Telstra Impersonation Reports for 03 9003 4524

Two contributors have reported scam calls from 03 9003 4524 (also written as 0390034524) where callers impersonate Telstra customer service. The pattern is consistent across reports: the caller claims to have detected an internet security or connectivity problem, creates a sense of urgency, and attempts to extract sensitive information. One contributor noted the caller specifically asked them to locate their ISP number and read it aloud, a classic tactic for collecting account details that could be used for fraud or unauthorised access.

The impersonation is deliberate and targeted. Callers from 0390034524 reference real Telstra services and technical language to establish credibility, making the scam more convincing to recipients unfamiliar with how Telstra actually communicates about account issues.

What Callers from 03 9003 4524 Claim

Contributors describe callers from 03 9003 4524 claiming the recipient's internet connection is vulnerable or publicly accessible. One report states the caller said the internet was "on public" and needed immediate fixing. Another describes being told a general internet issue had been detected. In both cases, the caller then attempted to move the conversation toward obtaining sensitive account information.

The requests are specific: callers ask you to find your ISP number and read it out. This information, combined with other details often already in the caller's possession, can be used to impersonate you when contacting your actual internet service provider. The urgency messaging (problems need fixing now, security risk) is designed to bypass normal caution and push quick compliance.

Report Patterns and Timing

The two confirmed scam reports involving 0390034524 came within weeks of each other (early and mid-February 2026), suggesting an active campaign. One call was answered and engaged with briefly, while another report indicates the caller persisted despite the recipient's hesitation. A third report from the same period shows 03 9003 4524 calling without leaving a message, consistent with scam operations that dial multiple numbers in sequence.

Contributors who answered reported an immediate sense that the call was fraudulent, describing the tone and approach as characteristic of a scam rather than legitimate Telstra support.
