Immediation Practice Area: Mediation



I have extensive experience in all areas of intellectual property, trade practices, general commercial law and sports law. Prior to signing the Bar Roll, I was a Senior Associate at Corrs Chambers Westgarth in the Intellectual Property and Trade Practices section.

I started practicing as a Nationally Accredited mediator since 2012 during which I have written and edited problems for use at the ICC Mediation Moot Competitions held in Melbourne and Paris. 

My practice as a barrister has encompassed appeals, trials and various types of interlocutory applications for orders including injunctions, civil search and seizure orders and contempt orders. 

Some of my major clients included Rolex, Gap, Nike, Valentino, Caterpillar, Treasury Wines, Christian Dior, Louis Vuitton, Hugo Boss, Cartier, Hermes, Nokia, Rip Curl, Mambo, Australian Rugby Union, National Foods, Crazy Johns (now part of Vodafone), Hoover, Fendi, Lacoste, Vans, Viacom, Toyota, John Sands, Playgro, Rivers, Just Jeans, Adele Palmer and Bradmill.

I have also acted in mechanical and pharmaceutical patent matters for companies such as Braun, Alphapharm, Transpread International, Huhtamaki and Metallgesellschaft (now part of the GEA Group) and in allied areas such as breach of trade secrets, Crown use of IP, the IP aspects of tax appeals (R & D) and in the trade practices area she has acted in various consumer law and price fixing matters.

My sports law practice grew out of my pro-bono work for Olympic athletes which led me to my current position of  President of the Taekowondo Appeals Tribunal (recently being awarded the Ian Callinan prize at the 2019 ANZLA Annual Conference The Denis Callinan Award recognises members of the Australian New Zealand Sports Law Association (ANZSLA) who render commendable community service in the field of sports law.)
