Water quality monitoring

Duration 00:02:17

Water quality monitoring and the Great Barrier Reef.

With substantial investment and action underway to improve land practices, water quality and Reef health, we are tracking the work of many stakeholders by monitoring progress towards ambitious Reef targets.

Like all Reef action, there are many stakeholders involved in monitoring programs. Scientists lead the way and in some areas landholders and community members are also provided with training and support to help monitor the health of our waterways. Protecting the Great Barrier Reef requires the efforts of many.

The Paddock to Reef Integrated Monitoring, Modelling and Reporting Program (Paddock to Reef program) is a highly collaborative, world-leading program designed to collect and integrate data on agricultural management, catchment indicators and loads, and the health of the Great Barrier Reef.

Data is collected and reported across six Reef regions and results are then published in a report card. This program measures progress against the water quality targets and actions under the draft Reef 2050 Water Quality Improvement Plan.

Jointly funded by the Australian and Queensland governments, The Paddock to Reef Program also involves collaboration with industry bodies, regional natural resource management groups, landholders and research organisations.

eReefs is a leading program that combines technologies and marine modelling to paint a picture of what is happening on the Reef today and what is predicted to happen in the future. This broad picture helps to forecast bleaching and severe weather events that affect the Reef, manage responses to maritime incidents and inform reporting on the health of the Great Barrier Reef.

eReefs is a collaboration involving the Great Barrier Reef Foundation, CSIRO, the Australian Institute of Marine Science, Bureau of Meteorology and Australian and Queensland governments.

What you can do

From the Great Barrier Reef to Moreton Bay, all Queensland waterways are connected. For example, avoiding littering, wherever you live, will prevent litter getting into waterways and making its way to the Great Barrier Reef. If you live in Reef catchment areas, you can make sure soil and fertiliser stays on your property.

If you are interested in participating in monitoring in your local area or when visiting the Great Barrier Reef get started by exploring the following resources or do a quick online search.
