Litter Data

The purpose of the National Litter Index is to provide insight regarding:


  • The presence of litter items at sites within broadly comparable regions.
  • Estimated volumes of litter objects within the litter stream, based upon a volume-per-item model.
  • The contribution of objects recognised within established litter categories to the overall litter stream.

The National Litter Index was used between 2005 and 2019.
