Five contributors have reported calls from 03 9003 1100 (also written as 0390031100), with patterns ranging from outright impersonation to persistent nuisance calling.

What Callers from 03 9003 1100 Say
One contributor reported receiving a call from 03 9003 1100 where the caller claimed direct affiliation with Telstra. This impersonation attempt exploits the familiarity Australians have with Telstra customer service, creating false authority to potentially manipulate the recipient into sharing sensitive information or authorising account changes.
A separate report describes a cold call from 0390031100 promoting a loan service the contributor considered suspicious. The caller made unsolicited sales pitch rather than responding to any inquiry, characteristic of aggressive telemarketing or predatory lending schemes.
Another contributor who answered a call from 03 9003 1100 reported that a woman insisted they had spoken previously. When the contributor denied prior contact, the caller immediately hung up - behaviour consistent with either list verification or a caller backing away when challenged.
Call Patterns and Persistence
Multiple contributors have experienced repeated contact from 03 9003 1100 without voicemail messages, indicating intentional persistence rather than genuine service attempts. One contributor noted the number keeps calling but won't leave a message, a pattern typical of either robocall campaigns or callers deliberately avoiding documentation of their pitch.
Reports from 0390031100 span from mid-February through late March 2026, suggesting ongoing activity rather than isolated incidents. The mix of answered and missed calls indicates the number is being dialled to multiple recipients across different times.
What to Do If You Receive a Call from 03 9003 1100
If 03 9003 1100 calls you:
- Do not: Answer if you don't recognise the number, return the call, or provide any personal information such as account details, passwords, or financial data
- Do: Let it go to voicemail, block the number immediately if it calls repeatedly, and if claiming to be from Telstra, hang up and independently call Telstra's official customer service line to verify
- For Telstra impersonation claims: Never share account information with unsolicited callers. Telstra will never ask for passwords or full account details over the phone. Verify any claimed Telstra communications by contacting 13 2200 directly using a number you look up independently

WRITE A REVIEWFrequently Asked Questions
Is 03 9003 1100 actually calling from Telstra?
No. One contributor reported that a caller from 03 9003 1100 falsely claimed to represent Telstra. This is a known impersonation tactic. Telstra will never cold-call claiming problems with your account or asking you to verify information. If you're unsure about a Telstra communication, hang up and call Telstra directly on 13 2200 using a number you look up independently. Never call back the number that called you.
Why does 0390031100 keep calling without leaving a message?
A contributor reported that 03 9003 1100 calls repeatedly but doesn't leave voicemail messages. This pattern is typical of either automated robocall campaigns or callers deliberately avoiding documentation of their pitch. Legitimate service providers typically leave messages explaining why they called. Repeated calls without messages suggest the caller is either harvesting active phone numbers or running a campaign where persistence is the strategy.
What loan service was being sold from 03 9003 1100?
One contributor described receiving a cold call from 0390031100 pushing a loan service they considered 'scammy'. The caller made an unsolicited sales pitch rather than responding to any inquiry. The contributor did not provide details of the specific lender, but the characterisation as suspicious combined with cold-calling tactics suggests caution is warranted. Never provide banking or financial details to unsolicited callers.
Should I block 03 9003 1100?
Yes. If 0390031100 has called you, blocking it is recommended. Multiple contributors have reported persistent calls from 03 9003 1100 without clear legitimate purpose. Blocking prevents further contact and stops the number from confirming your line is active, which can reduce future unsolicited calls. Most modern phones allow you to block numbers and report them as spam directly through settings.
What should I do if someone from 03 9003 1100 claims to be verifying a previous conversation?
Treat this as suspicious. One contributor reported a woman from 03 9003 1100 insisting they had spoken before, then hanging up immediately when challenged. This tactic is often used to establish false familiarity or to verify that your number is active. Do not confirm previous conversations you don't remember, do not provide information based on claimed prior contact, and hang up if you're unsure.
How do I report 0390031100 to authorities?
Report 03 9003 1100 to Scamwatch (scamwatch.gov.au) for impersonation and scam attempts, and to ACMA (acma.gov.au) for spam and nuisance calls. Include the date, time, and what the caller claimed. For Telstra impersonation specifically, also contact Telstra directly at 13 2200. Register your number on the Do Not Call Register at donotcall.gov.au, though this won't stop determined scammers.
