WRITE A REVIEWFrequently Asked Questions
Is 0485 080 300 a known scam number?
Two contributors have reported 0485 080 300 as suspicious based on missed calls with no voicemail left. This pattern - calling without leaving a message - is consistent with scam and spam operations. However, with only two reports, the number may also be a wrong number or a legitimate call with a technical issue. If you receive repeated calls from 0485 080 300 with no voicemail, it's safer to block it.
Why would 0485 080 300 not leave a voicemail?
Scammers and spam callers often don't leave messages because their goal is to reach specific targets or test if a number is active, rather than conduct legitimate business. Leaving a voicemail would identify them and give recipients a reason to report them. Contributors flagging 0485 080 300 noted this absence of a message as a red flag typical of scammer behaviour.
Should I call back 0485 080 300?
No. If 0485 080 300 calls you and leaves no voicemail, do not return the call. This is one of the safest responses to suspicious numbers. Returning calls to unknown numbers can confirm your phone is active to scammers and potentially expose you to further targeting.
What provider is 0485 080 300?
0485 080 300 is registered as an Optus mobile number. However, mobile numbers can be spoofed or used by scammers who acquire SIM cards or stolen accounts. The fact that this is an Optus number does not guarantee legitimacy, especially given the suspicious call patterns reported by contributors.
How many reports has 0485 080 300 received?
Two contributors have reported 0485 080 300 so far, both describing missed calls with no voicemail left. While this is a smaller number of reports, the consistent pattern across both - suspicious missed calls without follow-up messages - suggests this may be systematic behaviour from whoever is using this number.
Can I block 0485 080 300 on my phone?
Yes. Most Australian mobile phones allow you to block numbers directly. If you receive a call from 0485 080 300, you can block it through your phone's settings or call blocking app. You can also report it to your provider, Optus, and they may be able to take action if the number is confirmed as being used for scam or spam purposes.
