Three contributors have flagged 02 8529 5775 (also written as 0285295775) for silent and suspicious calling behaviour. The most concerning pattern involves silent calls where the line goes dead when answered, combined with reports of coordinated calling activity.

What Callers from 02 8529 5775 Do

The coordinated calling pattern reported by one contributor is particularly significant. Receiving calls from 02 8529 5775 alongside multiple other unknown numbers in quick succession suggests a batch calling campaign rather than a one-off wrong number. The absence of voicemails on any of the calls indicates the caller's goal was to establish contact rather than leave a message.

Reports about 0285295775 span from January 2024 through March 2026, suggesting this number has been active in calling campaigns over an extended period.

What to Do If You Receive a Call from 02 8529 5775
Silent calls and callback scams rely on you answering and confirming your number is active. If 02 8529 5775 calls:
- Do not: Confirm your number verbally, stay on the line, or press any keys if prompted
- Do: Let the call go to voicemail, hang up immediately if you answer, and block the number
- Do: Avoid calling the number back, even out of curiosity, as this confirms active contact
- Do: Be alert to scam calls in the following days or weeks, as verified numbers are often targeted with follow-up campaigns
If you receive multiple calls from different numbers in a short timeframe, this is a strong indicator of a verification campaign. Block all unknown numbers from that period.

WRITE A REVIEWFrequently Asked Questions
Why do scammers make silent calls from 02 8529 5775?
Silent calls from 02 8529 5775 (0285295775) serve as automated verification that your number is active and answered by a real person. Scammers use this confirmation to prioritise your number for follow-up scam campaigns. Contributors who received silent calls from 02 8529 5775 should expect potential scam contact attempts in the following weeks from different numbers.
What should I do if 02 8529 5775 calls me back when I call the number?
If you call 0285295775 back and someone answers but remains silent, do not engage. Hang up immediately without speaking. Do not press any keypad numbers or say anything that confirms the line is answered. Contributing this pattern to Reverseau helps identify whether 02 8529 5775 is operating a coordinated callback scam network.
Is 02 8529 5775 a legitimate business number?
02 8529 5775 is allocated to Symbio Networks Pty Ltd as a local service in NSW, but the reported calling behaviour (silent calls with no engagement, multi-number coordination) is inconsistent with legitimate business use. The number has not left voicemails or identified itself when called, which legitimate businesses routinely do. The silent call tactic is a known scam indicator.
What is a callback scam and how does 02 8529 5775 fit the pattern?
A callback scam uses silent calls from 0285295775 to verify your number is active, then either sells your verified number to other scammers or targets it with follow-up scams later. One contributor received 02 8529 5775 calling alongside four other unknown numbers within 90 minutes - this coordinated pattern is a hallmark of callback verification campaigns.
Can I block 02 8529 5775 on my phone?
Yes. Block 0285295775 through your phone's built-in call blocking feature or request blocking from your phone provider. However, blocking one number does not prevent scammers from calling with different numbers. If you received the silent call from 02 8529 5775 after your number was verified, expect follow-up scam attempts from various numbers in the coming weeks.
Should I report 02 8529 5775 to ACMA or Scamwatch?
Yes, report 0285295775 to both ACMA (acma.gov.au) for silent call complaints and Scamwatch (scamwatch.gov.au) for the suspicious callback pattern.
