Australia Post has warned customers of online scams as the postal service continues to struggle with unprecedented demand during the coronavirus pandemic.

A fraudulent email is circulating which prompts the recipients to click on a phishing link. The link leads to a fake Australia Post website, which requests personal and financial information.

“The email claims that your parcel was unable to be delivered and overweight, and asks for a payment to retrieve your package,” the company said.

A previous alert also warned customers against fake websites branded with the Post Billpay logo.

“Please note that Australia Post will never email or text message you asking for personal information, financial information or a payment.”

Australia Post advised customers who have sent any personal or financial information to a scam email address or website to call ID CARE on 1300 432 273.

The scam alerts came as Australia Post continues to deal with increased parcel volumes. In late April, the postal company said its parcel deliveries had doubled in the past month as online department store purchases rose 473 per cent.

Many Australians waiting for deliveries at home have seen their online orders delayed for weeks.

“We are doing everything possible to keep delivering during the Coronavirus pandemic,” Australia Post said on its website.

“The challenges presented by the pandemic mean there are delays as our business adopts additional safety measures to protect our people and customers.

“Other factors contributing to delays include fewer domestic flights, international delays and increased volumes as more people start shopping online.”
