Sheep and cropping farmer Greg Sandford has dressed up his late father's Mercedes to demonstrate the effects the plan is having on southern Riverina and Goulburn Valley farmers, while he participates in the 2019 Variety Vic Bash.
"They (the government) seem intent on doing all this environmental damage, running way too much water through the forest and just running it out to sea," he said.
"We can't work out what the government’s agenda is.
"It just doesn’t make sense.
"So I'm doing the Variety Bash and I just want to get the conversation going."
Mr Sandford explained why he went with the design on the car, with the help of Deniliquin signwriters Visattak.
"The car (sides) have got a big monster and it is consuming industries and communities and towns in its path, and it is passing out environmental disaster and bankruptcy and depression and suicide," he said.
"That’s basically the Murray-Darling Basin Plan in a nutshell. It’s a disaster.
"The back of the car has a tombstone which says 'Rest in Peace New South Wales rural communities' and on the front we’ve got a bit of a statement on the plan itself.
"Farmers don’t seem to be having much luck changing the politicians' minds, so once city people start realising the effects the Murray-Darling Basin Plan is going to have on their food supply and, in particular, the environment, hopefully they will start getting behind us as well.
"That’s probably the main aim (of me doing this)."
The 2019 Variety Vic Bash, which features over 500 people, started in Melbourne on August 20 and will conclude in Geraldton on August 29.
