Under the Spam Act 2003 it is illegal to send, or cause to be sent, unsolicited commercial electronic messages. The Act covers email, instant messaging, SMS and MMS (text and image-based mobile phone messaging) of a commercial nature. It does not cover faxes, internet pop-ups or voice telemarketing.
The ACMA is responsible for enforcing the Spam Act and actively works to fight spam in Australia. This section of the ACMA’s website provides practical information and handy tips on how you can reduce and help to fight spam.
