Fake Australian banknotes with Chinese characters across the currency's clear window have been found on a man detained for acting suspiciously in the South Australian regional town of Murray Bridge.
SA Police said the man was reported after being found with the "dodgy banknotes and a slingshot" after someone called in his suspicious activity on Monday night.
He was found with counterfeit notes in denominations of $100, $50 and $20.
Police said they believed similar notes were used to train bank staff and come from China.
"These notes are clearly distinguishable as fakes, as they have obvious Chinese characters across the clear window and dotted lines across the denomination," SA Police said.
"However, in dark or busy places or with distracted customers, it is possible they could pass temporarily as genuine."
A search of the 38-year-old's home, officers found a sling shot and a small quantity of cannabis.
The man was reported for unlawful possession and possession of a dangerous article and issued with a cannabis expiation notice.
He will appear in the Murray Bridge Magistrates Court at a later date.
