Parramatta is set to become a pioneer among New South Wales councils by adopting Environmental DNA (eDNA) testing in its quest to enhance local biodiversity. This innovative approach, part of a comprehensive biological survey of waterways, aims to identify hundreds of species residing in the area’s creeks and rivers.
The essence of eDNA testing lies in its ability to detect genetic material shed by animals and plants into their surroundings. These DNA fragments, carried by water into aquatic ecosystems, are meticulously analysed and matched against a vast database, akin to a forensic investigation of nature’s diverse inhabitants.
City of Parramatta Lord Mayor Cr Pierre Esber expressed his enthusiasm for the project, stating that the survey will act as a crucial benchmark for assessing and improving the biological health of local waterways. “This survey will offer a detailed insight into the biodiversity of our creeks and rivers. It holds the potential to uncover endangered species, enabling us to take protective measures, as well as identify invasive species for effective management,” said Cr Esber.
The survey’s findings will be instrumental in shaping both current and future water management strategies, ensuring the preservation and enhancement of river environments and water quality, which are vital to the Parramatta community.
Specialist consultants Stantec have been commissioned to conduct the survey, with sampling scheduled for April and October of this year. The study will encompass 20 sites within the Parramatta Local Government Area, with the results set to be compared with data from similar surveys conducted in 2010 and 2018 using traditional methods.
This pioneering initiative by Parramatta underscores the council’s commitment to leveraging cutting-edge technology for environmental stewardship, setting a precedent for sustainable urban development and conservation efforts.

Dear Reader,The Indian Sun exists for one reason: to tell stories that might otherwise go unheard.
We report on local councils, state politics, small businesses and cultural festivals. We focus on the Indian diaspora and the wider multicultural community with care, balance and accountability.
