ALARMED that the Government of New South Wales (NSW) is continuing to push ahead with processes designed to facilitate the raising of the Warragamba Dam, given its location within the Greater Blue Mountains World Heritage Area that would inundate over 1,000 hectares of the Greater Blue Mountains World Heritage Area and 3,700 hectares of the surrounding National Park, considered essential to the integrity of the property at the time of nomination;

CONCERNED that the NSW Government’s publicly stated intention is to raise the Warragamba Dam wall by 14 m, which will result in the regular flooding of 65 km of streams and rivers, home to eucalyptus forests and threatened species habitat;

CONCERNED that over 300 indigenous cultural sites would be inundated under the proposal to raise the Warragamba Dam wall;

AWARE that the Australian Government has stated that “The impact of increased flood water levels within the dam is likely to have extensive and significant impacts on listed threatened species and communities and world and national heritage values of the Greater Blue Mountains World Heritage Area”; and

CONCERNED that the cumulative impacts of coal mining within the Greater Blue Mountains World Heritage Area, notably water pollution and cliff collapse, are impacting upon the Outstanding Universal Values of the site;

The IUCN World Conservation Congress, at its session in Marseille, France:

1. CALLS ON the State Government of NSW to abandon all plans to raise the Warragamba Dam wall;

2. CALLS ON the Government of Australia to refuse all approvals for the raising of the Warragamba Dam wall and any other developments which would impact the Outstanding Universal Values of the Greater Blue Mountains World Heritage Area; and

3.ENCOURAGES the IUCN World Heritage Programme to continue to flag concerns regarding the Warragamba Dam-raising project, along with any other threats (post-NSW bushfires) to the Greater Blue Mountains World Heritage Area, through mechanisms such as World Heritage Outlook.

The Greater Blue Mountains World Heritage Area (GBMWHA) in Australia is at risk of being flooded by a proposal to raise the Warragamba Dam wall 14 metres for flood mitigation to enable downstream development on floodplains. The areas to be inundated (within the World Heritage Area) are of Outstanding Universal Value due to the eucalypt diversity of the region. The catchment is the most protected natural area in Australia, with six layers of state, federal and international protection afforded to it . The NSW Government Preliminary EIS stated there were 47 threatened species, including several species of eucalypt, that live within the areas that would be inundated by the proposal .

The New South Wales (provincial) Government passed an amendment to the National Parks and Wildlife Act (1974) to allow the flooding of the GBMWHA in October 2018 . IUCN identified this piece of legislation as central to the protection of the site its 2017 outlook report . Further to this, the IUCN World Heritage Outlook Report (2017) identified the raising of Warragamba Dam wall as being of “high threat inside the site.”

The NSW and Federal Government World Heritage Advisory Committee has stated: “the proposal will have significant adverse impacts on biodiversity, siltation and weed dispersal, wilderness and wild river values, Aboriginal cultural heritage values, aesthetic values and management access” of the site.

Over 300 Indigenous cultural heritage sites belonging to the Gundungurra people are located within the regions of the GBMWHA and will be inundated by the dam wall raising .

Given that a World Heritage Site will be impacted, the Australian Federal Government will have final consent over the dam wall raising. This consent is due to be decided upon in 2020. The New South Wales (provincial) Government has stated construction will commence in 2020 after the Environmental Impact Statement is completed .

International best practice floodplain development controls are not being applied in the Hawksbury-Nepean Valley. A comprehensive alternative flood management strategy for the downstream valleys has been compiled by respected Australian National University scientist Prof. Jamie Pittock .
