Helo,
I'm recent graduate from France and I'm looking for a LLM in Australia next year...
I'll would be grateful if someone can tell me what is the best LLM program in taxation in Australia ?

both universities of sydney and melbourne have pretty solid programs - with top australian and (occasionally) internaitonal academics, and practitioners

Both University of Melbourne and the University of Sydney offer a LLM in taxation. Both are top law schools, but I choose Uni of Sydney. They offer more subjects and more flexibility than Uni of Melbourne. I was highly satisfied with my studies and the programme is very reputable and challenging.
