Robocall Reports for 02 8320 4357
A contributor has reported receiving an automated robocall from 02 8320 4357 (also written as 0283204357). The call left a voicemail message in Chinese generated by an auto-recorder system. The contributor flagged this as a suspected scam and immediately blocked the number.
This NSW-based local service number from Symbio Networks Pty Ltd was used to deliver an automated message, which is a common tactic in robocall scams targeting Australian phone users.
What the Robocall Message Said
The voicemail left from 02 8320 4357 was delivered in Chinese by an automated system rather than a live caller. The contributor did not provide a full transcription of the message content, but the use of auto-recorded speech in a non-English language is a recognised pattern in international scam and spam campaigns. The brevity of the recorded message and the contributor's immediate suspicion suggest the call was designed to test whether the number was active or to initiate contact without requiring human interaction.
Call Details and Timing
The robocall to 02 8320 4357 arrived on 19 March 2026 in the early morning (07:50 UTC). The call did not reach the contributor in real-time but instead deposited a voicemail, which is typical behaviour for high-volume robocall campaigns that dial large contact lists and leave automated messages when calls go unanswered.
What to Do If You Receive a Call from 02 8320 4357
If 0283204357 calls you:
- Do not: Answer calls from unknown numbers, return calls to unknown numbers, or engage with voicemail messages in unfamiliar languages
- Do: Let calls go to voicemail, listen to messages in a safe environment (do not click any links or return calls), block the number immediately if suspicious, and avoid sharing any personal information
- For robocalls: Do not press any keypad numbers in response to automated prompts, as this confirms your number is active and may increase future robocall targeting

WRITE A REVIEWFrequently Asked Questions
Why did 02 8320 4357 leave a message in Chinese?
Robocalls from 0283204357 that use non-English languages are often part of international scam operations that target multiple countries simultaneously. Auto-recorded messages in foreign languages are cheaper to produce and deploy at scale. The language choice does not necessarily indicate the caller's origin - it is simply part of an automated dialling campaign.
Should I call back 0283204357 to ask who they are?
No. Do not return calls to 02 8320 4357. Calling back confirms to the scammer or robocall operator that your number is active and monitored by a real person, which increases the likelihood of future calls. If you need to identify a caller, use Reverseau to check community reports or contact the service provider directly using a known, legitimate phone number.
Is 02 8320 4357 a legitimate Symbio Networks number?
02 8320 4357 is registered as a local service number with Symbio Networks Pty Ltd in NSW, but this does not guarantee the call was legitimate. Scammers and robocall operators often spoof or hijack real phone numbers, or compromise telecom infrastructure to send automated messages. The robocall nature of the contact and the contributor's suspicion suggest misuse rather than an authorised Symbio Networks call.
What should I do if 0283204357 keeps calling me?
Block 02 8320 4357 in your phone's call settings or via your service provider. Most Australian carriers (Telstra, Optus, Vodafone, Symbio Networks, etc.) offer robocall filtering and blocking tools. You can also report the repeated calls to ACMA at acma.gov.au, which tracks patterns of harassment and can escalate serious cases.
Could the message from 02 8320 4357 contain malware or a scam link?
Voicemail messages alone cannot contain malware, but robocalls often include instructions to call back or visit a website. If the auto-recorded message from 0283204357 included a callback number or link, do not follow those instructions. Robocall voicemails are designed to trick recipients into taking action that benefits the scammer (confirming your number, visiting a phishing site, or transferring money).
How can I stop robocalls like the one from 0283204357?
Use your phone's built-in call filtering (Apple's Silence Unknown Callers, Android's Call Screen), enable carrier-level filtering through your provider (Symbio Networks offers call filtering options), register with the Do Not Call Register at donotcall.gov.au, and block individual numbers like 02 8320 4357 as they appear. Report persistent robocalls to ACMA to help protect other Australians.
