Some dodgy "you have overseas warrants" scam. Comes in as an overseas call, but asks to ring back on this number

Be assured that the Australian Taxation will never call, this number is a scam, tell them that this call is being recorded and you are passing it onto the police department who have the facility to trace the call, you watch how quick they will hang up. It is coming from overseas and they seem to target elderly people.

Officer Ron Wilson from Australian Tax Office wants me to call in regards to some unusual activity in my tax return. If I don't call back I will have some legal problems. Asks me to call back on this number.
