Commonwealth Bank Impersonation Reports for 03 8000 4423
A contributor has reported receiving a call from 03 8000 4423 (also written as 0380004423) from a caller claiming to represent Commonwealth Bank. The impersonation occurred shortly after the recipient received a legitimate alert about a suspicious money transfer attempt on her account, suggesting the caller had knowledge of real account activity or recent security notifications.
The caller requested confirmation of personal banking details, exploiting the timing and urgency created by the genuine fraud alert. This pattern indicates deliberate coordination to manipulate victims into divulging sensitive information when they are already concerned about account security.
What the Caller from 03 8000 4423 Claimed
The caller on 0380004423 claimed affiliation with Commonwealth Bank and referenced the recipient's recent account activity, specifically mentioning knowledge of account balance and the attempted unauthorised transfer. By leveraging genuine security alerts already sent by the bank, the caller created false legitimacy and urgency, pressuring the recipient to "confirm her details" for supposed verification purposes.
This type of impersonation exploits a critical trust vulnerability: when customers receive legitimate fraud warnings, they are psychologically primed to cooperate with anyone claiming to help protect their accounts. The caller from 03 8000 4423 weaponised this natural response by appearing to reference real events.
Call Patterns and Timing
The call from 03 8000 4423 came through as a local Victorian service (allocated to Symbio Networks Pty Ltd), giving it surface legitimacy. The timing was deliberate: the caller contacted the recipient immediately after Commonwealth Bank's own security notification about the attempted money grab had arrived, maximising the psychological pressure on the victim.
This timing coordination suggests either advance knowledge of when the bank sends fraud alerts, or reactive opportunism exploiting widely-used fraud patterns. Either way, the caller from 0380004423 was counting on the recipient being in a heightened state of concern about account security.

WRITE A REVIEWFrequently Asked Questions
How did the caller from 03 8000 4423 know my account balance and recent fraud alert?
The caller may have accessed leaked banking data from a previous breach, purchased stolen account information, or used publicly available information combined with knowledge of common fraud patterns. Commonwealth Bank would never call asking you to confirm details after sending an alert - the bank already has this information. If you receive a call from 03 8000 4423 or similar claiming to verify account details, treat it as fraudulent. Always verify by calling the official bank number on your card.
Is 03 8000 4423 actually a Commonwealth Bank number?
No. The number 0380004423 is allocated to Symbio Networks Pty Ltd in Victoria, not Commonwealth Bank. Scammers can make calls appear to come from legitimate numbers (a technique called 'spoofing'), so never trust the caller ID alone. Commonwealth Bank's genuine customer service team will never ask you to confirm sensitive details over the phone. Always verify claims by calling Commonwealth Bank directly using the official number on your card.
What should I do if I already gave details to the caller from 03 8000 4423?
Contact Commonwealth Bank immediately using the number on the back of your card or their official website. Tell them which details you disclosed and request they review your account for fraud. Ask them to place a fraud alert on your account and monitor for unauthorised transactions. Change your online banking password and security questions. Monitor your account statements closely for the next few months. Report the incident to Scamwatch (scamwatch.gov.au) and provide as much detail as possible about the call from 0380004423.
Why do scammers call right after legitimate bank security alerts?
Scammers time their calls to exploit your anxiety. When you receive a real fraud alert from Commonwealth Bank, you're already worried and more likely to cooperate with anyone claiming to help. The caller from 03 8000 4423 knew this and used your legitimate security concern to pressure you into revealing details. This is why banks emphasise: we will never ask you to confirm sensitive information over an incoming call, regardless of timing or urgency.
Can I report this call to ACMA, and will they take action?
Yes, you can report the impersonation from 03 8000 4423 to ACMA via acma.gov.au. However, ACMA cannot directly retrieve money or reverse transfers. Your primary focus should be contacting Commonwealth Bank and your financial institution immediately. ACMA collects reports to identify patterns and pursue enforcement action against scam operations. Reporting 0380004423 helps build the evidence case and protects other Australians.
Should I block 03 8000 4423 or keep the number to report it?
Block 0380004423 immediately. Modern phones automatically record call logs, so blocking the number won't prevent you from reporting it - you already have the number recorded. Blocking 03 8000 4423 prevents the caller from contacting you again with follow-up attempts or variations. Report the number to Scamwatch and ACMA using the information you've documented, then block it for your own protection.
