Telstra Impersonation Reports for 04 8159 7787
One contributor has reported a scam call from 04 8159 7787 (also written as 0481597787) impersonating Telstra customer support. The caller claimed to be contacting the recipient about urgent internet security issues, using a common impersonation tactic to create pressure and bypass natural scepticism.
The call originated from an Optus mobile number, though the caller falsely identified as Telstra. This mismatch between actual provider and claimed identity is a red flag typical of impersonation scams.
What the Caller from 04 8159 7787 Said
The contributor reported that the caller from 0481597787 claimed there were security problems affecting their internet connection. When the recipient asked for a callback number to verify the caller's legitimacy, the caller immediately vanished and hung up.

Legitimate Telstra representatives will always provide verifiable contact details and allow callbacks through official channels. The caller's refusal to provide a callback number when challenged strongly suggests fraudulent intent.

WRITE A REVIEWFrequently Asked Questions
Why did the caller hang up when I asked for a callback number?
Scam callers typically cannot provide legitimate callback details because they are not actually representing the organisation they claim to be. When challenged on 04 8159 7787, this caller immediately disconnected rather than risk further verification, which confirms the fraudulent nature of the call. Legitimate companies like Telstra always provide verifiable contact information and encourage verification.
How do I verify if Telstra has actually contacted me?
Never rely on a phone number provided by an unsolicited caller. If you receive a call claiming to be from Telstra about security issues, hang up and contact Telstra directly using the phone number on your bill, your account statement, or the official Telstra website. This ensures you are speaking to a genuine representative, not someone posing as Telstra like the caller from 0481597787.
What should I do if I already provided information to 04 8159 7787?
If you shared personal details, banking information, or allowed remote access, contact your internet provider immediately and consider changing passwords for any accounts. Monitor your accounts for suspicious activity. Report the call from 04 8159 7787 to ACMA (acma.gov.au) and Scamwatch (scamwatch.gov.au) as soon as possible to protect other Australians.
Why is this number listed as Optus mobile but claiming to be Telstra?
Scammers often use spoofed or hijacked numbers to mask their true identity. The fact that 0481597787 is registered as an Optus mobile while the caller impersonated Telstra is a deliberate deception technique. This mismatch should immediately alert you to the scam, as legitimate companies use their own official contact lines.
Is it safe to call back 0481597787 to report the scam?
No. Do not call back 04 8159 7787 as it may trigger additional scam activity or expose you to further fraudulent schemes. Instead, report the number directly to ACMA and Scamwatch using their official websites, or contribute your report to Reverseau to warn the community about this number.
What is Telstra's standard process for security notifications?
Legitimate Telstra security alerts come through verified channels: your myTelstra account, official Telstra email addresses, or calls from Telstra's actual support lines (not random mobile numbers like 04 8159 7787). Telstra will never pressure you for immediate action or refuse to provide verifiable callback details. If you're unsure about a security claim, always hang up and contact Telstra directly using the number on your bill.
