SCAMMERS - when you answer, the call is a pre-recorded message saying that you "FEDERAL TAX ID" is suspended and you must press '1' before you are arrested. When you press 1, the person on the other end is clearly in India (you can hear everyone in the background has an Indian accent too, and the ATO call centre is Australian based, I've only ever spoken to people with Australian accents) and they will ask for your personal details like DOB & bank account. BEWARE!
