Aussie Farms is involved in a stoush with the federal government and National Farmers' Federation after starting a social media campaign it says is about exposing animal welfare breaches.

The Map includes farms from the Western regions of NSW.

Agriculture Minister David Littleproud has warned the map could cause the death of animals and pose biosecurity risks by encouraging vigilantes to break into properties to document farming practices.

NFF president Fiona Simson said vigilantes have regularly trespassed on farms, which are often producers' homes.

Aussie Farms founder Chris Delforce said those concerns were irrelevant because his group was not interested in farmers' homes.

"I don't think anyone would really buy that they're concerned for their safety from a group of peaceful, non-violent activists," he told ABC Radio's Radio National.

Mr Delforce admitted some of the information on the map, which has been criticised over inaccuracies, was outdated and could be wrong.

"We're providing information that we've received that we've been able to collate publicly. We don't know if it's still accurate now," he said.

"We encourage anyone to submit more accurate information so we can keep it up to date."

Mr Delforce said calls for Aussie Farms to be stripped of charity status were expected because they were taking on a "Goliath empire".

He said the group would not take the map down, claiming most Australian farming was done on "mega-factory" operations with sometimes more than a million animals.

"I believe people have the right to see what modern farming looks like," Mr Delforce said.

He defended trespassing on farms, saying most people would think jumping a fence to document cruelty was less of an offence than animal welfare breaches.

Greens leader Richard Di Natale told the ABC highlighting animal cruelty was important but activists needed to be careful information was accurate.

Pauline Hanson said the activists wanted to stop people from eating meat.

"A lot of these idiots who live in the city have no idea or understanding the life of a farmer. The fact is, through the farming sector we have food on our table," the One Nation leader told Sky News.
