australian tax office taking legal action against me, called back on contact number left but not connected.

It was a computer message telling me I'd been audited and ATO is now taking legal action against me for tax evasion.
What rubbish.

I keep them on the line for as long as possible. Makes me laugh,I lead
them on and tell them I had better get to the airport and leave the country.

Got a call from this number from an officer Michelle jones stating she was from the commonwealth director of public procecussion australian tax office telling me I have been audited for tax evasion and I owe $5000 and the call was being recorded and that if I hung up from the call they would start legal proceedings against me. She also asked if I was on Centrelink and she wanted me to pay it to an online bank transfer account.
I called ATO and this is a SCAM

Supposedly being audited for $1500. Trying to put the fear of the ATO into me.

It's a scam said she was from ato and if I didn't pay owing taxes with in 45 mins police would be at my house arresting me and when I asked when did this apparent fraud happen because I've always paid my taxes she couldn't answer
