The Designs Act 2003 (Cth) is the national law for protecting the visual appearance of products in Australia. The Act defines a design, in relation to a product, as the overall appearance of the product resulting from one or more visual features of the product. That makes the Act especially relevant for businesses selling goods where appearance is part of the commercial value, such as furniture, fashion items, packaging, homewares, tools, hardware and consumer products.
The law is not a general protection for ideas. It is tied to a product. A business cannot rely on the Act to protect a purely conceptual style, a broad product idea or a functional outcome by itself. The practical question is whether there is a product with a visual appearance that can be identified and represented in an application. If the feature you want to protect is really about how something works rather than how it looks, the Designs Act may not be the right tool on its own.
The Act operates Australia-wide. It binds the Crown and extends to each external Territory, the continental shelf, the waters above the continental shelf and the relevant airspace described in the Act. It can therefore matter to individuals, companies and other entities dealing with products in the Australian market.
