The vehicles were seen coming out of Callala Beach and motorists may have passed them on Callala Beach Road, Coonamia Road or Forest Road.

The appeal comes from police after an alleged assault of a 68-year-old farm manager on a property near Culburra Beach on Saturday, May 5.

The man had come across a group of eight or so young men and adults riding trail bikes, quad bikes and driving a buggy on the private property near Lake Wollumboola.

The manager spotted the riders during a regular inspection of the property and after confronting the group, where one bike was struck, he was allegedly punched through the window of his ute and a piece of pipe was thrown through one of its windows.

One of the group allegedly jumped on the bonnet of the vehicle, kicking in the windscreen.

The keys were also taken from the vehicle’s ignition and thrown away and the man, who suffered minor facial injuries, later discovered his mobile phone was also missing.

“It was pretty scary and confronting,” he said.

“I was just making sure the property was safe. These guys were illegally riding on the property, ripping up the area.

“To one of the rider’s credit after the group left he returned to see if I was okay.”

The man was forced to walk back through the property to raise the alarm with police.

Officers from the South Coast Police District attended the location and carried out a number of forensic procedures on the vehicle but had no leads as to those involved.

However a group of four-wheel drive vehicles, with light bars, carrying and towing motorbikes and a buggy were seen leaving Callala Beach later in the day.

Anyone who may have any footage who may help identify the group is asked to contact Nowra detectives on 4421 9699 or Crime Stoppers on 1800 333 000.
