"Our farming families provide the community with essential food and fibre, and are the life blood of our regional communities," Mr Jackson said.

"We need a strong and national consistent approach to ensure all farmers have equal protection."

NSW Minister for Agriculture Adam Marshall said the Criminal Code Amendment (Agricultural Protection) Bill criminalised using a carriage service to incite trespass and/or other property offences on agricultural land.

Penalties of up to five years imprisonment apply Aussie Farms, the organisation that recently published details of Australian primary producers online, are exposed to potential penalties of up to $2.1 million.

Mr Marshall said the new law would fit neatly around an announcement he would make about State Government changes to the physical act of trespass in a few weeks time.

"It's already illegal to trespass on a farm, just as it is illegal to go onto someone's property, no matter where it's located, without permission of the landholder," he said.

"That's an offence of trespass under the Crimes Act 1900, or in a rural sense, aggravated trespass.

"But I'll be making an announcement very shortly. I've been working on this since my appointment, talking with a number of key stakeholders about this."

Mr Marshall said he was very keen to enshrine in law our farmers right to farm.

"And that includes farming the land and growing food or fibre without fear of interference by other people who want to illegally enter their property to interfere with their operations and threaten bio-security," he said

"And biosecurity is critical, particularly if you are in intensive agriculture, because it keeps your property viable.

"If it is breached your property could be be shut down."
