Western Bay's district council is cracking down on people dumping pre-paid rubbish bags at the ends of rural roads.
The council is asking people to dob in anyone seen dumping bags by recording their car registrations and taking photos of the culprits.
If identified, they could be fined up to $500 under the Litter Act.
Ilze Kruis, leader of the environmental solid waste team said people were leaving bags throughout the week.
They became unsightly, smelly and often ripped apart and spread around by dogs.
