Water restrictions have been enacted in many specific cities and regions in Australia, which is the Earth's driest inhabited continent, in response to chronic water shortages resulting from the widespread drought. Depending upon the location, these can include restrictions on watering lawns, using sprinkler systems, washing vehicles, hosing pavement, refilling swimming pools, etc. Overpopulation, evidence of drying climates, coupled with corresponding reductions in the supply of drinking water has led various state governments to consider alternative water sources to supplement existing sources, and to implement "water inspectors" who can issue penalties to those who waste water. Many states describe the different levels of water restrictions in terms of "stages": starting at Stage 1, for the least restrictive, going up as far as Stage 8. The highest level reached in the current drought has been stage 7 for Kingaroy. There are different definitions given to each "stage" in different states.
Water restrictions by state or territory Australia's national water consumption increased by 11.5% in 2023–24, reflecting higher irrigation demand and drier conditions. All mainland states have invested in large desalination plants to supplement rainfall-dependent water supplies. Melbourne's water storages experienced some of the lowest rainfall and inflows on record during 2024–25, similar to the worst years of the Millennium Drought, with inflows 36% below the 30-year average from July 2024 to June 2025. Permanent Water Saving Rules have applied across Victoria since 2011. The Bureau of Meteorology maintains a national Water Restrictions website providing current restriction information for the whole of Australia, searchable by state, territory and water agency.
Australian Capital Territory There are presently four stages of temporary water restrictions which can be imposed by ACTEW Corporation:
Canberra was subject to Stage 1 restrictions from 1 November 2005, which were increased to Stage 2 after a year on 1 November 2006. The continuing drought led to a further increase to Stage 3 from 16 December 2006; the restrictions were maintained at Stage 3 throughout 2007 and 2008. From 1 November 2010 Canberra moved to Permanent Water Saving Rules due to heavy rain bringing water storages close to capacity.
New South Wales The different classification levels of water restrictions in New South Wales vary widely, and are set by the different authorities responsible for water throughout the state.
Sydney The following levels have been used by Sydney Water to describe the different stages of water restrictions it has imposed. Level 3 Water Restriction Information is current as of 2009. Level 1 and Level 2 Water Restriction Information is current as of November 2019.
Sydney Water Restrictions (2019–present) Level 1 Restrictions: In late May 2019, it was announced that Sydney Water will be reinstating Level 1 water restrictions throughout the greater Sydney area. These restrictions began on 1 June 2019, as a result of an extremely dry year. As of 29 May 2019, Greater Sydney water supply levels are 53.4%, which is significantly lower than May 2018, in which supply levels were 73% in major catchments. Level 2 Restrictions: On 21 November 2019, the NSW government announced Level 2 water restrictions. These restrictions commenced on 10 December 2019, replacing the level 1 water restrictions. Level 2 restrictions have been brought in earlier than the Metropolitan Water Plan (2017) recommends, with dam levels currently at 46.1%. Premier Gladys Berejiklian, and Minister for Water, Property and Housing, Melinda Pavey announced the restrictions early as a precautionary measure, and to stave off the implementation of Level 3 restrictions later on. Level 3 Restrictions: Upon the commencement of the Level 2 water restrictions in December 2019, Minister for Water, Property and Housing, Melinda Pavey announced that Level 3 water restrictions should be expected early in the year of 2020. Sydney Water Restrictions (2003–2009) Falling dam levels prompted Sydney Water to impose Level 1 water restrictions on the Sydney area from 1 October 2003. When these restrictions failed to stem the reduction in the city's water supplies as a result of continuing drought, and with dam levels dropping below 50 per cent, Level 2 water restrictions were introduced from 1 June 2004. Further reductions in dam levels to below 40 per cent of capacity led to an increase to Level 3 water restrictions from 1 June 2005. Level 3 water restrictions were in place as of February 2008. Since June 2009, though, Sydney Water replaced water restrictions with Water Wise Rules. The Rules include:
All hoses must now have a trigger nozzle. Hand held hoses, sprinklers and watering systems may be used only before 10 am and after 4 pm on any day – to avoid the heat of the day. No hosing of hard surfaces such as paths and driveways. Washing vehicles is allowed. Fire hoses may be used for fire fighting activities only. To deal with its water shortage, New South Wales has followed the same path as Western Australia, in which a desalination plant for Sydney was built at an estimated cost of $1.3 billion. The Sydney Desalination Plant is to be turned on when Sydney's drinking water level reaches 60% capacity, and water restrictions will be in place when drinking water reaches 50% capacity. Sydney Water has imposed fines of $220 for violations of the rules for individuals, $550 for businesses, and $2,200 for water theft. Rules are enforced by Sydney Water staff through random checks.
Regional NSW As different towns in regional New South Wales take their drinking water from different sources, different levels of water restrictions apply. The levels or stages which apply in certain towns are as follows:
