GRAFFITI along Wangaratta's iconic Bullawah Cultural Trail is an ongoing problem that council says ratepayers are footing the cost to remove.

The latest are graffiti images of genitalia on artwork of famous musician, former resident Nick Cave, and also damage to a floral painting.

Council will consult with artists to determine the best approach for the graffiti removal so the artworks are not altered.

Other damage is to the signage along the cultural trail that helps tell the story about the great significance of the First Nations People's connection to the area.

Council director of infrastructure services, Marcus Goonan, said it is "incredibly disappointing" and the reality is that the ratepayers end up paying for these acts of vandalism.

"From that point of view, it's completely unfair," Mr Goonan said.

"We manage the trail as we do with any other structure within the municipality and it's checked and reviewed, inspected in line with our road management plan.

"We rectify any defects that we find and we're more than happy for people to put in CRs (customer requests) whether it's graffiti or change over signs."

Mr Goonan described the pieces of art as "really quite important pieces" within the rural city and they're engaging the original artists to fix the problem.

"This is so because when we do clean those up they'll be back to how they were rather than having our field services guys come in an potentially make it worse," he said.

"This is the first time that I know of that the Nick Cave one has been vandalised and as a general rule the community have a very strong affinity with the Nick Cave piece and the flower piece.

"I think they are important to the community so they're not vandalised (more regularly) like our underpasses occasionally are.

"It's the first time I've seen it (on art pieces) and if it kept happening we would look at doing something because graffiti treatments are incredibly expensive.

"We understand that some of those signs have been graffitied a few times, but we can just clean those off."

The latest works of the establishment of a new playground at Apex Park incorporated Indigenous aspects such as totems and a koala, so it too could connect well to the Bullawah Trail.

The playground, the Marmungun Rock, Indigenous sculptures, signage and footbridges join the First Nations story within the Bullawah Cultural Trail are all facets that Mr Goonan said shows what Wangaratta has to offer.

He said the notion of installing CCTV cameras to deter or apprehend offenders is not an option at this stage as they would be difficult to install in the natural environment and they could pose privacy issues.

"If we were seeing some really consistent vandalism then we'll look at other options to get a better outcome," Mr Goonan said.

"The reality is that it is fairly isolated on those paintings and other graffiti along the trail that we do know about."
