Telstra and Optus Impersonation Reports for 03 9022 9551

Three contributors have flagged calls from 03 9022 9551 (also written as 0390229551) for impersonation scams targeting registered users of major Australian telecommunications providers. The pattern involves callers claiming affiliation with Telstra Security or Optus, referencing account registration or internet security concerns to establish false legitimacy.

Callers from 0390229551 are using familiar telco names to create urgency around security threats, a tactic designed to bypass natural scepticism. When challenged directly, the behaviour escalates - one contributor who called out the scammer received four follow-up calls from different phone numbers, suggesting the caller was attempting damage control or intimidation.

What Callers from 03 9022 9551 Claim

One contributor received a call at 9:30 PM from 03 9022 9551 asking about their registration. When the recipient questioned the legitimacy and called the caller a scammer, the response was aggressive callback attempts from multiple different numbers within the same conversation.

Another report describes a caller explicitly claiming to be from Telstra Security, providing just enough specificity to sound credible without offering genuine technical details. A separate incident involved a caller impersonating Optus, mentioning internet security as the hook to trigger concern about account access or service disruption.

The common thread across reports of 0390229551 is that callers use major telco brand names and vague security references without providing case numbers, incident IDs, or verifiable account details that legitimate providers would offer.

Report Patterns and Timing

All three reports about 03 9022 9551 came in via answered calls, indicating the scammers are making live attempts rather than leaving voicemails. One call occurred at 9:30 PM, suggesting this operation may target evening hours when recipients are less vigilant. The most recent report came in January 2026, with an earlier incident in December 2025, indicating ongoing activity.

The escalation pattern in one report - initial call followed by four rapid callback attempts from different numbers - suggests automated systems or a coordinated team working the same target. This behaviour is atypical of legitimate telco outreach and consistent with scammers attempting to intimidate or wear down victims into compliance.
