Water pricing and average household bills in five Australian cities

The table illustrates the pricing structures for water consumption and the resulting average household bills across five major Australian cities. Overall, the data reveals a clear divide between cities with uniform pricing and those that implement tiered rates based on consumption levels.

Sydney and Melbourne maintain a flat rate for all water usage, charging $0.98 and $0.78 per kiloliter respectively. In contrast, Adelaide, Brisbane, and Perth apply tiered pricing. Perth exhibits the most significant price jump, increasing from $0.42 for usage up to 125 KL to $1.50 for consumption exceeding that threshold. Adelaide follows a similar, albeit less extreme, pattern, rising from $0.42 to $1.00. Brisbane shows the most modest increase, moving from $0.81 to $0.84.

Regarding average household expenditure, Perth residents pay the most at $332, despite the city's low initial usage rate. Sydney and Adelaide follow with bills of $319 and $312, respectively. Brisbane’s average bill is slightly lower at $310. Melbourne, which benefits from the lowest flat rate of $0.78 per kiloliter, also records the lowest average household bill among the five cities, at $253.
