The 'Aussie Farms' group has stepped up its campaign against agriculture in the Riverina, urging supporters to file objections to development applications for piggeries at Matong and Harden.
The chief executive of the company behind the Matong piggery, SunPork Group, told The Daily Advertiser he hoped Wagga City Council would ignore objections from animal activist "terrorists".
"All of Australia has seen how these people behave," Robert van Barneveld said.
"They have a position on animal farming and none of their claims are relevant to the construction of our piggery."
In January, the group launched a website with addresses dozens of farms in the Riverina and the capacity to post hidden camera footage.
'Aussie Farms' is now urging people to sign a petition and object to SunPork's application to Wagga council for a $9 million expansion.
"(SunPork's) NSW Grong Grong facility has previously been exposed to the public including its treatment of pigs and piglets, and the death of around 500 pigs from heat stress when (Sunpork's) ventilation systems failed to raise any malfunction alarm," the online petition stated.
Mr van Barneveld accused Aussie Farms of exploiting the Grong Grong accident to target the Matong expansion.
"The points raised in the the petition are untrue and support the view that these people have no interest in this application, only an interest in promoting their own views," he said.
"One of their claims is around a very tragic event which was certainly beyond the control of any farmer and something nobody ever wants to see happen."
A similar petition has been launched in opposition to Blantyre Farms' application to Hilltops Council to expand its piggery at Harden.
The creator of both petitions, former Animal Justice Party state convenor Lisa Ryan, said she was a "rural person" and claimed Matong deserved "better and safer" jobs than the 13 positions from the expansion.
"It goes beyond the animal cruelty; it's about environmental vandalism and the people who may have water and soil impacted," she said.
Aussie Farms did not respond to a request for comment.
Mr van Barneveld said he was concerned about trespass by activists even if his company's development application was approved by Wagga council.
"The very unfortunate fact of being involved in animal agriculture is that we have that hanging over our heads every day," he said.
"Aussie Farms' map just makes it easier for terrorists to raid our farms."
Matong piggery petition creator Lisa Ryan said further raids would be "totally unnecessary" as activists had already collected footage from other farms.
Ms Ryan said she expected the "wealthy and powerful" Sunpork to fight the campaign "tooth and nail".
