One contributor reported suspicious calls from 04 0281 8312 (0402818312) that rang multiple times then dropped. Optus mobile number with unclear intent.
Uncertain Activity Reported for 04 0281 8312
A single contributor has flagged calls from 04 0281 8312 (also written as 0402818312) with unclear intent. The Optus mobile number rang multiple times before disconnecting, leaving the recipient uncertain about the caller's purpose or identity. The contributor noted unusual behaviour - the pattern of repeated calls followed by disconnection created suspicion but lacked the defining characteristics of a known scam or spam category.
What Happened When This Number Called
The contributor received multiple calls from 0402818312 that dropped off rather than connecting to a live person or voicemail. This pattern of ringing and disconnecting without leaving a message fits several possibilities: accidental repeated dialling, callback loop testing, or a failed automated dialling system. The contributor described the experience as having "strange vibes," indicating the behaviour felt intentionally evasive rather than a simple wrong number.
When the Call Occurred
The report of calls from 04 0281 8312 was logged in early February 2026. Without additional reports showing a pattern of calls at specific times or days, it remains unclear whether this was a one-off incident or recurring activity.
What to Do If You Receive a Call from 04 0281 8312
If 0402818312 calls you:
- Do: Let it go to voicemail if it rings multiple times without connecting
- Do: Block the number if calls continue or feel suspicious
- Do: Check your recent contacts and outgoing calls to rule out your own accidental dialling
- Do not: Return the call if you don't recognise the number
- Do not: Answer if the pattern repeats with multiple short rings
If the calls persist or escalate to aggressive messaging, document the activity and report it through official channels.

WRITE A REVIEWFrequently Asked Questions
Why did 04 0281 8312 ring multiple times then hang up?
The contributor reported this pattern but the reason remains unclear. It could be accidental repeated dialling, a system testing callback routes, or an automated dialler that disconnects before connecting. Without additional reports, it's difficult to determine intent. If 0402818312 continues this pattern, document the times and dates to identify whether it's targeted harassment or a technical issue.
Is 0402818312 definitely a scam?
Not necessarily. The single report describes uncertain activity rather than a confirmed scam. The pattern of ringing and dropping off doesn't match typical scam tactics like aggressive demands, impersonation, or phishing. It could be wrong number attempts, a glitchy dialler, or someone probing whether the number is active. If you receive similar calls from 04 0281 8312, observe the pattern before assuming malicious intent.
What should I do if 04 0281 8312 keeps calling?
Block the number on your phone to prevent future calls. If the calls continue from different numbers or escalate to messages, report to ACMA (acma.gov.au). Keep a record of call dates and times. Since 0402818312 is an Optus mobile, you can also contact Optus directly to report the activity.
Could 04 0281 8312 be a wrong number?
Possibly. A single call or even multiple short rings followed by disconnection sometimes indicates accidental dialling, especially if the number is similar to one someone has saved incorrectly. However, a pattern of deliberate multiple calls suggests either targeted activity or a system issue. If it's truly accidental, blocking 0402818312 will stop future calls.
Should I call back 0402818312?
No. If a caller rings you and hangs up, returning the call gives them confirmation your number is active and monitored. This can lead to more aggressive calling campaigns. If 04 0281 8312 genuinely needs to reach you, they will leave a voicemail or follow up with a message. Let it go to voicemail instead.
How can I help identify what 04 0281 8312 wants?
If you receive calls from 0402818312, report your experience on Reverseau. Include details like: time of day, how many times it rang, any voicemail left, and whether the pattern repeats. Additional reports help build a clearer picture of whether this Optus mobile is engaged in targeted activity or if the suspicious behaviour was isolated.
