The new playground under construction at the corner of Coral Street and Terranora Parade at Bilambil Heights has been vandalised overnight.
The vandals sprayed paint across the site, on the ground and on contractor's site equipment.
Council's Acting Manager Parks and Active Communities Murray Smith said it was a disheartening attack.
"The new park will become the main playground for local kids who are looking forward to its opening," Mr Smith said.
"This vandalism wastes people's time and costs money to clean up.
"It's disappointing someone in the community would do this, given the years of collaboration between local residents and Council to redesign this park."
Council workers will remove the graffiti and resume construction of the playground as soon as possible.
The new playground is due to open in June 2022.
