Recent climate events such as extremely high temperatures and widespread drought have focused government and public attention on the effects of climate change in Australia. [8] Rainfall in southwestern Australia has decreased by 10–20% since the 1970s, while southeastern Australia has also experienced a moderate decline since the 1990s. [ 5 ]
Issues such as climate change and global warming are expected to impact the supply of water in Australia in the future, which can lead to severe consequences such as prolonged droughts. Historically, Australia's variable rainfall levels have caused the construction of various dams and reservoirs in major water systems, to ensure that a ...
However even if climate change does not result in decreased rainfall in eastern and northern Australia over the period to 2030, the perceived severity of drought (in terms of low soil moisture) would increase on account of the higher evaporative demand resulting from the projected overall rise in average temperatures.

The Department of Climate Change, Energy, the Environment and Water (DCCEEW) is a department of the Australian Government.The department was established on 1 July 2022, superseding the water and environment functions from the Department of Agriculture, Water and the Environment and energy functions from the Department of Industry, Science, Energy and Resources.
Water security in Australia became a major concern in Australia in the late 20th and early 21st century as a result of population growth, recurring severe droughts, effects of climate change on Australia, environmental degradation from reduced environmental flows, competition between competing interests such as grazing, irrigation and urban water supplies, and competition between upstream and ...
The report recognized climate change was of global significance and that Australia had an international obligation to address the problem. In 2000 the Senate Environment, Communications, Information Technology and the Arts References Committee conducted an inquiry that produced The Heat is On: Australia's Greenhouse Future .
