Please note: The below billing calculators reflect 2025-26 water pricing. We are currently working to include pricing notes for 2025-26. Please be advised that there is a delay to the 2025 Water Administration Ministerial Corporation (WAMC) determination until 1 October 2025. As such 2024-25 WAMC pricing will remain in place until 30 September 2025 and is subject to change 1 October 2025.
As a result, the calculators provide the best available estimate for your total charges across the 2025-26 financial year.
