Telstra Impersonation Reports for 03 9003 1104

Two contributors have reported calls from 03 9003 1104 (also written as 0390031104) where callers impersonated Telstra representatives. Both reports describe similar tactics: the caller claims there is a security issue with the recipient's internet connection or IP address, creating immediate alarm. One caller from 0390031104 claimed the internet connection was "now public" and hung up abruptly when challenged, a classic pressure tactic designed to prevent questions or verification.

The impersonation of Telstra is deliberate and calculated. Callers from 03 9003 1104 exploit the fact that most Australians have some relationship with Telstra, whether as current or former customers, making the claim superficially credible during the initial moments of contact.

What Callers from 03 9003 1104 Claim

Contributors who answered calls from 03 9003 1104 reported the following claims:

• "Your internet connection is now public" - one caller used this specific phrase before immediately hanging up
• "There is an issue with your IP address" - reported in a separate call from 0390031104
• Callers identified themselves as being from Telstra, using the company name to establish false authority
• The tone was urgent and designed to prompt immediate action or agreement

The brevity of one call from 03 9003 1104 (where the caller hung up straight away) suggests the scammer was testing whether the number would answer, or attempting to trigger a callback to 0390031104 from a concerned recipient.
