Manly Cove, one of Sydney Harbour’s most iconic swimming spots, has been revealed to be a microplastic hotspot, highlighting a widespread issue impacting popular coastal areas. According to a long-running survey conducted by AUSMAP, a project of Total Environment Centre, swimmers here are immersed in a soup of plastic pollution.
Since 2018, over 42 samples have been collected and analysed from the cove’s foreshore. The results are alarming: more than half of these samples contained very high levels of microplastics, with one sample recording an astonishing 4,097 pieces per square metre. These microplastics include industrial pellets, polystyrene foam, fibres, hard fragments, and artificial grass. The diversity of microplastic types reflects a wide range of sources, spanning multiple council areas within the catchment. Despite their varying origins, all pose a significant threat to marine life and human health.
Dr. Scott Wilson, AUSMAP’s Research Director, emphasised the gravity of the situation: “Manly Cove is very popular with residents and tourists, and we should be showcasing the best of Australia’s environment, not a plastic-polluted hotspot.”
Microplastics: A Local Problem with National Implications
Manly Cove’s predicament is not unique. Coastal hotspots across Australia are grappling with microplastic pollution, driven by a mix of human activities, poor waste management, and inadequate pollution controls. These findings underscore the urgent need for comprehensive action.
AUSMAP and the Total Environment Centre are actively working towards solutions, with current efforts focused on:
Banning intentional microplastics and implementing broad microplastic reduction strategies.
Targeting microfibre pollution from washing machines by advocating for the installation of filters and upgrades to wastewater treatment plants.
Intercepting pollution from rubber crumb and synthetic grass, commonly used on sporting fields, and promoting alternative materials.
Further restricting polystyrene foam use, which is a prevalent pollutant in coastal environments.
A Call for Collective Action
The pollution at Manly Cove serves as a stark reminder that preserving Australia’s natural beauty requires proactive measures at every level. From government policies to individual actions, we all have a role to play in reducing microplastic pollution.
“We’re committed to finding solutions,” said Dr. Wilson. “AUSMAP will continue to monitor hotspots like Manly Cove and release new findings from other locations across Australia in the new year. Together, we can protect our oceans and communities from the growing threat of microplastics.”
Manly Cove deserves to be celebrated for its natural beauty, not marred by the legacy of plastic pollution. Let’s ensure that future generations can enjoy its pristine waters and vibrant marine life.
