What are the major political parties position on the issue?

Answer

The NSW Liberal Government are the proponents of the dam wall raising. The NSW Labor Party and the NSW Greens have been vocal in their opposition to the proposal, voting against the Water NSW Amendment (2018) Bill that was passed by the NSW Parliament to allow the flooding of national parks resulting from the dam wall raising. NSW Labor Shadow Water Spokesperson, Chris Minns, has said the dam wall raising would not proceed if NSW Labor were elected to government. Neither major parties at a federal level have stated a position on the proposal.
