Nuisance and Uncertain Reports for 03 9003 5511
Two contributors have flagged calls from 03 9003 5511 (also written as 0390035511) as nuisance or uncertain in nature. The pattern involves hang-ups on answer and missed calls with no message left behind, which are common hallmarks of automated calling campaigns or number-checking behaviour.
One contributor answered when 03 9003 5511 called and reported the caller hung up immediately. Another received a missed call from 0390035511 with no voicemail, leaving them uncertain about the caller's intent. The lack of follow-up messages or callback attempts suggests this may be a robocall or automated dialling system testing active numbers.
Call Patterns for 03 9003 5511
Reports span from late February to early March 2026. One call came during business hours (around 11:43 AM on 27 February), while the other occurred in the early morning hours (1:41 AM on 11 March). The timing spread and lack of voicemail suggests either an automated system or bulk calling operation rather than a targeted contact attempt.
With only two reports so far, 0390035511 appears to be in early stages of contributor awareness. However, the pattern of answering and immediately disconnecting is consistent with number-validation behaviour used by spam operations to confirm active numbers for later targeting or sale to other callers.

WRITE A REVIEWFrequently Asked Questions
What does it mean when a caller from 03 9003 5511 hangs up immediately?
Immediate hang-ups after you answer are often a sign of automated dialling or number-validation systems. One contributor reported exactly this behaviour from 03 9003 5511. These systems test whether a number is active and answered by a real person, then disconnect. The data collected is often sold to other callers or used for future targeting. Hanging up suggests the caller wasn't attempting genuine contact.
Why would 0390035511 call but leave no voicemail?
A missed call with no voicemail from 0390035511 typically indicates the caller's primary goal wasn't to deliver a message. If it were a legitimate business, they would leave a callback number and reason for calling. One contributor received this exact pattern from 03 9003 5511. Legitimate callers (banks, utilities, services) almost always leave voicemail when a call isn't answered, so the absence suggests a robocall or spam operation.
Should I call back a number like 03 9003 5511 that called me?
No. Returning a call to 03 9003 5511 or 0390035511 is not recommended, especially after a hang-up or missed call with no voicemail. Calling back confirms your number is active and monitored, which may result in more unwanted calls. The pattern reported for 03 9003 5511 (immediate hang-up) suggests this is precisely what the caller wants - confirmation that your line is in use.
Is 03 9003 5511 definitely a scam?
Based on current reports, 03 9003 5511 is flagged as nuisance or uncertain rather than confirmed scam. One contributor described it as 'feels like a scam' after a missed call with no message from 0390035511, but without actual scam content (fake claims, threats, requests for money), it cannot be definitively confirmed as such. However, the hang-up and no-voicemail pattern is consistent with spam behaviour. If you receive contact from 03 9003 5511 with an actual message or demand, report it to Scamwatch.
How can I block calls from 0390035511?
Most Australian phones allow you to block numbers directly. On iPhone, open the Phone app, find 0390035511 in your call history, tap the info icon, and select 'Block this Caller'. On Android, open Phone, find 03 9003 5511, tap the menu, and select 'Block number'. You can also check your carrier's filtering tools - Telstra, Optus, and Vodafone all offer free spam filtering. If calls from 03 9003 5511 continue and you've registered with the Do Not Call Register, report to the ACMA.
What should I do if 03 9003 5511 calls again?
If you receive another call from 03 9003 5511, let it go to voicemail rather than answering. Block the number using your phone's built-in tools. If you receive multiple calls from 0390035511 over time, take note of the dates and times, then report to the ACMA at acma.gov.au. You can also report to the Do Not Call Register at donotcall.gov.au if the calls continue after registration. Sharing your experience on Reverseau helps other Australians recognise this number.
