It comes with Keith Pitt's appointment as federal water minister, with the former minister David Littleproud now the Nationals Party deputy leader and agriculture minister.

Irrigator Leo Ieraci helped coordinate Griffith's convoy team, and says if the government continues to "play games", there will be no choice but to knock on their doors again.

Key groups in the Riverina have called for an "immediate visit" from Mr Pitt, while last rally's organisers saying they will not accept a 'softly softly' approach.

"We are extremely concerned about Keith Pitt's appointment... although we are hoping he proves us wrong," rally co-organiser Jan Beer said.

"[Farmers] are concerned at the potential consequences, with some farmers saying there needs to be civil disobedience before the Federal Government will take the necessary steps to address their issues.

"It appeared some progress was being made, at long last, with David Littleproud.

"So is this a ploy to get Mr Littleproud out of the firing line and further stall any efforts to fix the Basin Plan? It certainly looks that way."

Mr Ieraci said a lot depended on the results from the inquiry and Mr Keelty's report, as well as whether or not Helen Dalton's water register gets implemented.

"Littleproud has walked away from a big, complicated thing and hasn't hung in. We are serious about this, and they are passing the buck on," he said.

"They had Littleproud in charge, now they have an apprentice... It looks like they are wasting our time and bluffing."

"We're talking about our livelihoods - farms, businesses, jobs, communities - we are all suffering."

"If they continue to play games, we are going to have to go back to Canberra. It's that simple."

Speak Up chairwoman Shelley Scoullar said the group would've preferred the new minister to be someone from the southern regions, with a better historic understanding of water.

"But if we have to have another northerner - the third in a row - we want to ensure he is well versed on our unique issues."

Southern Riverina Irrigators chairman Chris Brooks said in recent months progress had been made in discussions with Mr Littleproud, in particular through his appointment of Mick Keelty as the Inspector-General of the Murray-Darling Basin.

"Now [Mr Littleproud] has not seen the Keelty process through, which was his promise to engage with us," Mr Brooks said.

"We look forward to discussions with [Mr Pitt] in the very near future."
