Impersonation Reports for 03 8000 4492

Four contributors have flagged calls from 03 8000 4492 (also written as 0380004492) for impersonation and suspicious behaviour. Three of these reports describe callers falsely claiming to represent major Australian financial and telecommunications companies, with attempts to extract personal and financial information. One additional report documents a silent call pattern from the same number.

The Victoria-based number allocated to Symbio Networks has been used to impersonate both Optus and Commonwealth Bank in separate incidents, suggesting either number spoofing or deliberate abuse of this service.

What Callers from 03 8000 4492 Claim

Contributors report callers from 03 8000 4492 making specific false claims depending on the impersonation attempt. One caller claimed to be an Optus representative checking internet IP settings on the recipient's phone, despite the recipient having no Optus account. This tactic created false urgency by suggesting a technical issue requiring immediate verification.

Two separate reports describe callers claiming to be from Commonwealth Bank enquiring about account activity and Bitcoin transactions. When recipients questioned or hesitated to provide information, the callers hung up within seconds. The rapid disconnection after being challenged suggests the caller recognised resistance and abandoned the call.

One contributor simply reported answering a call from 0380004492 only to have the caller hang up immediately without speaking, consistent with silent call or callback scam patterns.

Call Patterns and Timing

The four reports involving 03 8000 4492 span a three-week period from early to late January. Two Commonwealth Bank impersonation calls occurred on the same date (20 January) within three hours of each other, suggesting either repeated targeting or multiple scammers using the same compromised or spoofed number. The Optus impersonation occurred on 27 January, and the silent call on 8 January.

All answered calls were answered by the recipients themselves, indicating the number is actively dialling real people. The pattern of rapid hang-ups when challenged (Commonwealth Bank calls dropping after 10 seconds) suggests callers are using scripted approaches and abandoning calls when they encounter resistance.
