Australia SMS messaging regulations and restrictions

There are complex laws governing Australian SMS messaging, with many restrictions on the types of messages that can be sent to handsets. Most networks provide delivery receipts but bear in mind that your messages are unlikely to be delivered if they’re flagged as spam.

Direct marketing messages cannot be sent to handsets without prior consent from the recipient. Generally, express consent is required (for example, by means of an SMS), but in some cases, consent may be inferred through an existing relationship. View detailed restrictions in the table below or visit the Australian Communications and Media Authority for more information.

It’s a good idea to work with a sales advisor to ensure compliance with all Australian SMS regulations. Get in touch now and set up your messaging program with the help of our experts.
