Australia 'among nations with cleanest money'

Australia's bank notes may be among the world's cleanest, according to a new study.

Researchers led by the University of Ballarat's food microbiologist Frank Vriesekoop analysed bank notes from at least ten nations across the world including Australia, China, Ireland, Mexico, Netherlands, New Zealand, Britain and the US.

The findings served to undermine the popular belief that money can be a haven for germs.

"Nowhere in the world were alarming levels of pathogenic bacteria found," said Mr Vriesekoop.

The analysis also revealed that richer, more developed countries tend to have the cleanest bank notes while older money tends to be dirtier.

Meanwhile, the researchers discovered that polymer notes used by countries like Australia are less welcoming to bacteria thanks to their harder-wearing and smooth surface.

The news may interest consumers looking to compare credit cards in search of cash-free spending options. According to an editorial on last week, Australian consumers can avoid losing out in currency exchanges by making use of special travel debit cards.
