Jacqueline Susan McKenzie (born 1967) is a classically trained Australian actress of stage and screen.
Born in Sydney, New South Wales, McKenzie attended Wenona School in North Sydney until 1983 then moved to Pymble Ladies' College, where she graduated in 1985 with her Higher School Certificate. Known at school for her fine singing voice, McKenzie was cast as Nancy in Oliver! then in Godspell (both a co-production with Shore School) and later in Brigadoon (a co-production with Knox Grammar School), sharing the stage with Hugh Jackman, who was a student at Knox at the time.
McKenzie studied for a Bachelor of Arts degree at the University of New South Wales. While at university, she began modelling. Represented by Cameron's Management, she worked in both print and television media. She also took regular singing lessons with Australian vocal coach Bob Tasman-Smith. In 1987, McKenzie was cast as the lead in the pilot of television series All The Way alongside Ben Mendelsohn, Robert Mammone, Rowena Wallace and Martin Sacks. During this time, she came to the attention of casting agent Liz Mullinar, who had cast Judy Davis in My Brilliant Career and Nicole Kidman in Dead Calm. Following advice from Mullinar, McKenzie auditioned for the National Institute of Dramatic Art (NIDA) and was accepted. Opting out of both her arts degree and All The Way, McKenzie attended NIDA in 1988. She graduated in December 1990.
