Thanks Jason
I also found this from the Council Reference Group (CRG) meeting 12 August 2025
• Dam safety levy: An update on the Dam Safety Levy was presented following discussion at CRG meeting 2. CRG members discussed the Dam Safety Levy and its impact.
o Preliminary estimates show that 27 councils are affected, with the potential adjustment factor to the rate peg ranging from 0.01% to 0.52% (only 2 councils more than 0.1%, 18 councils were less than 0.1%).
o The estimates have been isolated so that dams which provide drinking water are not targeted as the costs for these dams can be recovered through water charges. Dams which are for other purposes, such as retention basins are included. LGNSW noted that they will provide oversight to confirm that IPART has correctly classified dams.
