The objective of the Australian and New Zealand Guidelines for Fresh and Marine Water Quality is to provide authoritative guidance on the management of water quality in Australia and New Zealand. Our guidance includes setting water quality and sediment quality objectives designed to sustain current, or likely future, community values for natural and semi-natural water resources.
The Water Quality Guidelines provide:
- a platform for consistent water quality management and planning
- technical support for Australia’s National Water Quality Management Strategy and New Zealand’s National Policy Statement for Freshwater Management
- sound tools for governments and the community to assess and manage ambient water and sediment quality.
The main focus of the Water Quality Guidelines is on water quality within the context of broader ecosystem health management.
Information in the Water Quality Guidelines:
- may be applicable to natural and seminatural waters in Australia and New Zealand, including freshwater, groundwater and estuarine and marine waters
- will support different
community values of water, such as aquatic ecosystems, drinking water, primary industries, recreation, and cultural and spiritual values.
The Water Quality Guidelines are not intended to directly apply to contaminant concentrations in industrial discharges or stormwater quality (unless stormwater systems are regarded as having relevant community value).
Topics in the Water Quality Guidelines cover:
The Water Quality Guidelines are a joint initiative of the Australian and New Zealand governments, in partnership with the Australian states and territories. Although there is a joint governance structure for the Water Quality Guidelines, the management context and jurisdictional responsibilities differ between Australia and New Zealand.
Oversight of the Water Quality Guidelines is the responsibility of the Water Quality Policy Sub Committee (WQPSC) and National Water Reform Committee (NWRC).
The revision of the ANZECC & ARMCANZ (2000) guidelines was managed by 4 groups responsible for different levels of governance of this project:
- Project Coordination Group (PCG) — scientific members from relevant government agencies who managed technical aspects of the revision and content in the Water Quality Guidelines.
- Joint Steering Committee (JSC) — jurisdictional representatives who provided strategic direction, managed approved work plans and provided high level technical input supported by the PCG.
WQPSC and NWRC, which sit above the JSC.
Australian context and jurisdictional responsibilities
National Water Quality Management Strategy is designed to facilitate water quality management for the productive and sustainable use of Australia’s water resources and to protect aquatic ecosystems.
The National Water Quality Management Strategy framework, including the Water Quality Guidelines, is voluntary, and different jurisdictions in Australia have different responsibilities.
The Australian Government is responsible for:
Australian state and territory governments hold most of the responsibility for management of inland waters and coastal natural resources. Implementation of the Water Quality Guidelines occurs through their relevant water quality planning and management policy processes.
Complementary planning may occur at a regional or catchment level, with local or catchment management strategies developed and implemented by relevant stakeholders. This could include local governments and catchment management bodies.
New Zealand context and jurisdictional responsibilities
Primary responsibility for water management rests with the
regional councils in New Zealand.
National Policy Statement for Freshwater Management provides a framework that directs how local councils go about managing freshwater quality under the
Resource Management Act 1991. This includes nationally set minimum acceptable standards for water quality for the ‘ecosystem health’ and ‘human health for recreation’ community values of waterways.
New Zealand Coastal Policy Statement guides local councils in their management of the coastal environment under the Resources Management Act.
As with previous revisions,
developing the Water Quality Guidelines was challenging and complex. A large amount of content had to be drafted or updated, and then translated to an online platform.
The Water Quality Guidelines website has been made possible with substantial assistance from many people and organisations across Australia and New Zealand, from 2009 to 2018.
Management of the website development was undertaken by Dr Angela Slade from the Australian Government Department of Agriculture and Water Resources (and formerly New Zealand Ministry for the Environment). Technical coordination of the revision was shared by Dr Rick van Dam and Dr Chris Humphrey from the Environmental Research Institute of the Supervising Scientist (ERISS), within the Australian Government Department of the Environment and Energy.
PCG–Web Subgroup members, John Bennett from Queensland Department of the Environment and Heritage Protection (now Department of Environment and Science), Dr Chris Humphrey, Dr Angela Slade and Dr Rick van Dam, developed the website information architecture, and contributed, reviewed and edited content for all website sections.
Australian governments and the New Zealand Government would like to acknowledge the contributions from the following organisations and individuals, by website section.
Hydrobiology (led by Dr Ross Smith) for drafting initial content.
Water Quality Management Framework section
Hydrobiology (led by Dr Ross Smith) for drafting initial content.
ARRIS for updates to primary industries content; CSIRO (led by Dr Merrin Adams) for toxicant default guideline value (DGV) derivations; Golder Associates (led by Drs Kirsten Broadgate and Carolyn Brumley) for toxicant DGV derivations; Hydrobiology (led by Drs Ross Smith and Graeme Batley, CSIRO) for drafting initial content for subsections; Jacobs (led by Dr Celeste Wilson) for toxicant DGV derivations; NIWA (led by Dr Chris Hickey) for toxicant DGV derivations; and Natural Resource Assessment (led by Alicia Hogan) for managing the technical review of new and revised toxicant DGVs. Development of Burrlioz 2.0 software was led by Dr Simon Barry. Development of the cultural and spiritual values content was led by Roku Mihinui and Bradley Moggridge. Development of the toxicant DGV derivation methodology was led by Dr Michael Warne.

Contributions were provided throughout the revision project by members of the PCG from Australia and New Zealand, in particular: John Bennett, Monika Muschal (New South Wales Department of Primary Industries), Dr Evan Harrison (New Zealand Ministry for the Environment), Dr Chris Hepplewhite (Department of Agriculture and Water Resources), Dr Chris Humphrey, Dr Clive Jenkins (Environment Protection Authority, South Australia), Kevin McAlpine (Western Australian Environmental Protection Authority), Leon Metzeling (Environment Protection Authority, Victoria), Dr Angela Slade and Dr Rick van Dam, Chair.
We would like to give particular thanks to the water quality experts from the working groups in Phase 1 of the revision of the Water Quality Guidelines.
The Department of Agriculture and Water Resources provided secretariat, project, copyediting, legal and communications support.
We would also like to acknowledge the contributions of the web writer (Tristan Viscarra Rossel), website designer (Thomas Buckland) and website developer (Mehmood Rehman).
Many other organisations and individuals contributed to the review and, although they are too numerous to list here, we would like to thank them all.
