As of December 2025, data indicates that Australians aged 25-34 represent the largest user base of ChatGPT, followed closely by the 18-24 demographic. This usage is tracked through OpenAI’s anonymised usage data, combined with independent market research conducted by firms like Roy Morgan and Statista, which now includes detailed breakdowns for Australian users.
ChatGPT’s user data collection operates via a system of telemetry. When a user interacts with the platform – generating text, refining prompts, or utilising features like custom GPTs – anonymised data points regarding session duration, feature usage, and broad demographic indicators (derived from account creation details and optional profile information) are recorded. OpenAI’s privacy policy, compliant with Australian Privacy Principles (APPs), governs this data handling. Currently, ChatGPT Plus subscriptions in Australia cost AUD$30 per month, and access is generally available nationwide. In 2026, OpenAI plans to integrate more robust age verification processes to improve demographic accuracy, responding to concerns raised by the eSafety Commissioner. The platform also now includes features like voice input and image analysis, broadening its appeal across age groups.
Essentially, ChatGPT’s usage is monitored through anonymised data collection, providing insights into user demographics and platform engagement.
