The Westpac Consumer Confidence Change tracks the monthly % change in the Westpac-Melbourne Institute Index of Consumer Sentiment. It is published jointly by Westpac Banking Corporation and the Melbourne Institute of Applied Economic and Social Research at the University of Melbourne. It is based on a private monthly survey running since March 1973 across Australia, not an Australian Bureau of Statistics release. It captures household views and expectations on money, economy and buying time, not actual spending, retail sales or business sentiment.
