The Spam Regulations 2021 are a Commonwealth legislative instrument made under the Spam Act 2003. The instrument was made on 18 March 2021, registered on 22 March 2021, and the whole instrument commenced on 1 April 2021.
For most businesses, these regulations are best understood as a targeted set of operational rules rather than a complete code for spam compliance. They deal with two main points. First, they state that a fax is not a commercial electronic message for the purposes of the Spam Act. Second, and more importantly for day-to-day marketing activity, they set conditions that must be met when a commercial electronic message includes an electronic address to be used for sending an unsubscribe message.
That means the regulations are especially relevant to businesses that send promotional emails, SMS campaigns or similar electronic marketing and rely on links, reply channels or web forms for opt-outs. If your unsubscribe process creates cost, friction or unnecessary data collection, these regulations are directly relevant.
