Caller: It was a text message not a call

This is one of the Aus Post text scams

This is the second time a text message from this number has advised me that an Australia Post parcel has been stalled because of an invalid address. It is tempting to click on the message but I didn’t and the parcel arrived by the due date with the correct address.
A colleague got his phone wrecked by malware that was downloaded by clicking on this type of message and the link included. I recommend that you understand that the official post number is 0448 008 003. Beware of any other number.
