The three statuses
- Fluoride added: the utility doses fluoride into this supply, usually to 0.6 to 1.1 mg/L. We also use this for supplies officially dosed but running somewhat below target, and flag them.
- No fluoride added: nothing is added, either by decision or because dosing has stopped. Where a supply is officially fluoridated but measured levels show residents are effectively not receiving it (for example Broken Hill in 2026), we list it as no fluoride and explain why.
- Natural only: nothing is added, but the source water carries natural fluoride, sometimes at or above dosed levels.
We don't list towns as "unknown". We make a call on the best available evidence, link the source, and say in the note when that evidence is older or indirect.
Change flags
- Change coming: a start, stop or new plant has been decided or scheduled.
- Recently changed: a start, stop or restart since 2024. When a change is imminent and scheduled, we list the town at its new status.
- Dosing currently off: an officially fluoridated supply with an ongoing outage.
- Dosing below target: dosing is running but measured levels sit well below the state's target range.
Our sources, by state
- Queensland: Queensland Health's answers to Parliament listing councils without fluoride, council votes and notices, Seqwater monthly monitoring, and council water quality reports.
- New South Wales: NSW Health fluoridation committee minutes, council and utility water quality reports (including Sydney Water and Hunter Water), and council notices.
- Victoria: the Department of Health's "Is my water fluoridated" register and water corporations' annual drinking water quality reports.
- South Australia: SA Water's published water quality performance results and Hansard.
- Western Australia: WA Health's fluoridated towns list and Water Corporation's annual health data tables.
- Tasmania: the Tasmanian Economic Regulator's annual state of the industry report.
- Northern Territory and ACT: Power and Water and Icon Water information, and parliamentary answers.
Where official pages are inaccessible, we use parliamentary records, local news and archived documents, and never bypass website protections.
Measured levels
Where a utility publishes fluoride results, we show the figure and period on the town page and on our fluoride levels table. Levels vary by month and supply zone, so treat them as a guide and check your utility's latest report.
Keeping it current
Water supplies change: councils vote, plants break, new systems are commissioned. We recheck data regularly, log every reclassification on our updates and corrections page, and show each town's history on its page. If you know of a change, tell us.
What we don't do
We don't give medical or dental advice, and we don't take money from water utilities, health bodies, filter companies or campaign groups. See our editorial standards.
