The feel-good factor from the Rugby World Cup has proven shortlived.
The ANZ-Roy Morgan consumer confidence index has fallen for the third month in a row, to its lowest level since May.
At 109 it's still above the neutral 100 level, indicating optimists still outnumber pessimists, but it's below the historical average of 118, said ANZ's head of market economics, Khoon Goh.
"This month's survey was taken after the [World Cup] final, so either the celebrations were short-lived and the hangover period has begun, or the ongoing uncertainty in the global economy is starting to put a dampener on things. We suspect it's more the latter."
The steepest fall was in perceptions of people's present financial position, from a 9 per cent negative last month to 18 per cent.
