Who wants to raise the Warragamba Dam wall?

Answer

Housing developers. While the dam wall raising was proposed in 2016 by the Baird (NSW Liberal) Government, it is land developers on the Hawkesbury-Nepean floodplain who seek to benefit for the dam wall raising. The NSW Government has itself stated that it plans to allow developers to place and additional 134,000 people on the floodplain once the dam wall is raised - doubling the existing floodplain population.
