The tell-tale sign these $50 notes circulating Aussie suburbs are fake

Australians have been warned to check their cash after businesses in two tourist hotspots reported counterfeit $50 notes to police.

The counterfeit notes were handed over to shops in Merimbula and Eden on the NSW south coast on Wednesday.

Both cities have had an influx of domestic and international visitors over the Christmas and New Year period.

NSW Police arrived to inspect the money and discovered the transparent panel on the notes was defective.

Officers are now trying to determine the source of the notes, a police spokesperson said.

It comes after police issued a separate warning in August about counterfeit banknotes circulating in Tasmania.

Counterfeit $100 notes were found in Hobart and the neighboring suburbs of Glenorchy and Bellerive.

But the notes had several important details that were easy to spot, including a black plastic window instead of a clear one.

How do you recognize a counterfeit banknote?

Feel the note – a real note is printed on a special plastic polymer and is difficult to tear.

Hold the note up to the light and look for the Australian coat of arms. This is usually located to the left of the clear window or denomination number when looking at the front of the note.

Look for slightly raised printing on the main design of the note.

Look for the seven-pointed star in a circle.

Compare the background prints – look for any distortions or less clearly defined patterns.

Check that the note has a clear window and a clear image: $50 has the Southern Cross and $100 has the lyrebird.

If possible, look under a UV lamp to find the serial numbers.
