Stephen von Muenster


“I’m inspired by the convergence of technology and creativity – how technology is being used to create engaging commercial communications. Each day new ideas are emerging, and as a firm we are constantly evolving and updating to provide enabling capabilities for our clients. I find it exciting to be a critical part of a client’s journey, providing them with solutions so they can realise their vision. Oddly enough, outside work I’m passionate about all things vintage. So at work I’m living in the 22nd century, at home the 19th century!”

Stephen is a practicing solicitor and Partner at von Muenster Legal, a specialist technology, media and communications firm based in Surry Hills, New South Wales.

He is presently assessing the ACCC response to the Digital Platforms Inquiry and the related Ad Tech Inquiry and providing assistance and guidance to the industry and agencies.

Stephen successfully conducted the agency test case in the Supreme Court of NSW – Ikon Communications v Advangen International Pty Ltd [2018] NSWSC 1650 – in which Ikon Communications was awarded substantial damages and legal costs when its former client failed to pay professional fees and media costs.
