This report presents the findings of Australian Litter Measure litter surveys completed by Perth NRM across the Perth metropolitan area during the 12 months to June 2024. To date, five bi-annual surveys have been completed using this method and this report includes the full results of the November 23 and May 24 surveys, as well as a preliminary overview of trends/patterns seen across the five surveys completed to date.
For 2023/24, across 107,677 square metres surveyed, 10,700 items of litter were counted, with a calculated volume of 740.99 litres.
Cigarette Butts and filters were found to be the most common item by count, while Construction Materials were the highest item by volume. On a raw basis, Industrial sites contained the highest litter by count and volume, however once figures are normalised to account for the varying square metres surveyed, Retail moves into top spot by count. Beaches had the lowest litter levels by count and volume. Plastic represented the highest material found by count (56%) and volume (32%).
In this report litter data has been provided by site types and key categories to establish a basis for trend analysis under this newly developed litter count method.
