Improving water quality to protect the Great Barrier Reef

  • News

  • Heritage
20 April 2023

The Australian Government is investing an additional $150 million to improve the quality of water flowing to the Great Barrier Reef.

Poor water quality is one of the largest threats to the health of the Reef. Sediment and nutrient run-off into Reef catchments can cause higher algal growth, pollutant build-up, and reduce light for corals and seagrass.

This not only affects the species that rely on the Reef, but also compromises the Reef’s resilience to threats like climate change.

The funding will support initiatives to protect and restore land in catchments with the largest amount of fine sediment runoff, to improve water quality and protect the Reef.
