Survey questions used in the nationally representative questionnaire were derived from insights gained
during the qualitative study phase. The survey included questions about: 1) attitudes to water
conservation; 2) water conservation practices; 3) water efficient appliances, and 4) barriers to the
purchase of water efficient appliances. Due to the qualitative study previously conducted, it was
possible to formulate all these questions as forced choice binary questions (yes / no, or agree / disagree)
rather than open-ended questions. The advantage of this two-step approach is that (1) the qualitative
phase ensured that all critical answer options were included, and (2) the simple survey format ensured
that valid quantitative information could be obtained from a representative sample of Australians.
Details on the questions are provided in the results and discussion section.
