Johnson Winter & Slattery has one of the pre-eminent antitrust/
competition teams in Australia. We are known for our ability to:

  • Provide strategic and creative solutions on significant “bet the ​firm” matters.
  • Obtain antitrust clearance for complex, multi-jurisdictional mergers and acquisitions.
  • Act for immunity applicants or defendants in global cartel investigations and prosecutions including in relation to follow on class actions.
  • Advise on ACCC investigations into exclusive arrangements, joint ventures, and other alleged anti-competitive conduct.
  • Defend proceedings alleging abuse of market power.
  • Advise on highly complex access to infrastructure and access pricing issues.

We have also acted for the ACCC which provides our team with unparalleled insights when it comes to getting a deal through or defending regulatory investigations or prosecution.

We continue to be involved in landmark work across the full range of competition work in Australia , including being involved in almost all the major cartel cases including current criminal investigations and major roles in some of Australia's largest transactions.
