Farmers across Australia have descended on Parliament House to protest federal rule changes.

At least 2000 people were at the rally, according to organiser the National Farmers Federation (NFF).

The NFF has published a list of grievances including water buybacks in the Murray-Darling Basin and a phased ban on live-sheep exports by sea.

Federal Member for Parkes Mark Coulton said people he met at the protest, including at least one person from Warren, were angry.

"They didn't want to give up a day at work to come to Canberra," Mr Coulton said.

"There was a big focus on the live-sheep trade in Western Australia being stopped, but with it no longer being a market option, that's going to impact on the price of sheep on the eastern states. So, that one has a direct impact on sheep producers in our area.

"I think we'll probably see a campaign now. Hopefully we'll see one from the famers organisations."

A convoy of about 100 trucks lapped the ring road around Parliament House before the crowd heard from farmer representatives and Coalition politicians including Liberal Party leader Peter Dutton.

State member for Barwon, Roy Butler attended the rally.

"We deserve to be respected. However, the reason why you are here today, the reason why I am here today, is because we feel like we are getting stiffed," NFF president David Jochinke told the crowd gathered on the lawns outside Parliament House.

"Any policy that they develop, and when I say 'they' I mean these people in the house behind us, needs to have their key stakeholder. And you know who that is? Us.

"We need to be at the table, that is where we are going to get outcomes."

The rally also focused on a move to remove the Diesel Fuel Rebate for farmers, changes to the working holiday visa rules and the "reckless" pace of renewables progress

NSW Farmers president Xavier Martin took aim at the Murry Darling Basin Plan, which aims to improve river health by limiting the amount of water that can be taken from it.

"You can't grow anything without water," Mr Martin said.

"The Murray Darling Basin Plan is one of these really bad ideas that are making things worse, madly modelled in the millennium drought, this plan has done little but cause crippling pain within our once-healthy Basin communities.

"They're just turning the tap off to the bush."

Irrigators council speaks against water buy backs

The NSW Irrigators Council joined the rally.

CEO Claire Miller said the water recovery measures environment must not have social or economic impacts on the Basin communities

“With costs rising across the board and many operations struggling to make ends meet, this could be the straw that breaks the camel’s back for many small to medium family farms,” Ms Miller said.

"Any water recovery for the environment must not have social or economic impacts on the communities that depend on water for their livelihoods. ABARES has already warned the Government that buybacks will drive up production costs, particularly for rice and dairy."
