Sohier Oval at Ourimbah is the latest in a string of vandalism acts where a car is driven onto a wet field and the turf is destroyed.

It comes after Northlakes Oval at San Remo, one of three sporting fields targeted in the first week of August, was destroyed in a similar way. 

Vehicles also gained access to Wadalba sports complex and Mascord Park, in Kanwal, and Don Small Oval, Tacoma, to drive across playing surfaces.

The council’s section manager of parks and sports fields, Keith Ollier, said groups may be forced to delay events planned to be held at the Ourimbah oval while it is repaired.

He said both of the grounds at Sohier Oval had received extensive damage and because of this, it was not safe for the public to use the fields.

“Both fields will need repairs, levelling out the surface of the ground, placing topsoil and fixing barriers before the oval can be opened, costing Council a further $3000,” Mr Ollier said.

“Vandalism across the Central Coast is rife at the moment. Money spent on repairing damage this month alone has climbed to $30,000. 

“These mindless attacks cost rate payers money, cost our staff time and disrupt the public from using our facilities.”

The council is calling on the community to help find the vandals. It is putting up a $20,000 reward for information that leads to an arrest.

The council’s administrator, Ian Reynolds, said he was concerned its assets were being targeted. He called on witnesses to the vandalism to phone police.
