Average Water Use and Cost In Australia.

Average Australian water and sewerage bills for 2011-2012.

Annual $ – Council area

Figures based on a three person household using 180 litres per person per day, equivalent to 200 kilolitres per year, and supplied by the Queensland Water Commission www.qwc.qld.gov.au

Average Australian daily residential water use (litres per person per day)
July 2010 to June 2011.

  • 163 Litres. All South East Queensland
  • 139 Litres. Central SEQ
  • 183 Litres. Gold Coast
  • 115 Litres. Scenic Rim
  • 172 Litres. Redland
  • 179 Litres. Sunshine Coast



Australian Water Costs vary by each state and /or water authority.

An Example of Water Prices in 2016-17, for the ACT.

$101.48 Annual Fixed Fee for Water Supply
$529.38 Annual Fixed Fee for Sewerage
$ 2.61 per kL for the first 548 litres per day
$ 5.24 per kL for the excess over 548 litres per day

This, when calculated for a family using 500 litres per day, would be: $1,107 per year
or, if using 900 litres per day would be: $1,721 per year

A similar charge for one of the Queensland water suppliers would be:

500 litres per day would be: $ 859 per year
900 litres per day would be: $1,455 per year

Confusion can arise when looking at the Queensland water charges as a local authority water supply charge may be quoted as:
Up to 74kL per quarter $0.26 per kL

That is substantially lower than the $2.61 per kL quoted by the first example from the ACT.
However, the QLD state governent make a seperate charge of over $2 per kL
