Monica Mayhem was born and raised in Brisbane, Queensland, Australia. She moved to Sydney alone when she was 16 to pursue a career in modeling and acting but ended up in the financial world, and before long she was involved in the foreign exchange and futures trading markets. She left Australia to travel around Europe, then moved to London, where she worked in the IPE brokerage division of the renowned firm of Salomon-Smith-Barney. Tired of the dry and boring financial world, she was looking for a little excitement when she ran across an ad for "glamor" models. She found out that it involved nudity but decided to give it a shot anyway. She wound up doing some softcore photo shoots in London. She then decided to try exotic dancing and managed to land a gig at the world-famous Spearmint Rhino club. One night she spontaneously decided to leave London and jumped on a plane to the US. She eventually made her way to Los Angeles, where she broke into the porn industry, and the rest, as they say, is history.
