Consumer confidence in eurozone nations varied widely, with 78 per cent in Spain, 73 per cent in Italy and 69 per cent in France reporting they were personally affected.
However, this dropped to 35 per cent in Germany.
Goth said concerns of local consumers were much higher than a year ago when Australia was included in BCG's global survey for the first time.
The survey found that 50 per cent of Australians intended to spend less on discretionary items, compared to 47 per cent last year.
This was more than US consumers, at 46 per cent, and the same as European Union consumers, on 50 per cent.
Surprisingly, a similar percentage of Australians, 22 per cent, felt insecure about their job in the current year as Americans, 23 per cent, French, 22 per cent, and Germans, 25 per cent.
The BCG's 11th annual Consumer Sentiment Survey was conducted in April among 15,000 consumers in 16 countries.
