"Scammers prey on busy lifestyles and the excitement and urgency in waiting for a package," Australia Post Chief Information Security Officer Adam Cartwright said.

"The safest way to track your deliveries is directly through the official AusPost app.

"If you're expecting a parcel, don't click on suspicious links or respond to unexpected messages — always check the app first."

AusPost said the latest scams are part of the "Darcula" phishing service operation.

The service allows scammers to rent a cybercrime toolkit that mimics well-trusted brands in order to steal customer data.

Darcula's techniques can bypass telecommunications and network scam filters, making them harder to block, according to AusPost.

Nine in 10 Australians have received a scam text or call.

Nearly three-quarters reported being the target of scams mimicking parcel delivery services.

Australia Post will never call, text or email you asking for personal or financial information, including password, credit card details or account information.

They will also never request payment from you over call, text or email.
