As the country's supply of freshwater is increasingly vulnerable to droughts as a result of climate change, there is an emphasis on water conservation and various regions have imposed restrictions on the use of water. In 2006, Perth became the first Australian city to operate a reverse osmosis seawater desalination plant, the Kwinana Desalination Plant, to reduce the city's vulnerability to droughts. More plants are planned or are under construction in Sydney, the Gold Coast, Melbourne, and Adelaide. The use of reclaimed water is also increasingly common.
