Northern Territory Police advise retailers and the public to watch for counterfeit $50 and $100 notes following the seizures of more than $20,000 in fake currency since September 2025.

These recent seizures follow an increase in attempted importation, possession, and use of counterfeit notes at businesses across the Northern Territory.

Police note that the counterfeit notes are of “reasonable quality,” but can be identified by the word “COPY” printed in small text on one side and the texture is paper based not polymer.  

Detective Senior Sergeant Corey Borton said "Individuals using these notes often make small purchases and pass them as legitimate currency or conceal them among genuine notes during larger transactions.

"Northern Territory Police urge all retailers to stay alert. If you think a note is fake and it is safe to do so, do not accept it.

"Police recommend that if you believe you have received counterfeit money, put it in an envelope, record how it came into your possession, and call police on 131 444.

"Alternatively, if you know someone in possession of counterfeit currency, you can make an anonymous report to police via Crime Stoppers on 1800 333 000."

Offences relating to the making, importing, buying, selling, possessing, or using counterfeit Australian currency are indictable offences under the Crimes (Currency) Act 1981 and carry maximum penalties of up to 14 years imprisonment.

More information on detecting counterfeit money is available on the Reserve Bank of Australia website.
