Australia Post has issued a warning ahead of the busy Christmas delivery period about a text scam targeting its customers.

Scam victim Jess Watt said she opened the SMS link because her phone said the text came from “AusPost”.

“They didn’t only have my name and phone number because they had my full address, which really concerned me because that coincided with the delivery of my package.”

The text message reads “The results are in, and your address has been drawn”.

Victims say the link leads to malware which then locks the device and demands a fee to unlock it.

“It looks so real but they’re not and they will catch you off guard when you least expect it,” Fair Trading spokesperson Michelle Jamena said.

In its warning, Australia Post described the texts as “fraudulent SMSs” and insisted it never asks for or gives out personal information.

The ACCC and police have warned Christmas is a peak time for scammers.
