NO more warnings - that is the message from Jimboomba Police to people trespassing in the former pine plantation at Yarrabilba.
For years the land, owned by developer Lend Lease, has been frequented by trail bike riders, horse riders and 4WD enthusiasts.
It has also at times been a popular dumping ground for criminals looking to ditch stolen cars.
However, as more and more residents move into Yarrabilba, the police are stepping up patrols to put a stop to illegal use of the land.
The enforcement comes as Lend Lease has leased part of it for commercial cattle agistment.
Jimboomba Police Senior Sergeant Bill Sheehan said for the past couple of months police had given out warnings to people found on the land, had left warning notices on cars and explained to people why they would be giving out trespass notices.
However, that time has now passed.
"The time for warnings is now over, they are no longer appropriate," he said.
"The previous level of tolerance is not acceptable due to livestock being on the land."
Senior Sergeant Sheehan said having trail bike riders and 4WD users on land where cattle lived could produce major issues.
"The vehicles could destroy the cattle's food source, they could damage the cattle if they hit them and if fences get knocked down they could escape onto the road and cause a serious crash," he said.
Two trail bike riders were the first to receive trespass notices to appear in court two weeks ago, after police caught them on the land while conducting patrols.
While trail bike riders and 4WD users were the main target, police also wanted to reduce the number of burnt out stolen cars dumped on the land as well as the dumping of rubbish and chemicals, Senior Sergeant Sheehan said.
A Lend Lease spokeswoman told the Times Lend Lease was continuing to work with Jimboomba police to improve the safety and security of the Yarrabilba community.
