Australia has a variety of water sources, including rivers, streams, reservoirs, and groundwater, which provide drinking water for its states. The quality of water can vary due to environmental and human factors, and each state has unique challenges in ensuring clean water for its residents. While personal preferences and perceptions may influence the perception of water taste, some states and cities are consistently recognised for their water quality. Tasmania, for example, has been praised for its clean water, with TasWater winning awards for its excellent drinking water. Other cities like Melbourne and Hobart are also known for their good-tasting tap water, while Adelaide and Perth have been criticised for their salty or poorly tasting water. Water quality is a critical aspect of public health and environmental sustainability, and Australia continues to invest in sustainable water sources and treatment processes to improve access to clean water nationwide.

What You'll Learn
Tasmania has the cleanest water
Tasmania's clean water is the result of continued investment and effort by the state government and TasWater. In 2012, TasWater conducted a statewide benchmarking review and identified areas that needed improvement. This led to the launch of the 24glasses Regional Towns Water Supply Program, which aimed to improve drinking water quality across the state. Since then, TasWater has invested heavily in water treatment, spending nearly $120 million in 2021 alone.
Tasmania's water is also naturally cleaner than that of mainland Australia. Leon Barmuta, a freshwater ecologist at the University of Tasmania, notes that most of Australia's surface freshwater is dominated by sodium and chloride ions due to wind-blown salt from the ocean. However, Tasmania's water sources are less affected by these factors, resulting in cleaner and better-tasting water.
In contrast, other Australian states face challenges in providing clean water. For example, Adelaide's water sources are at the end of the Murray River, where water picks up various contaminants. Perth, meanwhile, relies on groundwater due to drought conditions, which generally has a higher salt content.
Overall, Tasmania's clean water is a result of both natural factors and the dedicated efforts of the state government and water authorities. Through continued investment and a focus on quality, Tasmania has earned its reputation for having the cleanest water in Australia.

Melbourne has the best water
While opinions vary on which Australian state has the cleanest water, Melbourne is certainly a strong contender for this title. In fact, Melbourne tap water is widely regarded as some of the highest-quality drinking water in the world. It is safe to drink and complies with Australian drinking water guidelines and strict water quality standards.
Melbourne's water is sourced from protected catchments in the Yarra Ranges, where native forests act as a natural filter. The city's water supply is regularly tested at multiple points to ensure that it meets these high standards, and Melbourne is one of only two cities globally that sources its water from such protected sources.
The high quality of Melbourne's tap water has been recognised internationally. In 2016 and 2019, it was awarded second place in the 'Best Municipal Water' category at the International Water Tasting Competition. In the 2018 Australian National Finals hosted in Toowoomba, the water sample from Wannon Water in Victoria took out top honours, with over 150 votes.
Melbourne's water quality is so exceptional that it even tastes good. While taste preferences may vary, many people find the water pleasant to drink, and it has been described as some of the best-tasting tap water in Australia. This is likely due to the natural filtration provided by the Yarra Ranges' native forests, resulting in water that is not only safe but also enjoyable to consume.
In summary, Melbourne's tap water is of exceptionally high quality and is widely considered one of the best in Australia, if not the world. The city's commitment to providing safe and delicious drinking water is evident through its sourcing, treatment, and rigorous testing practices, ensuring that residents and visitors alike can confidently enjoy a glass of Melbourne's finest.

Adelaide has the saltiest water
While there is no clear consensus on which state in Australia has the cleanest water, Adelaide's water has a terrible reputation. Adelaide has been described as having the saltiest water, along with Perth and Brisbane. The high salinity in Adelaide's water is likely due to its geographical location at the end of a long river that passes through thousands of farms and towns in three states before reaching the city. The water from the Murray River, Adelaide's main water source, is shared with New South Wales and Victoria, making it difficult for South Australia to control water quality.
The taste of Adelaide's water has been described as unpleasant, with reports of a strong chlorine smell and a metallic taste. Some residents of Adelaide have resorted to installing water filters in their homes to improve the taste and quality of their water.
In contrast, Melbourne's water is considered superior due to its natural filtration through protected catchments, resulting in less treatment being required. Melbourne's water has won awards for its taste, and the city has represented Victoria in national water taste competitions.
Water salinity is an important consideration for individuals on low-sodium diets, as high sodium levels in drinking water can have health implications. It is recommended that individuals on low-sodium diets drink water with less than 20 mg of sodium per litre. However, Adelaide's water supply contains more than this recommended amount, with some areas in Perth having even higher sodium levels.
While Adelaide's water may have a poor reputation, it is important to note that water quality can vary within states and that infrastructure and plumbing can also impact the taste and safety of drinking water.

Water quality issues vary across states
For instance, Adelaide, South Australia, has long been reputed to have some of the worst-tasting tap water in the country due to its position at the end of the Murray River. Water from the Murray River travels long distances and picks up various organic and inorganic contaminants, requiring higher chlorine levels for treatment. Similarly, Queensland's water has been described as more turbid than that of other states, with a more earthy and muddied quality, due to its reliance on surface reservoirs and groundwater sources.
In contrast, Melbourne, Darwin, Canberra, and Hobart have been noted for having less salty water. Tasmania, in particular, is known for its clean water, with the state's water authority winning awards for best-tasting tap water. This can be attributed to the state's abundant lakes and rivers, as well as the implementation of water treatment systems to address quality concerns.
Water quality can also be influenced by factors such as agricultural runoff, vegetation, animal activity, and household fittings. For example, older buildings in cities like Melbourne and Sydney may use lead or copper pipes, which can impact the taste and safety of drinking water. Additionally, the taste of water is subjective and can vary depending on individual sensitivity to changes in chemical balances.
While some states may face unique challenges, it is important to note that water quality issues are not limited to specific regions and can vary within states as well. Water authorities across Australia continuously work to improve water quality and ensure safe and reliable drinking water for their residents.

Water filtration improves taste and quality
While opinions vary on which Australian state has the cleanest water, there is consensus that Adelaide has the worst-tasting tap water. One resident describes the water as tasting like "hard metals and a dash of chlorine." Another comments that the water in older buildings in Melbourne and Sydney might be safer but "taste great."
Filtered water often emerges as the preferred choice due to its cleaner, purer taste profile. By removing impurities and additives, filtration systems enhance the clarity, freshness, and overall palatability of the water. The extent to which individuals perceive a difference in taste can depend on various factors, including the quality of their tap water and the effectiveness of their chosen filtration method.
Water filtration systems employ different mechanisms to eliminate impurities. For example, activated carbon filters, which can be installed under the kitchen sink or mounted on a wall, absorb chemicals like chlorine, while reverse osmosis systems use a semi-permeable membrane to remove microscopic particles, ensuring the final note is crystal clear and free from impurities.
In addition to improving taste, water filtration systems also offer health benefits by removing contaminants and impurities that may be harmful to health.
