Robocall Reports for 04 6800 0509
A contributor has flagged 04 6800 0509 (also written as 0468000509) for robocall activity. The report describes a distinctive pattern: an initial pause followed by a ring, consistent with automated dialler behaviour. This is a mobile number allocated to Optus.
What the Contributor Experienced
The contributor who answered the call from 0468000509 reported receiving what appears to be an automated dialler. Rather than an immediate voice or message, the call opened with a noticeable pause, followed by a ring sound. This pattern is typical of robocall systems that screen incoming calls and route answered numbers through to live operators or trigger pre-recorded messages. The contributor did not report hearing a voice message or sales pitch, suggesting the dialler may have disconnected or was still connecting when they picked up.
Why Robocalls Matter
Robocalls from numbers like 04 6800 0509 are problematic even when no message follows. Automated diallers confirm your number is active and monitored, making you a higher-priority target for future contact attempts. These systems often target multiple numbers simultaneously and are frequently used by scam operations, telemarketing campaigns, or verification systems for compromised contact lists. The pause-then-ring pattern reported for 0468000509 suggests a commercial-grade autodial system rather than a one-off call.

WRITE A REVIEWFrequently Asked Questions
What does a robocall pause-and-ring pattern mean?
The pause-then-ring pattern reported for 04 6800 0509 is a signature of automated dialling systems. When you answer, the system briefly connects and may play a ring tone or silence while routing your call to a live operator or checking if you're a valid target. The contributor's experience with 0468000509 indicates a commercial autodial setup, not a personal or random call.
Should I call back 04 6800 0509?
No. Calling back 0468000509 confirms your number to the operator and may trigger future contact attempts. If the call was from an automated system, returning the call could connect you directly to a scammer or sales operation. Block 04 6800 0509 and do not engage.
Is 04 6800 0509 definitely a scam?
The single report about 0468000509 describes robocall behaviour consistent with automated dialling, which is often associated with scams or illegitimate telemarketing. However, one report of robocall activity alone does not confirm criminal intent. The Optus mobile number could also be spoofed. Monitor for additional calls from 04 6800 0509 and report if contact continues.
Can I block robocalls from 04 6800 0509?
Yes. On most Australian phones, you can block 0468000509 directly in your phone's settings or contact app. Mark the number as 'block' or 'spam'. If you receive robocalls from different numbers, consider enabling your phone's robocall filter. iPhone users can enable 'Filter Unknown Senders' and Android users can use Google's Call Screen or third-party call-blocking apps.
Why does 04 6800 0509 show as an Optus mobile number?
The number 0468000509 is allocated to Optus as a mobile service. However, robocallers and scammers frequently spoof legitimate phone numbers, including Optus mobile numbers, to make their calls appear trustworthy. The caller may not actually be using this Optus account. Report the suspicious activity to ACMA at acma.gov.au if you believe the number has been compromised.
What should I do if this robocall leads to a sales pitch or scam?
If 04 6800 0509 or 0468000509 connects to a voice message or live caller attempting to sell something or request personal information, hang up immediately without engaging. Do not press any keys or confirm your details. Then block the number, report it to Scamwatch at scamwatch.gov.au, and contact ACMA. If money or identity theft is involved, also report to ReportCyber at cyber.gov.au.
