Mayhem began her career in the adult entertainment industry as a dancer at the Spearmint Rhino on Tottenham Court Road.[1] In December 2000, she moved to the United States (allegedly on a dare) to begin acting in pornographic films.[citation needed] Her first scene was with Lee Stone in Real Sex Magazine 38.[4] In 2002, she won the XRCO Award for Starlet of the Year[2][5] and the FOXE Award for "Vixen of the Year".[6]
Outside pornographic films, Mayhem was a singer/guitarist in the all-girl metal band "Sweet Avenge".[2]
In 2008, she appeared in a small role in the Sex and the City film, in which she is seen through a window having sex with Samantha's neighbour Dante.
Mayhem wrote an autobiography titled Absolute Mayhem: Confessions of an Aussie Porn Star,[2][7] which was released by Random House Australia in 2009 in her native Australia and by Skyhorse Publishing in North America the following year.[8][9] A French translation was published in 2011 by Camion Noir.[citation needed]
In August 2010, she announced that she had retired from pornographic acting, after over 400 films,[10] and that she was engaged to a Sydney veterinarian.[11]
