Volunteers can meet at Muswellbrook Skate Park in Rutherford Road at 9am on Sunday to assist with the removal of the extensive vandalism.

Mining group SubZero has offered its support to the program, with about 20 workers set to participate on the day.

Nine sites will be targeted, including the Brook Street car park, a fence in Cassidy Avenue, and the Brentwood Street pre-school.

The event is a joint initiative between the NSW Government and Rotary Down Under.

It is supported by a range of organisations including the NRL, Scouts Australia, Girl Guides NSW & ACT, Australian Men’s Shed Association (NSW Branch), PCYC, NSW Police, high schools and local councils.

Upper Hunter MP Michael Johnsen said the day was a chance for the community to send a message.

“Graffiti is an ugly stain on all communities and that it is frustrating for people to see homes, businesses and public amenities vandalised for no reason,” he said.

“Graffiti Removal Day is an opportunity for volunteers to show pride in our Upper Hunter communities and send a message to vandals that their destructive and criminal behaviour won’t be tolerated.”

To volunteer or nominate a clean-up site, complete the online registration form at www.graffitiremovalday.org.au, or register on the day.

A barbecue has also been organised at the skate park from 1pm.
