Overview

Wise management of wetlands is vital for protecting the Outstanding Universal Values of the Great Barrier Reef. As many wetlands are located on private property, it is a priority to work in partnership with landowners to achieve the best outcomes for everyone and the environment.

The Great Barrier Reef Outlook Report 2019, a five-yearly report, provides an overview of the condition of the Reef's ecosystem and heritage values, use, influencing factors, management effectiveness, resilience, and risks to its future.

The Reef Report Cards measure progress towards the Reef 2050 Water Quality Improvement Plan targets, objectives and long-term outcome. Additional information on the values and processes and extent of wetlands is also available.

The Wetlands of the Great Barrier Reef catchments brochure promotes the values of the wetlands. It outlines how wetlands are important for improving water quality, as habitat for fish and other wildlife, and for tourism and recreational opportunities.

The Great Barrier Reef—Our wetlands is a short two minute video that highlights the importance of wetlands in the catchments of the Great Barrier Reef. It features interviews with North Queenslanders who talk about how they value wetlands.

Wetlands and the Great Barrier Reef builds on the previous video—The Great Barrier Reef—Our wetlands. This 11 minute video explores the importance of wetlands in the Reef catchments more fully.

The Queensland Government Great Barrier Reef web site has information on the Reef, the World Heritage Area and priorities and plans.

The Reef 2050 Wetlands Strategy supports the Reef 2050 Long-Term Sustainability Plan 2021-25 and the Reef 2050 Water Quality Improvement Plan, setting out a framework for the improved management of the wetlands of the Great Barrier Reef catchments. It builds on the achievements of the Queensland Wetlands Program and recognises wetlands as vital to the health of the Great Barrier Reef ecosystem and its catchments.

This strategy includes five themes:

  • Improving wetlands information for decision making and action
  • Wetland planning
  • On-ground activities to protect, manage, rehabilitate and restore wetlands.
  • Engagement, education, communication and capacity building
  • Monitoring, evaluation, reporting and improvement

The development of an updated Reef 2050 Wetlands Strategy incorporated the outcomes of the independent evaluation of the of the 2016-21 Strategy and extensive consultation with Queensland State agencies, Australian Government agencies (DCCEEW, Reef Authority), GBR Wetlands Network, local governments, conservation organisations, Queensland Ports Association, agricultural and water supply representatives/peak bodies, and Traditional Owner representatives.

The Great Barrier Reef Marine Park Authority (the Reef Authority) release Position statements to express the Reef Authority's position on an issue where it has a strong interest, but outside it's direct regulatory control. These statements are based on the best available science and information. The Reef Authority has released a position statement for Coastal Ecosystems.

The 2017 Scientific Consensus Statement for the Great Barrier Reef is a review of scientific knowledge on water quality issues in the Great Barrier Reef. The statement was produced by a multidisciplinary group of scientists, with oversight from the Reef Independent Science Panel. It arrives at a consensus on the current understanding of the Great Barrier Reef system, and evaluates the ability of current initiatives to meet water quality targets set in the Reef 2050 Water Quality Improvement Plan 2017–2022.

A key theme of the statement is the importance of whole-of-catchment management. The complex interactions between wetlands and catchments and flow-on effects to the Great Barrier Reef are recognised throughout the statement. Chapter 1 contains an overview of the state of marine and coastal aquatic ecosystems and the pressures on them. Chapter 4 focuses on the role of wetlands, in terms of water quality, and the other ecosystem services they provide. A summary of the potential use and effectiveness of treatments systems is also provided.

The five-year Reef 2050 Water Quality Research, Development and Innovation Strategy 2017-2022 (RDI Strategy) is a joint action of the Queensland and Australian governments.

The Great Barrier Reef Priority Monitoring Gaps Prospectus (2021) provides an overview of the priority monitoring gaps that have been identified for investment over the next three years. The gaps have been prioritised based on their utility to assess progress against the Reef 2050 Plan and to inform management of the Reef.

The Reef Knowledge System enables resilience-based management of the Reef and its adjacent catchment, and provide managers with a comprehensive understanding of how the Reef 2050 Plan is progressing.

NESP Tropical Water Quality Hub Research Theme - Nutrients. Supports the Reef 2050 Water Quality Improvement Plan to reduce the delivery of nutrients from the catchment to the Great Barrier Reef (with a particular focus on nitrogen).

The Wetland Condition 2022 report details the wetland condition assessment methods plus the status and trend results for the 2022 reporting year, for the Great Barrier Reef catchment wetland condition monitoring program. The program tracks progress towards an objective of improved wetland condition, focussing on natural, freshwater floodplain wetlands in major aggregations within the Great Barrier Reef catchment area (GBRCA).

Disclaimer

Areas do not include marine or estuarine waters but do include estuarine wetland vegetation
(e.g. mangroves and tidal flats).

All statistics are approximate and generated based on data transformed to a customised Albers equal-area projection, thus allowing wetland extent change for different regions of Queensland to be comparable.

Areas may change over time as mapping approaches improve.

Totals may not match the sum of individually displayed figures due to the rounding of displayed figures.

Disclaimer

Areas do not include marine or estuarine waters but do include estuarine wetland vegetation
(e.g. mangroves and tidal flats).

All statistics are approximate and generated based on data transformed to a customised Albers equal-area projection, thus allowing wetland extent change for different regions of Queensland to be comparable.

Areas may change over time as mapping approaches improve.

Totals may not match the sum of individually displayed figures due to the rounding of displayed figures.
