I called back number (02) 6985 8954 rang once then gets disconnected automatically.

Didn’t answer call as the number was not familiar. Believe it was a telemarketer

Automated answering service. Said they were an investigator on behalf on Department of home affairs

Overseas scammers "Government Solar Rebate" using a spoofed national number. Diverted to the scammer answering machine, I hope they enjoyed the chat with it.

I answered call, got the end of a garbled recorded massage and then nothing.
