An Impossible Dream: Sustainable Pesticide Management in Great Barrier Reef Catchments?

An Impossible Dream: Sustainable Pesticide Management in Great Barrier Reef Catchments?

Ongoing pollution of the Great Barrier Reef (GBR) catchments has been documented in a new blog by Anthony Amis, a Friends of the Earth (FoE) Australia researcher who has been studying pesticides and water quality for more than twenty years. 

In July 2023, FoE published a blog on pesticides in Queensland water supplies. This was based on over 70,000 pesticide detections listed on the Queensland Government’s Pesticide Reporting Portal between late 2011 (in some locations) to March 2023. 

This new, follow up blog by Anthony Amis looks at the potential ecological impact of pesticides flowing down rivers and creeks into the Great Barrier Reef (GBR). It does not discuss impacts of pesticides on the GBR but rather hopes to facilitate a better understanding of what is flowing into the GBR.

A map of Queensland showing the 39 locations of pesticide sampling locations that FoE sourced from the Pesticide Portal. Average distance from the coast (excluding two locations near Comet) is ~10km, meaning greater potential impacts on the GBR. White pins indicate a location where pesticides were detected, but the average level detected over varying time periods did not exceed 99% or 95% default guidance levels (DGV's.) Yellow indicates sites where pesticides breached the 99% DGV and red pins indicate sites where both the 99% and 95% DGV's were exceeded.
