For the second time in recent months, hoons have vandalised one of Wollongong's most popular green spaces, leaving a damages bill in the thousands of dollars.

It's sparked calls for public assistance to catch those responsible.

Cr Andrew Anthony said the driving of motor vehicles, apparently doing burnouts on the sodden grass banks near the Stuart Park picnic shelters at North Wollongong, was "selfish and reckless".

"It would be nice if people took more pride in their community," he said.

Inspecting the damage on Friday morning, Cr Anthony said: "It's going to cost council a lot of money to fix this mess and that money could be better spent elsewhere."

Council recently installed portable CCTV cameras following repeated acts of vandalism in the area at Galvin and Stuart parks.

At 10pm on 2 April this year, police apprehended a 19-year-old man from Scarborough who pleaded guilty to damaging property.

Police described the damage to the park as "extensive with large divots, track marks, and numerous holes in the ground".

Wollongong Police said they were aware of this week's vandalism and are encouraging the community to contact Crime Stoppers on 1800 333 000 if they see anything suspicious and to take note of the car description and number plate.

Council didn't confirm if their new cameras have captured the culprits of this week's attack, saying only: "Council shares any footage of vandalism incidents with NSW Police to support their investigations.

"Our teams will work to repair the grass as the grounds start to dry out over spring. The recent rains will help the areas to reestablish themselves quickly," a Council spokesperson said.

Cr Anthony said people he spoke with on Friday morning were disappointed with the frequency of the vandalism in the area.

"It's a beautiful area and people should take more pride," he said. "It's also a waste of police resources having to deal with these sorts of issues."

Cr Anthony hopes the arrival of the cameras might act as a deterrent as well as catching the culprits. 

"It would be a large area to fence off and I don't think that's practical. Young people just need to think more about what they're doing."
