FARMERS protesting against government conservation land grabs have protested outside NSW parliament.

The rally tool place on Macquarie Street about noon today.

Retired farmer Marshall Fittler from Goonellabah, in northern NSW, said a rural revolt was growing.

"If governments are going to lock up farmers' land they must compensate them for it," he said.

"This is rebellion from the bush in its embryonic stage, it will grow into a monster."

Grazier Peter Spencer, who held a 52-day hunger strike over land clearing laws, addressed the rally.

Mr Spencer, who confined himself to a three-metre square platform on a tower at his property at Shannon's Flat, near Cooma, until he came down on January 12, plans to go on a speaking tour through regional Australia.
