Repealed: Directory of Important Wetlands in Australia

The Directory of Important Wetlands in Australia (DIWA) dataset is held by the Climate Change, Energy, the Environment and Water (DCCEEW) web services and data repositories. This historical dataset is out of date and no longer updated. The data is spatially available as a layer on the Protected Matters Search Tool on the DCCEEW website.

It is a polygon coverage representing the wetlands cited in the "A Directory of Important Wetlands in Australia" Third Edition (EA, 2001), plus various additions for wetlands listed after 2001.

This coverage is a compilation of various data sources and has been collected using a variety of methods. This dataset was used as an indicative guide only to wetland boundaries and locations. The data has been collated by the Australian Government from various datasets including those supplied by the relevant State agencies.

State agency contributors include the Queensland Environmental Protection Authority, NSW Department of Environment and Conservation and the Victorian Department of Sustainability and Environment.

For the identification of wetland boundaries or locations in regard to the compliance of activities with relevant State legislation, the relevant State authority should be contacted to obtain the most recent and accurate wetland boundary information available.

The criteria for the definition of a wetland used in this dataset is that adopted by the Ramsar Convention, namely: "areas of marsh, fen, peatland or water, whether natural or artificial, permanent or temporary, with water that is static or flowing, fresh, brackish or salt, including areas of marine water the depth of which at low tide does not exceed six meters."
