Phishing Link Scam Reports for 04 5765 3300
One contributor has reported suspicious activity from 04 5765 3300 (also written as 0457653300), a mobile number registered with Telstra. The caller employed a phishing tactic, initiating contact via phone calls and then attempting to extract personal information through a voice recording system.
The contributor received two calls from 0457653300. When attempting to return the call to verify legitimacy, they reached an automated voice recording that requested personal details. This pattern indicates a phishing scam where the initial calls serve to prompt a callback, triggering the phishing mechanism.
What the Caller from 04 5765 3300 Does
The scammer uses a two-stage approach with 04 5765 3300. First, they make outbound calls to potential targets.

Upon callback to 0457653300, the victim encounters a voice recording designed to harvest personal information.
This callback phishing method is effective because it exploits the social norm of returning missed calls, making the victim believe they are initiating contact with a legitimate caller rather than falling victim to a scam.

WRITE A REVIEWFrequently Asked Questions
What is a callback phishing scam, and how does 04 5765 3300 use it?
A callback phishing scam uses outbound calls to prompt victims to call back, triggering a phishing voice recording. The contributor reported that 0457653300 called twice, and when they returned the call, an automated recording requested personal details. This tactic exploits the normal behaviour of returning missed calls.
Should I return calls from unknown mobile numbers like 04 5765 3300?
No. If you don't recognise the number, let it go to voicemail. Legitimate organisations will leave a message or use verified contact methods. If 0457653300 or similar numbers contact you and you wish to verify, independently look up the organisation's official number and call them directly rather than using any number from the voicemail.
Why would a scammer use a real Telstra mobile number like 0457653300?
Scammers use real mobile accounts (whether legitimately obtained, hacked, or rented from accomplices) because they appear more trustworthy than obvious spoofed numbers. A Telstra mobile like 04 5765 3300 may seem like a personal contact, increasing the likelihood that victims will return the call.
What should I do if I've already provided information to the voice recording from 04 5765 3300?
Contact your bank and relevant financial institutions immediately to alert them of potential fraud. Monitor your accounts for unauthorised activity. Report the incident to Scamwatch (scamwatch.gov.au), ACMA (acma.gov.au), and ReportCyber (cyber.gov.au). If your identity was compromised, consider placing a fraud alert with credit reporting agencies.
How can I block 04 5765 3300 on my phone?
On most Australian mobile phones, you can block a number directly from your recent calls list or by adding 0457653300 to a blocked contacts list in your settings. Contact your provider Telstra for additional blocking features. Blocking prevents the number from reaching you, though scammers may call from different numbers.
Are there other numbers using the same phishing tactic as 04 5765 3300?
Callback phishing is a common scam technique, and multiple numbers may employ it. If you receive suspicious calls from any number and are prompted to return a call that leads to an automated recording requesting personal information, treat it as a phishing attempt. Report all suspected numbers to Reverseau to help build community awareness.
