Fewer filings did not mean a quieter year for class action activity in Australia. Mallesons’ The Review: Class Actions in Australia 2025/2026 examines a year of near-record settlements, renewed momentum in shareholder claims and the expanding intersection between class actions and regulatory proceedings.
Between 1 July 2025 and 30 June 2026, at least 46 new class actions were filed, the lowest number since 2016/17. Yet the stakes remained high, with more than $1.65 billion in settlements approved - the second-highest annual total recorded by Mallesons.
The year also brought significant developments in shareholder class actions and a growing intersection between class actions and regulatory action, alongside continued activity in employment claims and other emerging areas of risk.
Key highlights include:
- Filings fell, but settlements remained high: At least 46 new class actions were filed, while at least 20 settlements were approved, including five worth $100 million or more.
- Shareholder claims regained momentum: Brambles and Worley delivered the first plaintiff wins on causation and loss in Australian shareholder class action history, with the High Court’s pending judgment in Zonia set to further shape the law in this area.
- Regulatory overlap increased: Almost a third of new class actions intersected with a regulatory proceeding, investigation or inquiry.
- Employment claims remained strong: 13 new employment class actions were filed, second only to consumer claims at 16.
- New areas of risk are emerging: AI, cyber, data breaches, unfair trading and ESG-related claims are among the areas to watch.
Now in its 14th year, The Review looks beyond the headline numbers to examine how class action risk is evolving and what businesses and boards should be watching in the year ahead.
