Zone coordinator for the Rural Crime Prevention Team, Detective Sergeant Damian Nott, said four major crime areas of concern are being targeted - illegal hunting, stock theft, trespassing and firearm theft.

"There have been instances of sheep theft, but the general range of crimes is not any higher or lower than anywhere in the state," he said.

"We have an unprecedented amount of focus and resources from NSW Police.

"We do have challenges with staffing levels in the Riverina within the Rural Crime Prevention Team. They are kept very busy at the moment."

Detective Nott said in the coming months a new rural crime investigator would be stationed out at Griffith.

His comments were made as a new state-wide campaign by Crime Stoppers and the NSW Police Force was highlighted at Henty in a move to encourage reporting of crimes.

NSW Crime Stoppers CEO, Peter Price, said residents in the Riverina and surrounds should report any illegal activity with all information treated in the strictest of confidence.

"Our farmers are under siege," he said.

"Already adversely affected by the drought, rural crime is having a significant and direct effect on the economic welfare of farmers and their families, and we need to do something about it.

"We don't want to know who you are, we just want to know what you know.

"Anything you have seen or heard could help police bring those responsible to justice."

Assistant Commissioner Geoff McKechnie said rural crime is continuing to have a devastating impacting.

"There are some preventative measures that can be undertaken such as installing cameras, ensuring gates are locked and in the case of firearm theft, ensuring guns are locked and ammunition kept separate to any firearms," he said.

"It is also important to report crime as soon as it occurs, whether you are the victim or you have witnessed a crime."
