Water fluoridation

Approximately 72% of Queenslanders receive fluoridated drinking water.

Legislation and regulation

Fluoridation in Queensland is regulated under the Water Fluoridation Act 2008 and Water Fluoridation Regulation 2020.

Under the Water Fluoridation Act 2008 each local government in Queensland is able to make the decision whether or not the town water supplies within their area are fluoridated.

Where there is a single water supplier for multiple local government areas (e.g. in South East Queensland), each individual local government must take account of the impact of their decision on other local governments serviced by that water supplier.

Safe operation of water fluoridation infrastructure

The design and operation of infrastructure for adding fluoride to drinking water supplies is described in the Queensland Water Fluoridation Code of Practice (PDF 752 kB). The Water Fluoridation Regulation 2020 and the Code of Practice include a wide range of safeguards to ensure that fluoride is safely added to water supplies.

The amount of fluoride that can be added to drinking water in Queensland is set in the Water Fluoridation Regulation 2020 and ranges from 0.6 parts per million (ppm) to 0.8 ppm, depending on location. This is equivalent to less than one drop of fluoride diluted into 50 litres of water.


The amount of fluoride added to water supplies in Queensland must be checked daily by the water supplier and reported to the Department of Health on a regular basis.
