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 16 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 April 2021. 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.
