AN unapologeticly direct slogan, Hey Tosser!, can now be seen brandished across the city's public transport.
The slogan is part of a campaign by Dubbo City Council in the hopes more potential offenders will get the message of its litter reduction campaign.
Dubbo City Council's Stormwater Education officer Karen Hagan said littering was a serious issue that negatively impacted the environment and the city's image.
"The message will be hard to miss when Dubbo Busline buses following routes along Macquarie and Talbragar streets this week start displaying the Hey Tosser! signage, which expresses the overall condemnation of littering," Ms Hagan said.
"Dubbo is a beautiful city but we have to keep on top of the litter problem, and many local businesses agree."
Bob Berry Real Estate has been displaying the Hey Tosser! message on its digital window display in Talbragar Street since October to emphasise the importance of putting litter, particularly cigarette litter, in the bin.
"Dubbo is a thriving and prosperous regional city. Litter on paths and in gutters makes the city look unkempt, giving completely the wrong impression to visitors and potential investors," Mr Berry said.
The Bin Your Butts and Bat for the Macquarie River litter reduction campaign was made possible by a $48,420 grant by the NSW EPA.
The grant will also help pay for the purchase and installation of 36 new cigarette butt bins and new signage in the CBD.
This project is a NSW Environmental Protection Authority Waste Less, Recycle More initiative funded from the waste levy.
