Rob Holdsworth said she was "The most exciting voice since Sutherland"[21] and The Age wrote: The Australian-born soprano sang one of opera's most demanding roles flawlessly, from florid coloratura to (literally) high drama via ravishingly delicate pianissimos.

[22]The Arts Desk praised her performance in Das Liebesverbot: In Wagner Dix seems to me more impressive, personable and occasionally witty in this demented role which veers from Beethoven's Leonore – to bel canto heroine and even French comic minx .The gleaming if slightly metallic middle register gives great focus to intelligent recitative, and all the top notes work for her.
