Repeated Calls and Callback Lure Reports for 0413 133 659
One contributor has reported receiving multiple missed calls from 0413 133 659 (also written as 0413133659), an Optus mobile number, with a distinctive pattern: no voicemail messages are left behind. When the recipient attempts to return the call to 0413 133 659, they reach only a generic message bank with no response. This behaviour is consistent with callback lure tactics, where callers rely on recipient curiosity to prompt a return call rather than engaging directly.
The pattern reported for 0413133659 suggests the caller is using the missed call itself as the hook, betting that the recipient will ring back out of concern or curiosity. This avoids direct engagement where the caller would need to pitch a scam or unwanted service, reducing exposure to reporting.
What This Pattern Indicates
The absence of a message combined with an unresponsive voicemail when 0413 133 659 is called back is a known callback scam indicator. Contributors who have encountered repeated calls from 0413133659 without accompanying messages should be cautious about returning the call, as the purpose is typically to generate billable calls or to trigger engagement with a scam process once the recipient dials back.
The fact that 0413 133 659 is an Optus mobile number does not confirm legitimacy; many callback scams originate from spoofed or compromised mobile accounts.
Call Patterns and Behaviour
The contributor reported multiple missed calls from 0413 133 659, indicating a persistent calling pattern rather than a one-off misdial. The repeated attempts to contact followed by silence when called back suggest deliberate callback lure tactics rather than genuine communication attempts. This pattern of multiple missed calls with no message left is typical of nuisance calling campaigns designed to provoke a return call without committing the caller to explain their purpose.
What to Do If You Receive a Call from 0413 133 659

WRITE A REVIEWFrequently Asked Questions
What is a callback lure scam?
A callback lure occurs when a caller (often using a spoofed or compromised number like 0413 133 659) deliberately rings and hangs up or doesn't leave a message, hoping you'll become curious and ring back. Once you call 0413133659, the scammer may connect you to a sales pitch, charge you for the call, or initiate a scam conversation. The callback itself is the objective.
Why doesn't 0413 133 659 leave a voicemail message?
Callers using callback lure tactics intentionally avoid leaving messages because a message would explain their purpose and allow you to decide whether to engage. By leaving only a missed call from 0413 133 659, they rely on your curiosity or concern to prompt a return call to 0413133659, putting you in the position of initiating contact.
Should I call back 0413 133 659?
No. If you don't recognise 0413 133 659 and the caller left no message, there is no legitimate reason to return the call. Calling back 0413133659 is exactly what the caller wants. If it were important, they would have left a voicemail or sent a message explaining their reason for calling.
What happens if I return the call to 0413 133 659?
When you call back 0413 133 659, you may hear a generic voicemail (as reported), be connected to a sales pitch, charged for the call, or enter a conversation designed to extract personal information or money. The contributor who reported 0413133659 found only an unresponsive message bank, but other outcomes are possible depending on the scam's purpose.
Is 0413 133 659 a real Optus number?
0413 133 659 is assigned to Optus mobile, but this does not confirm it's being used legitimately. Scammers frequently use spoofed numbers, compromised accounts, or numbers bought specifically for callback lure campaigns. A legitimate caller would identify themselves and leave a message rather than relying on missed calls to provoke a callback.
How do I block 0413 133 659 permanently?
Most mobile phones allow you to block numbers directly: save 0413 133 659 as a contact, mark it as spam or blocked, or use your phone's native call-blocking feature. You can also register with the Do Not Call Register at donotcall.gov.au and report 0413133659 to ACMA at acma.gov.au. If the calls persist after blocking, contact your provider Optus for additional filtering options.
