A new report released by AUSMAP — Do We Have a Microplastic Problem in NSW Coastal Waterways? — provides further independent evidence that microplastics are now widespread across NSW coastal waterways.
Of particular relevance to Natural Turf Alliance members is page 27 of the report, which identifies synthetic grass as an emerging source of microplastics, particularly in urbanised catchments.
Key findings highlighted in the report include:
- Elevated concentrations of synthetic turf fragments (“blades”) were recorded at several NSW sites, with some samples recording up to 2,500 synthetic grass blades per square metre
- AUSMAP notes that the combination of local stormwater inputs, rainfall-driven mobilisation, and nearby synthetic turf installations likely contributes to both the variability and peak fragment loads observed
Importantly, the report highlights that once microplastic fragments enter waterways they are persistent and difficult to remove, accumulating in sediments and coastal environments.
This report reflects growing scientific recognition that plastic-based surfaces can act as a source of microplastics beyond their installation sites, particularly where stormwater pathways connect sportsfields, schools and parks to creeks, bays and beaches.
Why this matters:
- Coastal and estuarine systems act as accumulation zones for microplastics
- Source identification is critical for preventative planning and infrastructure decisions
- Local surface choices can have catchment-wide environmental impacts
We encourage members to review the report directly and reference page 27 and Table 2 when engaging with councils, regulators, sporting bodies and community stakeholders.
Natural Turf Alliance will continue to monitor emerging research and advocate for evidence-based, precautionary approaches that protect waterways, community spaces and public health. 👉 Read the full report
