Community reports for 03 9003 1184 (0390031184): Callers impersonate Telstra and Optus, claim internet problems, request IP addresses and personal information.
Telstra and Optus Impersonation Reports for 03 9003 1184
Two contributors have reported calls from 03 9003 1184 (also written as 0390031184) involving impersonation of major Australian telecommunications providers. Both reports describe callers falsely claiming affiliation with either Telstra or Optus, typically referencing account or internet issues as a pretext to extract sensitive information.
What makes these calls particularly concerning is the inconsistency in the scam approach. One caller from 0390031184 initially claimed to represent Optus before switching to Telstra mid-call, a red flag that suggests the caller was either testing the target or recovering from a failed opening. This bait-and-switch tactic indicates low operational sophistication but high intent to deceive.
What Callers from 03 9003 1184 Claim
Contributors report callers from 03 9003 1184 opening with claims about internet connection problems or account issues. The caller's typical approach involves stating they are from Telstra or Optus, then pivoting to requesting the recipient's IP address. When challenged to provide proof of legitimacy, one caller from 0390031184 refused to supply an email confirmation or official letter, instead pushing harder for the personal information requested.
A second call from 03 9003 1184 followed a similar pattern, with the caller claiming to be from Telstra and referencing internet problems. However, this caller disengaged immediately when the recipient stated they were not a Telstra customer, hanging up rather than attempting to overcome the objection. This behaviour suggests the scammer may be working from a cold-calling list without verification of customer status.
Report Patterns and Timing
Both reports for 0390031184 came through answered calls rather than voicemails, indicating the scammers are reaching live targets. The reports span from mid-February to early March 2026, with no indication of repeated calls to the same contributor. One call occurred during early morning hours (01:26 UTC), while the other came in early morning Australian time (06:14 UTC), suggesting the caller may be operating outside standard business hours or from a timezone-displaced location.

WRITE A REVIEWFrequently Asked Questions
Why do callers from 03 9003 1184 claim to be from different providers?
One contributor received a call from 03 9003 1184 where the caller initially claimed to be from Optus, then switched to Telstra. This inconsistency suggests the scammer was either testing which provider the target uses or attempting to recover after a failed opening. Legitimate providers never change their identity mid-call. If 0390031184 calls you and switches between provider names, hang up immediately.
Should I give my IP address to someone claiming to be from Telstra?
No. Telstra and Optus never request IP addresses during unsolicited calls. If a caller from 03 9003 1184 or any number asks for your IP address, network details, or account information, it is a scam. Hang up, block the number, and report it to ACMA at acma.gov.au. Always verify by calling your provider directly using the number on your official bill.
What should I do if 0390031184 refuses to provide proof via email or letter?
This is a major red flag. Contributors report that callers from 03 9003 1184 refused to send confirmation emails or official letters when challenged. Legitimate telecommunications providers will always offer to send official documentation or have you call them back on the official number. If 0390031184 refuses this, end the call immediately and block the number.
Is it normal for Telstra to call about internet problems unsolicited?
Telstra may contact you if you report a fault or if there is a genuine service issue on your account. However, they will never ask for your IP address, passwords, or remote access to your device during an unsolicited call. If 03 9003 1184 calls claiming an internet problem and requesting personal details, it is a scam. Hang up and contact Telstra directly using the number on your bill or their website.
Why did one caller from 03 9003 1184 hang up when told we're not with Telstra?
The caller likely hung up because they were working from a generic cold-calling list without verification of which provider their target actually uses. This is typical of low-effort scamming operations. The fact that 0390031184 disengaged so quickly suggests they move on to the next number rather than adapting their pitch, which is why you may not receive repeated calls from this number.
How can I verify if a call about my internet is actually from Telstra?
Always end unsolicited calls and initiate contact yourself. Look up Telstra's official phone number on your bill or their website (telstra.com.au), then call that verified number to ask about any issues. Never call a number provided by an incoming caller, as 0390031184 demonstrates scammers can impersonate providers. Legitimate Telstra staff will have your account details on file and can verify you without requesting IP addresses or sensitive information.
