If you use AI to write marketing copy, blog posts, product descriptions, or any other content for your business, you probably assume you own it. The answer under Australian law is more complicated: and the implications are worth understanding before you build workflows around AI-generated content.

The Copyright Act 1968 requires a human author

Australian copyright law protects original works created by human authors. The Copyright Act 1968 doesn’t explicitly address AI-generated content, but the courts and the Australian Copyright Office have been clear on the underlying principle: copyright requires human authorship. A work created entirely by an AI system: without meaningful human creative input: is unlikely to attract copyright protection in Australia.

This matters because it means AI-generated content may be in the public domain from the moment it’s created. Anyone could legally copy and republish it. Your competitor could take your AI-written product descriptions and use them on their own site without infringing your copyright: because you may not have any copyright to infringe.

What counts as human creative input?

The law isn’t settled on exactly where the line falls. But the general principle is that the more creative judgment a human exercises in producing the final work, the stronger the case for copyright protection. Writing a detailed, specific prompt that shapes the output significantly is more likely to support a copyright claim than typing “write me a product description for a coffee machine.”

Editing, curating, arranging, and meaningfully revising AI output also strengthens the case. If you take AI-generated text and rewrite significant portions of it, the final work: to the extent it reflects your creative choices: may attract copyright. The AI output is more like raw material than a finished work in this scenario.

Who owns the AI’s training data?

There’s a separate issue that affects businesses using AI tools: the content those tools were trained on may itself be subject to copyright owned by third parties. Several major lawsuits in the US are currently testing whether AI companies infringed copyright by training on scraped web content without permission. The outcomes will affect Australian businesses too, though Australian law may handle the question differently.

The practical implication: AI-generated content that closely resembles existing copyrighted work: because the model was trained on it: could expose you to infringement claims, even if you didn’t intend to copy anything. This risk is highest for content in specific styles or formats closely associated with identifiable creators.

What this means for your business

Three practical steps:

Edit AI output meaningfully: don’t publish raw AI text unchanged. Revise it, add your own knowledge and perspective, and make creative decisions that are demonstrably yours.
Keep records of your prompts and process: if you ever need to demonstrate human creative input, documentation of how you worked with the AI will help.
Don’t rely on AI-generated content for trade mark or IP-sensitive applications: logos, taglines, and brand elements should have clear human authorship. Get legal advice if the stakes are high.

The law will catch up to AI eventually. For now, the safest position is to treat AI as a drafting tool, not a content creator: and to make sure your own creative contribution to the final work is real and documented.
