Karina Hughes' nine-year-old son has even offered to clean up the graffiti under the bridge leading into Eaglehawk - which Ms Hughes says makes her beautiful country town look like a city. 

She is calling on the council, police or even the community to band together to clean it up. 

"These vandals are ruining our towns," Ms Hughes said. 

"It's such a nice spot and children walk around there all the time but you can't admire anything with these offensive, ugly slogans everywhere.

"We can't let them get away with it and I think something can be done - we can clean it up."

V/Line is responsible for the site and has been contacted for comment. 

Senior Sergeant Craig Gaffee said graffiti was an ongoing issue in Bendigo but police caught between 65 and 75 per cent of offenders. 

"While graffiti is not as prominent in Bendigo, it remains an issue for us and the community because of the costs involved in repairing the damage," he said. 

"Graffiti is a serious offence and offenders can be charged with criminal damage, which could result in jail time or large fines."

But Ms Hughes said the problem was getting worse. 

"I would ask the police to put a camera at the underpass because they are there every night vandalising the area," she said. 

"I constantly have to explain to my son that it's wrong to draw on walls and he has been asking about the bad words too. 

"It's just not what we want to see in our town."

Senior Sergeant Gaffee said police patrolled known locations of high graffiti, which included public and abandoned buildings and public transport routes. 

"We take photos of all graffiti and tags we find and when we locate offenders, we charge them on all their offences," he said. 

"We get fantastic community support and they are quick to notify us because it doesn't happen all that often around here. 

"We just urge people to keep reporting it so we can report it and find the offenders."
