What the Team is Known For

Mallesons fields a well-staffed, comprehensive competition/antitrust offering with global reach and a particularly impressive, fully integrated regional network, noted for its engagement with large, complex mandates. The firm's merger clearance experience extends to the representation of major multinational clients on the acquisition of Australian targets, and the litigation practice frequently acts in high-profile prosecutions, including cartel cases. The team is notably active on behalf of blue-chip clients from the financial services, pharmaceutical, resources and telecommunications sectors, and is adept at the handling of access issues and other matters in the energy and infrastructure spaces. A conspicuously loyal clientele benefits from the firm's in-depth knowledge of the Australian Competition and Consumer Commission (ACCC), state and Commonwealth regulatory bodies and industry associations.
