Medibank Impersonation Reports for 02 5740 7336
Two contributors have reported suspicious voicemails from 02 5740 7336 (also written as 0257407336) claiming to be from Medibank. Both reports describe the same tactic: callers leave messages instructing recipients to click a link to update their account details. This type of phishing attempt is designed to capture login credentials or personal information by impersonating a legitimate health insurance provider.
The number 0257407336 is allocated as a local service in NSW through Symbio Networks Pty Ltd, which gives it the appearance of legitimacy. However, Medibank does not contact customers via unsolicited voicemail links for account updates.
What Callers from 02 5740 7336 Say
Both contributors reported receiving identical voicemail messages from 02 5740 7336 claiming to be from Medibank. The caller instructed them to click a link to update their details. No legitimate bank or insurance company asks customers to click links in unsolicited messages to verify or update account information. This is a classic phishing tactic where clicking the link typically leads to a fake login page designed to steal credentials.
Report Patterns and Timing
Both reports arrived as voicemails on the same day (2 April 2026, early morning), suggesting the caller may be running a batch campaign targeting multiple numbers. The use of voicemail rather than direct conversation reduces the risk of immediate detection, as it gives the caller time to move on before recipients can question the request.

WRITE A REVIEWFrequently Asked Questions
Is 02 5740 7336 a real Medibank number?
No. Medibank's customer service numbers are listed on their official website (medibank.com.au). The number 02 5740 7336 (0257407336) is not a Medibank contact line. While it is allocated as a local service in NSW, scammers often use legitimate-looking local numbers to deceive recipients. Never click links or provide details based on unsolicited contact - always verify independently.
What happens if I click the link from 02 5740 7336?
Clicking the link from 02 5740 7336 typically takes you to a fake Medibank login page designed to steal your username, password, and personal information. Once compromised, attackers can access your health insurance account, claim details, and potentially your linked bank account. If you clicked the link, change your Medibank password immediately and monitor your account for suspicious activity.
Why would Medibank contact me about updating details?
Legitimate insurance companies rarely contact customers via unsolicited voicemail asking them to click links. If Medibank needs to contact you about your account, they will either mail you official documentation, contact you through their secure online portal (mymedbank), or ask you to call them directly. When you call, use the number on your insurance card or official website, not any number from an unexpected voicemail.
What should I do if I already gave my details to 02 5740 7336?
If you provided your Medibank login details or personal information to 0257407336, act immediately: change your Medibank password, enable multi-factor authentication if available, and contact Medibank's fraud team through their official website. Monitor your account for unauthorised claims and consider placing a fraud alert with your bank. You can also report the incident to Scamwatch (scamwatch.gov.au) and ReportCyber (cyber.gov.au).
Can I block 02 5740 7336 on my phone?
