The 2017-18 survey reports the results of biannual litter counts at the same, undisclosed 151 sites across Western Australia. While over time additional rural highway sites have been added, the heart of the survey remains and the NLI is Australia’s only long term, consistent survey of litter. Also unchanged is its aim to build a deeper understanding of what is being littered, and where, and how that is changing over time.
The 2017-18 National litter counts were conducted during November 2017 and May 2018.
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.
It is expected that the information derived from this research will be used by governments and community organisations to develop policies/ programs that will reduce litter and create increased pride in communities.
