And they are urging farmers to speak up and report it as part of a community awareness campaign.
Four major crime areas of concern are being targeted - illegal hunting, stock theft, trespassing and firearm theft.
“Our farmers are under siege," NSW Crime Stoppers chief executive Peter Price 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,” he said.
“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.”
A NSW Police spokesperson said said rural crime had a devastating impact on farmers.
He encouraged property owners to install security cameras, make sure gates were locked and guns were stored safely.
“Make sure you report crime as soon as it happens as it increases the chances of recovering stolen livestock or firearms and catching the people committing these terrible crimes," he said.
The six-week campaign will provide information on how regional communities can deter or prevent crime in their area while encouraging the community to report crime – see something, suspect something, say something.
