Data confidence level: 
Desalination plants began to pop up in Australia during the 1997-2009 drought as a way to bolster water supply. In this process, seawater is taken and purified by using reverse osmosis technology. This FACT indicates the amount in megalitres of state water supply sourced from a desalination process per 100,000 persons in each Australian state. For the data expressed here, a lack of a data entry is likely to indicate that there are not currently any desalination plants operating in these states or territories.
