This is scam, just hang up and report to ATO.

This is a scam. They are pretending they are from the Australian Taxation Office and that they have conducted an audit on you and that you owe money. Be very careful. Do not give out any personal detail and definately not your credit card details.

This is a recorded message supposedly from the Aust Tax Office. Unfortunately I rejected it before finding out what the scam was.

This is a tax scam... be careful
