Calls to investigate South West Rocks’ microplastics problem

Microplastic contamination in South West Rocks is set to go under the microscope, following an unwanted top 10 rating earlier this year.

In March, a technical report from the NSW Government identified South West Rocks Creek - known locally as Back Creek - as the seventh most microplastic-contaminated waterway in the state, from 120 tested, based on the concentration of microplastics per cubic metre. 

The nearby Saltwater Creek also recorded a “high” result for microplastic pollution, while waterways further north in Mullaway (Darkum Creek) and Coffs Harbour (Coffs Creek) received “very high” ratings. 

Council action: At a meeting on June 16, Kempsey Shire councillors resolved to seek support from the NSW Environment Protection Authority (EPA) and state government for further investigation into contamination sources. 

Council will also pursue community education programs and request the inclusion of additional waterways in future monitoring programs, such as Killick Creek at Crescent Head, Korogoro Creek at Hat Head and Fishermans Reach.

In Coffs Harbour, councillors resolved at their April meeting to explore microplastic management options for their local area.

Multi-faceted problem: Kempsey Shire councillor Alexandra Wyatt said “microplastics can affect the growth, health and reproduction of aquatic species, while contamination can undermine the reputation and marketability of seafood products. Our businesses, accommodation providers, tourism operators, fishers, oyster growers and local farmers all depend on a clean waterway and healthy coastal environment”.

Plastic problems: Local Peter Holmes said plastic pollution can often be seen on South West Rocks beaches, particularly after rough weather.

• “When you walk along the beach there are still lots of little bits of plastics floating around - partially degraded plastics, brittle bits of plastic,” he told the Mid North Coaster at Back Creek on Thursday. 

According to the EPA, the most common types of microplastics are fragments (37%) and foam (37%), followed by plastic film (19%), artificial turf (5%) and pellets (2%).
