Improving water quality

We are improving water quality flowing to the Great Barrier Reef. This will build its resilience in the face of other threats including climate change, natural disasters and impacts from direct use.

We invest in programs to address water quality issues. The Reef 2050 Water Quality Improvement Plan guides our work. Our investments are underpinned by the latest science. We also monitor and measure our progress towards water quality targets.

(BACKGROUND MUSIC)

DESCRIPTION: An aerial view of a river running past farms to an estuary river mouth with mangroves flowing out to the ocean.

NARRATOR: Water quality is essential to the health of the Great Barrier Reef.

DESCRIPTION: Cut to a view under the waves of a mangrove and seagrass bed off the coast of Queensland. A dugong, clownfish, and several other sea creatures swim by. The vibrant coral reef is full of life and activity.

NARRATOR: So how do we protect it?

DESCRIPTION: A satellite view of a map of Queensland highlights the catchment areas. Flowing rivers appear at random, connecting until they all flow out into the ocean and Reef.

NARRATOR: Human activities within 35 inland water catchments affect the health of the Great Barrier Reef.

DESCRIPTION: Bird-eye view of green farmland covered mostly by patches of trees with a river running through. As the narrator speaks, trees begin disappearing. Farms, paddocks with animals, roads and cars begin appearing. Bare soil erosion flows from each of these additions into the river.

NARRATOR: Land clearing and certain farming practices cause soil and chemicals to run off into the Reef.

DESCRIPTION: Cut back to a view under the waves of the ocean. A brown cloud of sediments, fertilisers, and other pollutants hover over the fish and reef. All the marine life swims away and green algae begin covering the reef. The water is now dull and murky, full of floating bits of algae.

NARRATOR: These sediments, fertilisers, and other pollutants smother our corals and block their sunlight, increasing algal growth.

DESCRIPTION: We travel through a vibrant mangrove with a dugong, turtle, schools of fish, and fish eggs in the seagrass. A dark cloud of sediment and pollutants floats through the water. This cloud drives marine life away, leaving an alga covered area unfit for breeding.

NARRATOR: They weaken the growth of sea grasses and mangroves that sea turtles, fish, dugongs, and other marine life need as vital breeding ground.

DESCRIPTION: A close up of a crown-of-thorns starfish slowly crawling up and over living coral. In its wake is a trail of dead and whitened coral. As the camera continues to pan across the reef, we see barren and bleached coral reef, devoid of marine life.

NARRATOR: And they create the perfect conditions for crown-of-thorns starfish outbreaks that destroy coral colonies. This all reduces the resilience of the Reef to withstand future damage from climate change.

DESCRIPTION: We are now on the shore watching tourists on a marina. On the water is a business fishing boat, a recreational fisher is near the wharf, a boat ride owner is on the dock talking to interested tourists, and a master reef guide is talking to children about turtles.

NARRATOR: Poor water quality also impacts reef-dependent industries such as tourism, fishing, recreation, and scientific research.

DESCRIPTION: A dark reef scene plays in the background as six circles appear containing people representing each of the groups the narrator mentions. As the circles appear, the background ocean scene gets lighter.

NARRATOR: To address this challenge, we’re working with natural resource managers, Traditional Owners, farmers, land holders, reef guardians, local government, and non-government organisations to turn the tide on water quality.

DESCRIPTION: The scene cuts to a degraded barren riverbank with a wetland in the landscape. Soil trails flow from the bare soil bank into and down the fast flowing river. The river slows down as elements of restoration build up, giving the riverbank and wetland a chance to grow more vegetation which stops the flow of soil down the river.

NARRATOR: We’re investing to repair and rehabilitate catchment areas to slow the movement of water into the Reef by restoring riverbanks, stream banks, gullies, waterways, and wetlands.

DESCRIPTION: An educator talks about preventing pollutants from getting into the rivers with partnered farmers on their farm with their kelpie dog. Icons representing methods, profitability, and sustainability appear as the educator keeps talking to the farmers. The camera zooms in further as the educator continues talking about pollutants and biodiversity.

NARRATOR: And we’re helping farmers to reduce runoff of soil, fertiliser, and pesticides which can also improve profitability and sustainability. The aim is to reduce pollution from agriculture, urban and public land, and increase biodiversity.

DESCRIPTION: We are back to the aerial view of a river running past farms to an estuary river mouth with mangroves, flowing out to sea. The camera pans back down under the ocean waves. Dugongs, octopuses, several types of fish and a vibrant coral reef flow through the camera view. Icons representing tourists and industry appear along with two bubbles that say, “2m+ Tourists Per Year” and “60k Jobs Per Year”.

NARRATOR: Improving the quality of water flowing to the Great Barrier Reef helps to restore coastal ecosystems, vital for more resilient and healthy coral. A healthy Reef also supports the livelihood of Australians through tourism, jobs, and our economy.

DESCRIPTION: The icons disappear, and life begins popping up everywhere along the coral. Two scuba divers swim among a turtle, octopus, manta ray and other marine life.

NARRATOR: Together, let’s protect our Great Barrier Reef for present and future generations.

DESCRIPTION: The Australian Government logo, Reef Trust logo, website URL, clown fish and sea turtle appear.

NARRATOR: Visit our website to find out more about the program and see how you can help.

Poor water quality impacts

Poor water quality impacts the health of the Reef. It also affects the Reef's ability to resist and recover from other stressors.

Nutrient and sediment run-off from the land within the Reef catchment contributes to poor water quality.

Sediment can smother coral and restrict the growth of light-dependent plants, such as seagrass. Increased nutrients can create algal blooms, which are harmful to the Reef ecosystem.

Our investments

We invest in programs that are reducing nutrient and sediment run-off into inshore Reef habitats. We also invest in programs to monitor water quality and progress towards our Reef water quality targets.

Read more about some of these programs below or read the full list of Reef Trust water quality projects.

Evaluation of Reef Trust Water Quality investments

In 2022, the Reef Trust engaged Alluvium Consulting to evaluate and report on past and current Reef Trust water quality investments.

This Program is focused on remediating gully and streambank erosion in priority areas. This aims to significantly reduce the amount of sediment entering the Reef.

Sediment run-off is one of the biggest pressures on the Reef. Gully and streambank erosion contributes significantly to sediment entering the reef.

The investment program supports farmers to reduce run-off impacts from their properties. The program focuses on the adoption of more efficient farming practices. This includes the adoption of specific best management practices (BMP).

BMP investments support better, targeted nutrient management. Other BMP actions, such as irrigation channel modifications and planting layout or spacing modifications, help reduce soil erosion over time.

The program includes landscapes repair for eroding gullies and streambanks. This reduces sediment pollution flowing into the Reef, while improving land productivity.

Water pollution from urban and public lands is also addressed by the program.

The Partnerships support on-ground projects that address poor water quality remediation. This provides co-benefits for coastal ecosystems and species protection.

The projects are delivered through targeted procurement with National Resource Management groups across the Reef catchment area.

The projects involve working with farmers to boost biodiversity and reduce sediment erosion. The projects do this through:

  • Management practice change
  • Wetlands creation
  • Beach clean-up events
  • Habitat revegetation.

The projects also include engagement with Traditional Owner groups.

The Reef Trust Repeat Tenders engaged farmers to reduce pollutant run off by improving fertiliser application and related farm management practices.

The Program was highly effective and popular with canegrowers. It provided flexibility by allowing farmers to determine their own nitrogen use efficiency targets and cost-effective means of achieving those targets.

Reef 2050 Water Quality Improvement Plan

The plan guides how we work with industry and community to improve the quality of water flowing into the Reef. The plan identifies objectives and targets for all land-based pollution. It is based on scientific knowledge and understanding of water quality issues in the Reef, as set out in the Scientific Consensus Statement.

We released the plan jointly with Queensland government. The plan is reviewed every 5 years and is currently under review.

Read the Reef 2050 Water Quality Improvement Plan.

Scientific Consensus Statement

The Scientific Consensus Statement informs the Reef 2050 Water Quality Improvement Plan. It brings together the latest peer reviewed scientific evidence on the impact that land activities can have on Reef water quality and ecosystem condition.

The Scientific Consensus Statement is updated every 5 years to ensure water quality initiatives and policies are based on the best available scientific evidence.

The updated Scientific Consensus Statement is scheduled to be completed in late 2023.

Read the 2017 Scientific Consensus Statement.

Measuring improvements

To date, working with our partners has produced results, reducing pressures on the Reef. Regular monitoring will inform decisions for long-term solutions across the Reef.

The report cards measure progress towards the Reef targets and objectives. The report cards show the success of actions and inform further measures.

Science underpins the report cards. All results are reviewed by the Independent Science Panel.

Read Reef water quality report cards.

The Outlook Report is released every 5 years by the Great Barrier Reef Marine Park Authority. It provides an evidence-based overview that examines the Great Barrier Reef's health, pressures, and likely future. This report influences government policy and informs reviews to the Reef 2050 Plan.

The next Great Barrier Reef Outlook Report is due in mid-2024.

Read the Outlook Report 2019.

The Queensland government manage the Paddock to Reef Program (P2R). It is a framework for measuring progress towards meeting Reef 2050 Water Quality Improvement Plan targets.

The program is jointly funded by the Australian and Queensland governments and evaluates the adoption of land management practices and the effectiveness of these. It also assesses pollutant run-off as well as catchment and in-shore marine condition.

P2R also provides information and tools to prioritise investments. Investments activities are targeted, efficient and informed by the best expert advice.
