GA4 audiences allow you to group users based on shared characteristics and behaviours on your website or app, enabling highly personalised marketing campaigns and a better understanding of your customer base. As of early 2026, these audiences are crucial for effective digital advertising and optimisation, particularly with increasing privacy regulations.
- Demographic Data: Target users by age, gender, location (including postcode targeting for specific Australian regions), and interests.
- Behavioural Triggers: Create audiences based on specific events, like viewing product pages, adding items to a cart, or completing a purchase.
- Predictive Audiences: GA4 now features machine learning-driven audiences predicting churn probability or potential revenue, helping you proactively engage high-value customers.
- Custom Combinations: Combine multiple criteria using ‘AND’ and ‘OR’ logic for incredibly granular audience segments.
In 2026, Australian businesses need to be particularly mindful of data privacy when building audiences. Current systems include enhanced consent mode integration, ensuring GA4 respects user privacy choices and complies with Australian Privacy Principles (APPs). Furthermore, GA4’s modelling capabilities help fill data gaps created by cookie restrictions, providing more accurate audience insights even with increased privacy focus.
