Telstra Impersonation Scam Reports for 03 9003 4523

Two contributors have reported calls from 03 9003 4523 (also written as 0390034523) where the caller impersonated Telstra support staff. These are not legitimate service calls. In one report, the caller from 03 9003 4523 claimed there was an issue with internet in 'private mode' and attempted to direct the recipient to use Safari, a clear indicator of a phishing attempt. When challenged, the caller became abusive rather than professional, which is a red flag inconsistent with genuine Telstra support behaviour.

The second scam report about 0390034523 provides minimal detail but confirms the impersonation tactic. Both contributors correctly identified these calls as scams.

What Callers from 03 9003 4523 Claim

Callers from 03 9003 4523 specifically mention problems with internet connectivity in private mode and push recipients toward specific browser actions. One contributor reported the caller insisted they use Safari to resolve the supposed issue - this is a common phishing tactic designed to capture login credentials or install malware. When the recipient expressed suspicion, the caller responded with hostility ('called me stupid bitch'), abandoning any pretence of customer service.

Beyond the Telstra impersonation calls, 03 9003 4523 has also been used for energy company spam. A caller identifying himself as 'Max from Energy B company' rang about energy bills and called a second time despite being told the recipient has solar panels and doesn't pay bills. This suggests the number may be shared among multiple scammers and spammers, or the same operation runs various campaigns.

Call Patterns and Report Timeline

The reports span from mid-January to mid-February 2026. The two scam calls (impersonation and phishing) occurred on 9 and 15 February, suggesting recent intensified activity. One contributor answered a call from 03 9003 4523 while at work in early February and reported the caller became rude when told they were unavailable - not a characteristic of legitimate business calls. An earlier energy-related call on 13 January hung up immediately, then called back to pitch energy savers, indicating a pattern of persistence and call-back tactics used by this number.
