New research puts AI usage at 77% of Australians aged 16 plus, with ChatGPT the clear leader on 13.8 million users. Roy Morgan's narrower measure shows the same pattern. AI is now mainstream consumer behaviour.
ChatGPT is now the front door to AI for most Australians. That changes where buying journeys begin.
AI has gone mainstream in Australia. New Telsyte research puts usage at 17.4 million people, or 77% of the population aged 16 and over. ChatGPT leads on 13.8 million users, ahead of Google Gemini on 9.1 million, Meta AI on 5.6 million and Microsoft Copilot on 5.4 million.
Roy Morgan's research lands on a lower headline because it measures a tighter window, tools used in an average four weeks rather than over a year. Even on that stricter measure, 13.6 million Australians use AI tools and ChatGPT still dominates with 10.5 million users, more than double its nearest rival. Two different methods, the same story. ChatGPT is the front door to AI for most Australians.
The gap between the two numbers is worth holding onto. Broad annual usage is huge. Regular monthly usage is large but smaller. That difference is the line between people who have tried AI and people who have built it into their week.
Why it matters
When most of your market is asking an AI assistant before they ask you, the assistant becomes part of the buying journey whether you planned for it or not. People are using these tools to research products, compare options and shortlist before they ever land on a website. If you are invisible to ChatGPT, you are invisible at the start of a growing share of decisions.
For Australian marketers this reframes the AI question. It is not only about using AI to make content faster. It is about understanding that your customers are already using it, and that their first impression of your category may now be formed by a model, not by your homepage.

What to do about it
Assume your customers are researching you through AI. Test it. Ask the major assistants about your category and see what they say.
Focus on ChatGPT first. It has the reach. If you are going to understand one AI surface, start with the one most of your market uses.
Make your information machine-readable. Clear, accurate, well-structured content is what these tools draw on. Vague marketing copy gives them nothing to work with.
Separate consumer use from your own use. The fact that 77% of people use AI does not mean you should pour budget into AI tools. It means you should understand the surface your customers are on.
AI is now part of how Australians find and judge businesses. Treating it as a niche is a year out of date.
