I have now received calls from 0416 037 911, 0416 037 990, 0416 037 994 and 0416 037 940 over the last 10 days. All they do is hang up after a few seconds. The worst thing is I share all but 2 digits with this phone number so I can't just tell people "ignore any calls in this number range". I'm worried I'll soon start getting abusive calls from people because some scammer is faking my legitimate number.
