Mr Hansen has challenged politicians to front up, spend ten minutes with him and answer some tough questions about water issues.

He has labelled the question and answer session 'Ten by the Tank' and will live stream the events.

"With water management and river health the talk of the nation on the back of native fish kills at Menindee, Lake Keepit and also a Lake Burrendong, I felt that I needed to know what our candidates proposed to do for our rivers," he said.

"I felt that people who have a love of our rivers, as I do, needed to know what we were getting when we cast our vote, so the idea of ten by the tank was born. 

"The tank is a fitting place to discuss river management, as my pet Murray Cod 'BragMat' is from the first ever batch of fingerlings we released when the Inland Waterways formed. He was just 50mm when I got him, but he is now almost nine years old, and to me, he is a reminder of the work we have done for the local river."

Mr Hansen hopes the interviews will help viewers decide who to vote for on March 23.

"I hope that these interviews give me surety in who I am voting for, and ultimately help to reveal the best candidate for the region," he said.

"It could change the way I vote because I still haven’t decided who to vote for, as it’s a complex and changing political landscape at the moment. By the last interview, I should have an idea."

All five candidates have accepted Mr Hansen's invitation and he did a special interview with Labor's Chris Minns.

"The shadow water minister Chris Minns happened to be in town just after we announced the interview series, and the opportunity was too good to miss, so we did an extended interview that went for almost 30 minutes," he said.

"We spoke on everything from the Murray Darling Basin plan to his goals and aspirations for the state outside water management. He didn’t have the questions beforehand, and some of them were fairly complex, I thought he did quite well."

Mr Minns said he enjoyed talking with Mr Hansen.

"It was good to talk with Matt and I told him if there is a scientific backed process that can save a significant amount of water for regional communities Labor will back it if elected," he said.

"When you think about the money being spent on water technology if there is an innovation that can change the game in regards to water management we will adopt it, we would be crazy not to. But, there is no silver bullet fix, if there were it would already be in place."
