Stop Unwelcome or Nuisance Calls & Messages

An unwelcome call is any type of call that you consider to be unwanted and can include:

  • Hang up calls
  • Silence
  • Hoax calls
  • Obscene, abusive or malicious calls
  • Reverse charge calls including '1800 Reverse'
  • SMS or MMS Messages
  • Operator assisted calls where the caller uses an operator to call your phone
  • Electronic tones made by fax or modem equipment

Trace unwelcome calls or messages

To request an unwelcome call / message trace, contact us with the following information:

  • Specific times and dates of 3 or more unwelcome calls/messages that were received over a 2 to 5 day period; that are not more than 4 weeks old; or
  • Specific times and dates of unwelcome calls/messages received at exactly the same time of day on the same day of the week over 3 or 4 consecutive weeks; or
  • Where excessive calls/messages have been received in 1 day, a minimum of 10 specific dates and times of calls received within a 24 hour period
  • If calls do not meet this criteria you can report the matter to the police and if necessary they will contact us to investigate.

Important: For Optus to take action, dates and times provided must be accurate (to the nearest minute)

What happens next?

Any action taken by Optus is under strict guidelines that are available in The Communications Alliance Industry Code

First stage

If a successful trace is completed then a warning letter is sent to the owner of the offending number advising them that what they're doing is an offence, the letter requests them to stop. The owner of the offending number has 14 days to comply with this request.

Second stage

If the calls / messages continue after a further 14 days, call us on 133 937 and report more dates and times. If this trace is successful a second warning letter is sent. The owner of the offending number has a further 14 days to comply with the request.

Third stage

If the calls/ messages continue after another 14 days, call us on 133 937 and report more dates and times. If this trace is successful, a third and final warning letter is sent and at this point the offending phone number can be suspended or cancelled, regardless if the number is with another service provider or with Optus.

Please note:

  • Times and dates may not be more than 4 weeks old. If you cannot provide the above then a trace cannot be conducted
  • Optus can trace calls/messages from overseas/payphones, but unfortunately no action other than changing your number can be taken.
  • Unfortunately Optus cannot block an individual number from calling or messaging you.
  • Optus can only release information regarding the number calling or messaging you to the Police or if we receive a subpoena from the courts.
  • The release of information is controlled by the Communications Alliance Industry code. The code can be viewed here.
  • More information regarding Optus' privacy policy can be viewed here
