Caller ID (03) 4050 7564. Caller hangs up when phone answered. Google search indicates it is a landline telephone number and it could be in Balranald NSW or Mildura VIC / northern VIC. Have previously had "Hang up" calls like this then Scam Calls. They just check to see if you're home?

2nd time I’ve had a number call saying it was Annabranch NSW but a Victoria 03. No messages left

Automated call asking for me to answer questions in a poll about politics. I hung up before I had to listen to all the dribble.
