Dispute resolution


We have leading-edge experience in advising clients on large-scale litigation and class actions. Our litigation partners have been involved in most of the significant claims and major class actions in Australia over the last 20 years.

We are unique amongst Australian firms because we act for both plaintiffs and defendants in large-scale litigation and class actions related to antitrust/competition, corporate, financial services and tax matters. Members of our team are widely recognised litigation and class action experts.

We also have considerable expertise in acting for litigation funders who drive class action litigation in Australia. This experience provides us with invaluable insights into the judgment calls made for both plaintiffs and defendants in the conduct of complex claims. Our clients obtain commercially attractive results based on our savvy, strategic and non-process driven advice.

We provide a compelling offer of outstanding litigation services. Our independence and relative conflict-free positioning enables us to pursue plaintiff-based litigation, as well as defendant work.  Our focus on providing strategic advice to Australian funds on class actions puts us in a unique position to prosecute their claims.

We are dedicated to the causes we fight, and to achieving the best case scenario for our valued clients.
