Telstra Impersonation and Robocall Reports for 02 7241 7543

Two contributors have flagged calls from 02 7241 7543 (also written as 0272417543) for suspicious impersonation and automated calling activity. The reports describe different attack methods from the same number, including a caller falsely claiming Telstra affiliation and requesting sensitive network information, alongside an automated robocall with recorded Mandarin-language prompts.

The number is allocated as a local service in NSW through Symbio Networks Pty Ltd. This allocation pattern, combined with social engineering tactics targeting home network access, suggests the number may have been spoofed or compromised for scam purposes.

What Callers from 02 7241 7543 Have Claimed

One contributor received a call where the person claimed to represent Telstra and specifically asked about their IP address. This is a classic phishing tactic designed to gather network information that could be used for further exploitation or identity theft. The contributor immediately declined and instructed the caller not to contact them again.

A second report describes a recorded message in Mandarin delivered by a female voice, presenting an automated menu system asking the recipient to press numbered keys for different options. The contributor noted the interaction felt suspicious and untrustworthy. This type of robocall often precedes scam attempts or attempts to verify active phone numbers for later targeting.

Report Patterns and Timing

One call was received and answered directly, allowing the contributor to interact with the live impersonator before refusing engagement. The other report involved an automated robocall with no option to speak to a real person. The Mandarin-language robocall was logged in March 2025, while the Telstra impersonation attempt occurred in February 2026, suggesting this number may be used repeatedly for different scam campaigns over time.
