NBN Impersonation Reports for 03 9003 1159
Two contributors have reported calls from 03 9003 1159 (also written as 0390031159) involving scammers impersonating NBN or internet service providers. Both reports describe callers with accents making unsolicited contact about supposed internet or NBN security issues, despite the number appearing to be Australian when received.
The pattern across reports of 0390031159 is consistent with known NBN impersonation tactics, where callers fabricate technical problems to gain trust before requesting sensitive information or payment. Contributors noted the calls were deceptive in origin, masking the actual source behind what looked like a local Australian number.
What Callers from 03 9003 1159 Claim
One contributor received a call from 03 9003 1159 where the caller, speaking with an Indian accent, claimed there were security problems with the recipient's NBN connection. When the contributor challenged the caller and accused them of criminal activity, the caller immediately hung up without further engagement.
A separate report about 0390031159 involved a female caller with an accent claiming the recipient's internet licence was "in public domain." This is a known impersonation tactic designed to create false urgency and concern about privacy or security. The caller attempted to continue the conversation but ultimately disconnected when the contributor did not respond as expected.
Report Patterns and Timing
Both reports of 03 9003 1159 came in March 2026, within a week of each other. The calls were answered by contributors, allowing them to hear the caller's accent and claims directly. The rapid hang-up behaviour when challenged or when the caller failed to elicit a response suggests a high-volume contact strategy typical of impersonation scam operations.

WRITE A REVIEWFrequently Asked Questions
What should I do if someone calls from 03 9003 1159 claiming to be from NBN?
Hang up immediately. NBN Co will never cold-call you about security problems or internet licences. If you have a genuine NBN issue, contact NBN Co directly using the number on your bill or visit nbnco.com.au. Do not call back 0390031159 or any number the caller provides.
Why do callers from 03 9003 1159 have accents but show an Australian number?
Scammers use technology to mask their true location and make calls appear to come from Australian numbers when they originate overseas. The accent and false claims about NBN are deliberate social engineering tactics designed to catch people off guard. Never trust the number format alone - verify the caller's identity through official channels.
What does 'internet licence in public domain' mean when called by 0390031159?
It's a fabricated claim with no basis in Australian law. There is no such thing as an internet licence that can be in public domain.

No. Engaging with 0390031159 or any suspected scam caller gives them opportunity to refine their pitch, build false rapport, or extract information. The safest approach is to hang up without explanation. You do not owe scammers conversation time or courtesy.
