Her acting credits haven't gone without notice, however.

On the back of her success in Australia, McKenzie ventured to the United States. There, she starred in films such as "Preservation and Human Touch", "The Divine Secrets of the Ya-Ya Sisterhood" and "Deep Blue Sea". Jacqueline also took on numerous television roles, making appearances in Nightmares and Dreamscapes and Without a Trace. In 2004, she joined the cast of the successful science fiction series The 4400, where she played one of the lead roles. As cold NTAC agent Diana Skouris, she later warms to the people around her as she grows slowly disenchanted with her role within the organization. McKenzie also returned shortly to Australia, playing a guest role on the television series "Two Twisted".

Jacqueline is also an accomplished singer and painter, with one of her songs being used on the second season finale of "The 4400". In 2009, she was cast in the Fox series Mental, where she plays Dr. Veronica Hayden-Jones, the rival of the lead in the hospital.
