Beware of this scam! The recorded message (sounding authoritative) claimed to be from the ATO, regarding an unpaid taxation debt, threatening jail if unpaid. The prompt was to press "1" to continue. Funny thing was that I'd just been on the phone to the ATO, for assistance with a BAS return. What a load of ****, please don't answer this scammer.

Same voice message as Chrissy says. Ignore.
