A native of Melbourne, Griffiths graduated from Victoria College with a Bachelor of Education degree in drama and dance. She worked in the theater in Melbourne with Australia's acclaimed theatre company for young people, Wooly Jumpers Inc. She continued over the next six years working with the Melbourne and Sydney Theatre Companies, starring in Sylvia, The Sisters Rosensweig, The Grapes of Wrath and The Doll House. In 2002 she starred in David Auburn's stage play Proof for the Melbourne Theatre Company and took home the Green Room Award for Best Actress in a Leading Role.

Griffiths directed her first short film, Tulip, in 1999, which went on to win Best Short Film at the Toronto and Palm Springs Film Festivals. She completed her second short, Roundabout, in 2002 to great acclaim. The film won two Best Short Film awards, one from the Australian Film Critics Circle and the other at the Melbourne Film Festival.
