Telstra Impersonation Report for 04 8511 9557
One contributor has reported receiving a call from 04 8511 9557 (also written as 0485119557) where the caller claimed to be from Telstra. The caller disconnected shortly after making the claim, which raised immediate suspicion given that 0485119557 is allocated to Optus mobile, not Telstra.
The quick hang-up is a notable pattern in impersonation scams - callers often disconnect when they sense scepticism or if the target appears informed about their actual carrier. This behaviour suggests the caller may have been testing the line or switching tactics when challenged.
What the Caller Claimed
The contributor reported that the caller from 04 8511 9557 claimed affiliation with Telstra. No further details about the nature of the claim, urgency, or requested actions were provided before the call ended. The brevity of the interaction and the mismatch between the claimed identity (Telstra) and the actual service provider (Optus) are the key red flags noted in this report.
Why This Impersonation Matters
Callers impersonating major Australian telecommunications providers like Telstra often attempt to gain trust quickly to extract sensitive information such as account numbers, payment details, or personal identification. The fact that 0485119557 is an Optus number being used to claim Telstra affiliation is a deliberate deception tactic. Legitimate Telstra representatives would contact you from Telstra infrastructure, not competitor networks.

If 04 8511 9557 calls you:

WRITE A REVIEWFrequently Asked Questions
Why would someone call from an Optus number claiming to be from Telstra?
Scammers often use VOIP services or spoofed numbers rather than their actual identity. In this case, the contributor noted that 0485119557 is allocated to Optus mobile, making the Telstra claim clearly false. This mismatch is a strong indicator of impersonation. Legitimate service providers contact you from their own infrastructure.
Is 04 8511 9557 a known Telstra number?
No. The phone number 04 8511 9557 (0485119557) is allocated to Optus mobile, not Telstra. If someone calls you from this number claiming to represent Telstra, they are not being truthful about their identity. Always verify independently by hanging up and calling the official customer service line on the back of your bill or their official website.
What should I do if a caller from 04 8511 9557 hangs up on me?
A quick hang-up from 04 8511 9557 often indicates the caller sensed skepticism or realised their deception wouldn't work. Do not call back. Block the number to prevent further contact, and report the call to Scamwatch at scamwatch.gov.au. If the caller contacts you again, let it go to voicemail and report the pattern to ACMA.
Can I trust a caller who says they're from Telstra but calls from 0485119557?
No. A legitimate Telstra representative would never call you from an Optus mobile number (0485119557). If you need assistance with your Telstra account, hang up and contact Telstra directly using the number on your bill or their official website. This ensures you're speaking to a genuine representative, not someone using 04 8511 9557 for impersonation.
What personal information should I never share with someone claiming to be from Telstra?
Never share your account number, PIN, password, credit card details, Medicare number, driver's license number, or any personally identifiable information with unsolicited callers, even if they claim to be from 04 8511 9557 or any telecommunications provider. Legitimate providers will never ask for full passwords or PINs over the phone.
