The Port News' koala sculpture, Scoop, was damaged as was Celtic Koala when the sculptures were ripped from their plinths on the Town Green.

The sculptures have been repaired and will return to the Town Green this morning.

Hello Koalas Public Art Project and Partnership Program project manager Linda Hall said the vandalism seemed to be random.

"The upside is we've been able to fix them pretty quickly," she said. "The damage was superficial on the artwork and we need to reapply them to the plinths."

Only two of the seven sculptures on the Town Green were damaged.

People have condemned the vandalism in comments on the project's Facebook page.

The Hello Koalas Public Sculpture Trail is a public art project with 50 fibreglass koala sculptures, painted by artists, in prominent positions across the area. Ms Hall said the interest and positivity about the project outweighed one stupid incident.

"Everyone loves the sculptures and they are in awe of the artists," she said.

The Arts and Health Australia project has drawn international attention.
