Numbers Picking Up Reports Quickly
10 numbers in VIC picked up multiple reports in a short period this month, which typically indicates active call campaigns.
Flagged numbers averaged 9 reports each, meaning multiple people encountered them independently.
Reports on these numbers came from multiple areas across VIC, which points to automated dialling rather than calls targeting a single region.
Mixed Classifications
Some numbers got both scam and non-scam reports during December 2022. This can happen when a legitimate number is being spoofed, when a business number starts getting used for something else, or when people simply aren't sure what the call was about. These are worth keeping an eye on.

Safety Tips
- Don't call back unknown 03 numbers without checking them first.
- The ATO, Centrelink, and Medicare won't threaten you over the phone. If someone claims to be from a government agency, hang up and call the official number yourself.
- Don't tap payment or delivery links in texts from numbers you don't recognise.
- Got a suspicious call? Report it - every report helps other people in Victoria.
- Look up numbers on Reverseau before calling back.
