means it's hard to say what people are doing," Mr Gee said.

"Then some people take all the 'how to votes'. I think the outcome's up for grabs."

Mr Romano, who has spent the last three weeks door-knocking across the electorate, said voters had warmed to his and the Shooters, Fishers and Farmers Party's messages.

"It's been personally satisfying to know that what I've been doing, people are receptive. I'm trying to make changes in Calare," he said.

"If I get the opportunity to be elected, you will see a difference and I'll be exactly like [member for Orange] Phil Donato. He gets in there and he fights and I'll be doing exactly the same."

Labor's Jess Jennings said it was time for a change of leadership in Calare, and the Nationals were "severely on the nose" with many people in the state.

"They've not put country people first when it comes to school funding, educational funding, or hospital funding," he said.

Mr Jennings said Labor's focus of "proper funding" for schools and hospitals, along with action on climate change, had received a positive reaction from voters during pre-polling.

In his last message to voters, Mr Jennings said: "If you want to stop the cuts and chaos put the Nats last, vote for Labor".

Mr Gee, however, said voters only needed to look at his "great runs on the board right around the region" to see how he and the Nationals had delivered for the electorate.

Mr Romano said Calare's biggest issues were infrastructure, water, roads and jobs.

There are seven candidates for Calare, with Shuyi Chen of the Christian Democratic Party, United Australia Party candidate Beverly T Cameron, Stephen Bisgrove of the Liberal Democrats, and The Greens' Stephanie Luke joining the other three on the ballot.
