Adam Demos was born in Wollongong, a city on the coast of New South Wales, Australia. Demos grew up on a hobby farm with his family and graduated from Dapto High School in 2003, a school focused on rugby. He also attended the film and television school Screenwise.
Demos was a construction worker in his hometown. He joined his father in the demolition business in his teens and continued even after high school. Where he came from, acting wasn’t really a part of their lifestyle.
