Suspicious Activity from 0402 594 174

A single contributor has reported suspicious behaviour from 0402 594 174 (also written as 0402594174), an Optus mobile number. The caller disconnected immediately when the call was answered, before any conversation could occur. The contributor noted this pattern repeats across multiple numbers, suggesting a systematic approach rather than a misdial.

What This Call Pattern Indicates

Immediate hang-ups upon answer are characteristic of callback scams or number verification campaigns. Scammers use this tactic to identify active phone numbers and willing answerers for follow-up contact. By calling and disconnecting when someone picks up, they confirm the number is in use and monitored by a real person. The contributor's observation that 0402594174 is part of a broader pattern of similar calls from different numbers reinforces this assessment.

Protecting Yourself from Callback Scams

Callback scam operators purchase or generate lists of phone numbers and call in bulk, hanging up when answered. This tests which numbers are active. Days or weeks later, they call back with a scam pitch (fake tax debt, parcel delivery, tech support issue). Because they know you answered before, they have higher confidence you'll engage. The best defence is to never return unknown calls, block numbers immediately, and ignore any follow-up contact from 0402594174 or similar sources.
