About $1000 worth of damage was caused to the park overnight on Wednesday, which is undergoing a $100,000 upgrade.

"It was only last week that we announced the significant upgrade to the park and it is extremely disappointing to see this damage," Mayor Quilliam said.

"Young people from the Circular Head area have made a significant contribution to this project, including raising $5000, and while you don't know who did it, it seems a minority of people are willing to ruin things for everyone else."

The damage included: graffiti and footprints into freshly laid concrete and a large brick wall was also knocked over.

It is estimated that restoration works will be completed within a week, however, Technical Officer, Engineering & Projects, James Brewer, said it was a frustrating delay.

"As a result of this vandalism the skating surface has been damaged, which will take some work to repair," he said.

"We're hoping to fix the damage in a few days, but what must be made clear is that people need to stay out of the construction site mainly for their own safety."
