Prudence Smith's practice is focused on competition, consumer and regulatory law. Drawing on many years at the Australian competition and consumer law regulator, she is able to help clients achieve favorable outcomes.

She advises and represents clients in Australia, New Zealand, Singapore (with locally registered Jones Day lawyers), and throughout the Association of Southeast Asian Nations (ASEAN) on a broad range of competition law issues, including cartel and anticompetitive conduct investigations, authorizations, and notifications, as well regulatory issues including Spam Act and AML compliance.

She also regularly advises on significant and complex merger clearances and joint ventures, including many cross-border transactions. She has in-depth experience in complex competition and consumer litigation and is regularly sought out by clients that are facing significant and complex regulatory and private litigation issues involving competition law (such as private actions for anticompetitive conduct, including refusal to deal or misuse of market power) or misleading and deceptive conduct representations. Prudence is also often called on by clients who have received a statutory notices for the production of evidence or who are the subject of a search warrant.
