Caller: They say legal dept of Services Australia

Got a call from this number, first was a recorded message saying that they have detected suspicious activity in my bank account therefore my taxfile and banking services have been suspended. They then instructed me to press 1, which put me through to an Indian man answering 'welcome to legal team of Services Australia, how can I help you?'
I said I got a call and was put through to you. They then hung up... not sure what to make of it
