The average quarterly water bill in Australia sits around $200-$250, varying by state, household size, and usage, with larger homes paying more and single-person households paying less, often billed quarterly with separate fixed service and usage charges. For instance, a single person might pay about $158 quarterly, while a larger family could pay over $270.
Australian households pay an average of $208 per quarter for water bills.
What is Average? The water industry estimates that an average person uses 3,000 gallons of water monthly, so a family of 4 would use 12,000 gallons for bathing, cooking, washing, recreation and watering.
A 20-minute shower can use 180 to 380 litres of water, depending on your showerhead: a water-efficient model uses about 180 litres (9 L/min), while an older, standard head can use up to 380 litres (19 L/min) or more. To calculate yours, multiply your showerhead's flow rate (in litres per minute) by 20.
The most common cause for a high water bill is running water from your toilet. A continuously running toilet can waste up to 200 gallons a day or more depending on the volume flow down the drain. This can cause a terrible increase to a family's typical water use, so fix toilet leaks as soon as possible.
“Are baths cheaper than showers?” This is all dependent on how much you fill your bathtub, how big it is, and how long you tend to shower for. A bathtub filled with 80 litres of water works out cheaper than a 10-minute shower using 100-150 litres of water.
On average, approximately 70 percent of that water is used indoors, with the bathroom being the largest consumer (a toilet alone can use 27 percent!).
Older style single flush toilets use 13 litres per flush. However, dual flush toilets use 6 litres for the full flush and 3 litres in the half flush.
Changing to a water meter may benefit you if you don't use much water. It may also be worth changing to a meter if your property has a high rateable value. This is because some water bills are based on the rateable value of the property.

Most high-efficiency washers use only 15 to 30 gallons (56.8 to 113.6 L) of water to wash the same amount of clothes as older washers (29 to 45 gallons per load (109.7 to 170 L). The most efficient washers use less than 5 gallons (18.9 L) per cubic foot of capacity.
Consistency: Pay attention to the consistency. Amniotic fluid is watery, while urine has a more typical liquid texture. Volume: Consider the amount of fluid. Amniotic fluid often trickles continuously, while urine leakage occurs in more discrete amounts.
A leaky toilet can be a massive contributor to a high water bill. We have seen continuously running toilets use 20,000 to 30,000 gallons of water in a month. A dripping leak consumes 15 gallons per day and 450 gallons per month. A 1/32 inch leak consumes 264 gallons per day and 7,920 gallons per month.
The typical cost for a professional water leak detection service in the UK ranges from £550 to £1,250.
