MANSFIELD police are investigating damage to the historic Stringybark Creek camping area in the Toombullup State Forest near Mansfield.
In the lead up to Christmas, vandals caused major damage to the historic campsite.
More than 200 metres of pine post barriers were damaged and more than 120 pine posts were ripped from the ground.
Department of Environment, Land, Water and Planning (DELWP) district manager – Goulburn, Lucas Russell, said: “The barriers and posts were used to separate camping and visitor areas at the site.
“This type of vandalism is senseless and has negative impacts for the broader community,” Mr Russell said.
“The damage bill will run into thousands of dollars.
