Automatic message said they were calling from dept of home affairs.

In a fake government threat scam, victims receive a robocall pretending to be from a government department, such as the ATO or Department of Home Affairs.

The scammer will claim something illegal, such as tax fraud or money laundering, has been committed in the victim’s name and they should dial 1 to speak to an operator.

The scammer then tries to scare people into handing over money and may threaten that they would be arrested if they refuse.

“Don’t be pressured by a threatening caller and take your time to consider who you might be dealing with,” Ms Rickard said.

“Government departments will never threaten you with immediate arrest or ask for payment by unusual methods such as gift cards, iTunes vouches or bank transfers.”
