The table illustrates the cost of water usage up to and over 125KL in five Australian cities, as well as the average household bill. Overall, it would appear from the data that the cost for usage over 125KL is higher than that for lower usage in all the given cities, except for Melbourne and Sydney. In addition, Perth has the highest average household bill of the five cities.
To begin, it can be observed that Perth has the highest charge for usage over 125KL at $1.50, while the figure for usage up to 125KL is the lowest at $0.42. Similarly, in Adelaide, $1.00 is recorded over 125KL, whereas the figure for usage up to 125KL is the same figure as that in Perth. Likewise, in Brisbane people spend $0.84 in usage over 125KL on average, which is $0.03 higher than that up to 125KL. In contrast, the figure for usage up to 125KL and over 125KL in Melbourne and Sydney is the same at $0.78 and $0.98, respectively.
Turing to the average household bill, Perth ranks highest again at $332. The figures for Brisbane, Adelaide and Sydney range between $310 and $319. Finally, the smallest number is recorded in Melbourne at $253.
