Traditionally Consumer Confidence is calculated using a survey methodology, where 1,200 households in Australia are asked a series of questions. As you can imagine, this metric is only reported for the whole country (and sometimes per state).
I am afraid it is not possible to have Consumer Confidence reported for individual council area or suburb as it would mean performing the aforementioned survey monthly for hundred thousands of households.
Is your definition of Consumer Confidence different to the above?
Here is Consumer Confidence index produced by Westpac & Melbourne institute.
