One contributor reports a suspicious missed call from 03 5357 4111 (0353574111) - Optus claims the number is disconnected but someone attempted contact.
Suspicious Activity Reported for 03 5357 4111
A single contributor has flagged 03 5357 4111 (also written as 0353574111) for suspicious calling behaviour. The report describes a missed call attempt where Optus informed the contributor that the number was disconnected, yet someone successfully used it to make contact. This disconnect between carrier status and actual call activity raises questions about the legitimacy of the calling party.
The call came from a Telstra-allocated local service number in Victoria, but the discrepancy between Optus's disconnection record and the actual call suggests either spoofing, number masking, or potential account compromise. This type of mismatch is occasionally associated with spoofed or misdirected calls.

WRITE A REVIEWFrequently Asked Questions
Why would Optus say 03 5357 4111 is disconnected if someone called me from it?
The number 0353574111 may have been disconnected from Optus's network, but callers can still use number spoofing technology to make it appear as though calls originate from that number. Alternatively, the number could have been briefly reactivated or the Optus information may be outdated. This inconsistency is a red flag for potentially deceptive calling practices.
Should I be concerned about the missed call from 03 5357 4111?
The missed call from 03 5357 4111 warrants caution. The fact that it came from a number Optus considers disconnected suggests the caller may be using deceptive tactics. Unless you recognise the caller or are expecting contact, do not return the call. Wait for a voicemail message to determine legitimacy.
Is 0353574111 a scam or spam number?
Based on current community reports, 0353574111 has been flagged once as suspicious due to the disconnect discrepancy. One report alone is insufficient to definitively classify it as scam or spam, but the circumstances are unusual enough to warrant caution. If you receive additional calls, report them to ACMA and contribute to Reverseau.
What should I do if 03 5357 4111 calls again?
If 03 5357 4111 contacts you again, do not answer or return the call. Block the number in your phone's settings. If the call is regarding an urgent matter (account lockout, delivery, urgent payment), independently verify the claim by calling the organisation's official support line using a number from their website or your bill.
Can I report this number to my phone carrier?
Yes. Contact your phone provider (in this case, Telstra allocated 03 5357 4111) and report the suspicious calling activity. They can investigate whether the number is being used for spoofing or fraudulent purposes. You can also report the number to ACMA at acma.gov.au for broader investigation.
What is number spoofing and how does it relate to 0353574111?
Number spoofing involves displaying a false phone number on the recipient's caller ID. The missed call from 03 5357 4111 may be spoofed, meaning the actual caller disguised their real number to appear as 0353574111 (a disconnected Optus number). This is a common tactic used by scammers and spammers to appear legitimate or to evade detection.
