Aussies have been warned to check their cash after businesses at two tourist hotspots reported fake $50 notes to police.
The counterfeit notes were handed to shops in Merimbula and Eden on the NSW South Coast on Wednesday.
Both towns have had an influx of domestic and international visitors over the Christmas and New Year period.
NSW Police arrived to inspect the cash and found the transparent panel on the notes was faulty.
Officers are now trying to trace the source of the notes, a police spokesperson said.
It comes after police issued a separate warning in August over fake bank notes circulating in Tasmania.
Counterfeit $100 notes were found in Hobart and neighbouring suburbs Glenorchy and Bellerive.
But the notes had several key details that could be easily spotted, including a black plastic window, rather than a clear one.
